FinanceWiz Posted April 9 Share Posted April 9 Greetings, I just bought a 2013 Range Rover Sport HSE 5.0 naturally aspirated petrol variant made for the United States market. The previous owner drove the vehicle for a total of 175,000 miles before experiencing issues such as limited performance misfire on all cylinders, random misfire, and misfire within the first 1000 revolutions after starting. Subsequently, he left it parked with a depleted fuel tank for about one year. I visited their residence, replaced the battery, and successfully started its operation. I transported it home using a caravan and started the process of diagnosing the issue. I refuelled the vehicle with 93 octane petrol and added one bottle of injector cleaning. The vehicle operated well for 5 minutes till reaching the petrol station, but while returning, I had limited performance and a blinking check engine light. The current code indicates a misfire in cylinder 6. All of the misfire codes described above are considered permanent codes. My current progress includes removing the 02 sensors, which seem to be functioning well in terms of cycling. The fuel pressure seems to be in good condition. The rail pressure is 3000 kPa while the engine is at idle. I emptied the oil to inspect for any signs of contamination from coolant or fuel, but it does not seem to be polluted. The user disconnected the spark plugs on the driver bank (left side in the USA) cylinders 2, 4, and 6, and saw the accumulation of gasoline in cylinders 4 and 6. Can we conclude that these are faulty injectors? I am certain that they are authentic. Will the gasoline leak if the coil is faulty? I am willing to do any suggested testing, however, I would appreciate input from anyone that has knowledge and experience with these engines. Thank you.

misstki Posted April 9 Share Posted April 9 I am unsure whether your endoscope has a 'side view' feature as my Teslong device does. However, it is crucial that you refrain from using the motor any more until you have determined if there is a stuck valve, which may now be damaged, or if it is just a case of misfiring. The term "hydro" in the context of 'hydrostatic lock damage' might result from the presence of any non-compressible fluid, not only water. Petrol, petroleum and cleaning chemicals.... I anticipate that you will allocate funds for the replacement of the chain and sprocket, most likely the replacement of head gaskets, and maybe the restoration of the valvetrain. Is there a possibility for further things? "Habit and laziness?" ... After reaching that point, it would be prudent to also replace the pistons, rings, rod, and main bearings.

FinanceWiz Posted April 9 Author Share Posted April 9 Thank you for responding. The timing was adjusted 30,000 miles ago and the engine remains quiet at warm idle. Currently, I lack a camera with the capability to capture images from an upward perspective. However, I want to promptly get such a camera today. It would be advantageous to have this here. I want to ensure that the vehicle is really worth renovating before investing too much effort into it. My strategy involves removing all 8 plugs and visually inspecting each cylinder for the presence of gasoline. Additionally, I will examine the valves using the newly acquired camera. If all components seem to be in satisfactory condition, I will replace the current injectors and coils with the new ones. I purchased the vehicle for a sum of $3700. Currently, after accounting for the cost of the replacement components and title work, my total expenditure amounts to $5400. Not bad. If I am able to get optimal performance by installing the new injectors and coils, I will continue with the current course of action. Does the pooling of gasoline serve as a definitive indication of faulty injectors? I am optimistic about this since it seems that several individuals have had a malfunctioning problem due to faulty injectors. Link to comment Share on other sites More sharing options...
misstki Posted April 9 Share Posted April 9 That is a nice outcome, but if no further actions were taken, it is likely that the issue is in the rings and bearings, rather than simply the injectors. The outcome is contingent upon the quantity and severity of heat stress resulting from faults in the cooling system. Link to comment Share on other sites More sharing options...

