2013 S60 engine produces a whistling noise and has a PCV diaphragm issue.

Greetings, My 2013 S60 emitted a sound like to that of a spacecraft when idling. I searched YouTube and saw many videos addressing the replacement of the PCV diaphragm. Consistent with the content of these videos, the noise ceased upon slightly withdrawing the oil dipstick to alleviate vacuum pressure. Procured the component and had it installed yesterday. The technician reported that the automobile no longer produces the whistling noise; nonetheless, a significant vacuum persists, indicating a potential problem may remain. He is not retaining the automobile for further diagnosis since I must transport it to the airport today.

Is it typical for a vacuum to persist? I do not remember a vacuum being included over the years I have owned the vehicle.
Is it OK to operate the vehicle for around 100 miles each way if I partially remove the dipstick? His stance is, "No, as it may ingest dirt."
What other factors could be at play?

Am I posting in the incorrect section of the forum?

Thank you.

Reassessing the PCV. What happens if you remove the dipstick or open the fill cap to ventilate the crankcase? Does the whistle cease to exist?

Indeed, the component has been substituted. My issue was if it is typical for it to still maintain a vacuum. Nonetheless, I operated it, and it seemed to function adequately for me. I will post again if the situation continues. Thank you!

Has the suction at the oil filler cap dissipated? Did you connect an OBDII device and get any codes? I am experiencing the same issue and have seen a P1071 error, indicating a gasoline combination that is too lean. Intending to remove or replace the diaphragm.

The OBDII was not connected, hence we did not get a code. Apologies. I suspect the vacuum has been removed, but I will verify this and respond promptly.

Thank you for your response. Could you please inform me of the mileage on the automobile when the noise first occurred? Thank you.

I got the vehicle inspected yesterday. A powerful vacuum is no longer present, although a minor vacuum remains. The technician states that this is typical. I neglected to verify the distance. I will attempt to verify, but it was likely about 155,000 at the time of occurrence.

Thank you for your response. 155,000 seems to be accurate. My occurrence occurred at 57,000. YouTube has shown to be a far superior resource compared to this forum. Although the repair was challenging to execute, it has proven very successful, and the vehicle is operating well.

Verify your oil level, as I have lost 0.5 quarts owing to this incident. The deficiency of integrity, honesty, and skill among the local Volvo dealership and independent mechanics licensed to service Volvos is astonishing.

I would not be astonished if I resided in Bum****, Iowa; nevertheless, I now inhabit the San Francisco Bay Area next to Silicon Valley. My Certified Pre-Owned 2013 S60 had 27,000 miles when I purchased it and required four new tires and a new battery. What on earth?

Best of luck.

Thank you for the information of checking the oil. I will monitor it attentively. Best of luck in locating a seasoned and trustworthy technician. The individual who purchased my S70 a few years before recently had a similar challenge in locating a Volvo technician. My mechanic was too far for him, and his resolution was to dispose of the vehicle. I am aware of some technicians who originated from the now-defunct Volvo dealership and have since established their own enterprises, but they seem to be increasingly uncommon.