misstki Posted April 9 Share Posted April 9 Excellent beginning. The starting price for the vehicle was over $14,000, considering its excellent condition in terms of body, glass, paint, interior, electricals, and suspension. I anticipate investing a another $15,000 before relinquishing ownership of it. It is advisable to use injectors of the same brand for all 8, even if they are not of the same age. They should improve their calibration and cooperation. I installed 4 out of a total of 8 new products made by a third-party manufacturer, namely from the 1357 bank. Did not find it entertaining. I purchased a set of 8 original equipment manufacturer (OEM) Bosch parts and replaced the 1357 set with the 2468 set that was still on the original 112,000-mile veteran Bosch parts. The issue has been successfully resolved. Link to comment Share on other sites More sharing options...
misstki Posted April 9 Share Posted April 9 As long as the substance is gasoline and not glycol, then sure. 'Hung' in the open position, else there will be a gradual return to the closed position. Prioritise doing an endoscopic examination before performing either a compression test or a leakdown test, since both tests may obscure signs of a malfunctioning injector. Next, do a compression test and a leak-down test. You are "due", if not significantly overdue, for head gasket failure and leaking. An AJ Vee motor does not have a lengthy lifespan. The design is influenced by cost-conscious individuals with inadequate discernment. It is advisable to invest in a complete overhaul of the engine every 100,000 miles rather than waiting until it reaches 200,000 or 300,000 miles. This is particularly true for high-quality engines made by reputable manufacturers such as MOPAR, GMC, or the most reliable Asian engines created by skilled engineers and backed by knowledgeable financial analysts. Note: Knowledgeable financial analysts advise Engineers to strive for engine and powertrain reputations that are impervious to failure. Observe the Dodge-Cummins and the Toyota Land Crusher.

FinanceWiz Posted April 9 Author Share Posted April 9 I have also purchased the Teslong camera from Amazon. That is currently under progress. I am uncertain whether investing in a complete reconstruction is financially justifiable. Regardless of the repairs, the truck may not retain its worth. I shall proceed incrementally. I need this automobile to be functional for local travels and other purposes, since it will be the third car for my household. It will not exceed an annual mileage of 4000 miles anymore. I really oppose the idea of doing a rebuild. If it becomes necessary, I would likely choose to sell the item instead. Indeed, the vehicle with a price tag of 3700 dollars had just one previous owner and was in great condition. I have included an image. It is commendable that you brought up Chevrolet, GMC, and other similar brands. Although I have a preference for GMC, I have always been fond of the aesthetic appeal of the RR Sport HSE. Currently, I am in the process of doing an LS1 engine swap on my 1969 Camaro. Therefore, I would want to focus most of my time and financial resources on this project. This vehicle was a risky proposition with an equal chance of success or failure. The vehicle stayed stationary for a duration of 1 year, during which it was said to have been operational but had limited performance and misfires. While searching, one tends to anticipate negative outcomes. However, I have come across several blogs where individuals have replaced faulty injectors and coils, resulting in significant improvements. I am optimistic that this is the situation in this particular instance. I will ensure that this remains up to date. Dislike coming over unresolved old threads.

misstki Posted April 10 Share Posted April 10 Equivalent to dwellings. Not a single one of them does. JLR vehicles are inferior to many others. Indeed, that is precisely what made it really affordable for YOU to have! The user's text consists of a single emoticon, specifically a smiling face. In my particular situation, I chose to acquire the 2005 XJ8-L after a period of almost 20 years of retirement and just before reaching the age of 70. In my late 70s, I undertook the task of tackling the L320, which I found to be not very burdensome. Significant renovations were part of the proposal. However, I do not have a strong desire for a single 'daily driver'. I have never been interested in television or seeing others engage in sports or sexual activities. Therefore, tinkering with vintage motorcars serves as a diversion, preventing me from frequenting bars and brothels. With the inclusion of current features such as ABS, airbags, and others, vehicles have become safer and more practical, which is contrary to my original desires. Create an exact duplicate of a late 1930's Alvis "Speed 20" by using detailed technical drawings and starting with the raw metal materials. The automobile is an improvement over my 1959 TR3, but it does not provide much more comfort while driving in rainy conditions. Additionally, one may encounter a hazardous situation if a distracted driver under the influence of THC gummies collides with them while texting. The XJ8-L and RRS-HSE-Luxury models provide more comfort, safety, and practicality. However, some individuals argue that opting for pubs and brothels would have been a more cost-effective choice. Particularly suitable for a classic 1945 frame! Belongs to me. Exclude the motor vehicles. Link to comment Share on other sites More sharing options...
misstki Posted April 11 Share Posted April 11 At little more than one-third of the price I spent for mine (nearly $14,000)? I would have purchased it immediately, without hesitation, as quickly as possible, in the span of a minute in New York! Due to my proficiency in using a computer, I am now able to efficiently search for inexpensive components, whereas my limited physical abilities prevent me from effectively using a wrench. I estimate that I can successfully carry out a comprehensive reconstruction of an AJ V8 engine for around $4,000 worth of components. Considering that I want to retire at the age of 90, I only need a car for a maximum of 10 years and a mileage of 30,000 miles or less. I am particularly interested in a Jaguar that has double the fuel efficiency on the highway, specifically achieving 34 miles per gallon at speeds of 65-70 miles per hour. Reconstruct? Given my age, it is more convenient to remove the engine from the vehicle and work on it while it is placed on an engine stand or bench, rather than contorting myself around the body of the vehicle or straining my back below the frame.

FinanceWiz Posted April 11 Author Share Posted April 11 The substance contained in the cylinder is a vibrant orange coolant. Can coolant enter the cylinder via the intake system? The vehicle exhibits no signs of smoke during operation. I successfully drove a distance of 3 miles to the petrol station, but encountered a problem on my way back. The oil is devoid of impurities and free from any coolant contamination, while the coolant seems to be a vibrant orange colour and is also free from any impurities.

misstki Posted April 11 Share Posted April 11 I agree. The AJ Vee engines has a remarkable capacity. They may repurpose their malfunctioning head gaskets into reed valves. The process involves drawing coolant into the cylinders, where it is heated and then expelled out the exhaust with a little smell. Importantly, this process ensures that no combustion gases enter either the crankcase or the cooling system. Although the endoscope can clearly identify it, a typical color-change test-liquid exhaust-gas detector will indicate the absence of gas entering the cooling system. The vehicle may remain stationary for more than an hour, continuously emitting false information. Accelerate the engine, causing a substantial increase in temperature. This causes the coolant system to release pressure, resulting in coolant being forcefully expelled, as if attempting to fill containers for sale. I have been there, done that, got the t-shirt. Head gasket repair may be performed in situ. Many individuals on this site have accomplished the task. If the block has to be decked, new rods, pistons, and rings are required, along with potential replacement of rod and/or main bearings. Additionally, the crank should be polished and an improved oil pump is highly suggested due to the failure mode of the original pump. Detaching the sump/pan from the block while it is in its original position will not suffice. Mill must be removed. And it is necessary to do so. Once outside, it is not unpleasant to work on. There are films showcasing complete restoration projects. Link to comment Share on other sites More sharing options...
FinanceWiz Posted April 11 Author Share Posted April 11 This information is excellent. Your observation is accurate. The vehicle operates well without any issues. The coolant is replenished once the engine is undergoing the cooling process. As I am already 4400 units deep into it, I would consider listing it for sale, informing potential buyers of the existing high-grade (HG) concerns, and assessing the offers I get. I believe that the investment of time and money will not provide a worthwhile consequence. I am little angry, but that is the nature of things. Thank you once again for the information. The automobile was experiencing a cyl6 misfire current, with the check engine light blinking while attempting to drive, and the limited performance indicator also flashing. When the vehicle was not in motion, the limited performance issue resolved itself and the engine light remained on without flashing. Link to comment Share on other sites More sharing options...
misstki Posted April 11 Share Posted April 11 One of these may temporarily seal it: The efficacy of "Snake Oil" may be temporarily effective. A) The procedure involves removing the t-stat, flushing the system, purging it, and then refilling it with water alone. No glycol should be used in the system. Glycol becomes compatible only when it has solidified. https://thermalweld.com/ Link to comment Share on other sites More sharing options...

misstki Posted April 11 Share Posted April 11 I have not personally tried the only one. It is possible to apply Kseal 'ultimate' even while there is still Glycol present in the system. It seems that the system functions more effectively when it is first flushed with a 'de-greaser' solution, rather than a strong alkali. Subsequently, it should be flushed with plain water, and this process should be repeated several times. The website link provided is for the product "K-Seal Ultimate" on the official K-Seal website. I used a pair of bottles on each occasion. Semiannually. The majority of other products, such as Barr's Leaks, that were formerly considered very beneficial for repairing leaky brass radiators, have little or no effect on aluminium heads and blocks. None of these solutions provide a permanent solution for the AJ 5.0l V8 engine. One of the main reasons for its limited lifespan is the poor design of its cooling system, which leads to repeated thermal failures similar to the first catastrophe that caused the head gasket to fail initially. If you attempt to use the sealant just for a brief period: - Initially, it is important to adhere to the directions provided by the manufacturers. Indeed. Subsequently: Run the engine with a header tank cap that is not pressurised, loosened, or drilled. Ensure that you have a minimum of 2 US gallons of water with a 30% glycol mixture for the summer, and for the winter season. Inspect the level and replenish as necessary each time you start the engine. Limit the maximum revolutions per minute (RPM) to prevent the water pump from malfunctioning at high RPM. Avoid using excessive force to achieve rapid acceleration or towing a trailer. Establish a Senior discount account with a reliable flat-bed recovery transporter. You may expect to use it for local errands for many years, and you will only need to flatbed it around once every eighteen months. We accomplished.... 🙂 If you have a sufficient level of like for it? Subsequently, you may allocate funds and arrange the motor for an extended duration. The Maserati brand is using a Ferrari V8 engine.

FinanceWiz Posted April 11 Author Share Posted April 11 By chance, I began looking about resolutions and stumbled into the blue devil HG sealer. Intrigued, I started perusing the testimonies. They have made significant progress from their early days of using sawdust. They are likely silicates that undergo combustion when exposed to the combustion gases, resulting in the formation of a glass barrier at the leak. Given its few side effects, this seems to be the first course of action to be pursued. Now I only need to choose which one. I do not have any plans to tow or go on extended journeys with this vehicle, since it was never my aim. Merely confined to a certain area and providing a sense of ease and convenience. Are you familiar with the blue devil brand? Link to comment Share on other sites More sharing options...
FinanceWiz Posted April 11 Author Share Posted April 11 The truck operated well, but after stopping for petrol and returning to the vehicle, I had misfires, poor running, and limited performance. After doing extensive diagnostics, I discovered the presence of coolant in cylinder 6 and a smaller amount in cylinder 4. After thoroughly removing all the dirt and debris, I started the vehicle and it operated smoothly and without any issues for a duration of 40 minutes. There were no warning signs or check engine lights, and no signs of smoke. The only indications observed were a rough idle and the emission of coolant vapour or a noticeable coolant odour upon first startup. After operating the vehicle for 40 minutes, I released the pressure in the cooling system by removing the reservoir lid and let the car to cool overnight. Today, I examined cylinders 4 and 6 and found that they lack moisture. It has been verified that there is a leaking head gasket that allows coolant to enter the cylinder while the engine is turned off. When the engine is heated and not operating, the cooling system pressure propels the coolant into the cylinder. The absence of combustion bubbles in the coolant and the lack of oil or coolant mixing in any system indicate that the leak is likely to be minor in size. I believe I am a suitable candidate for the head gasket sealer endeavour. Theoretically, it should infiltrate the gap between the water jacket and the cylinder, where the breach is located, and undergo solidification over a few drive cycles when it comes into contact with the exhaust gases, and so on. If I choose to do this task, I will thoroughly record my progress and provide a detailed report afterwards. Link to comment Share on other sites More sharing options...
misstki Posted April 11 Share Posted April 11 Similarities to what I encountered. The sealant will only be effective for a limited duration. Based on my observation, it seems that the head/block is not particularly rigid compared to well-designed light-alloy Vee motors. That is the reason why the head gaskets fail readily when the defective cooling system design causes excessive stress initially. Link to comment Share on other sites More sharing options...
