Hey Robert, my original issue was rough idling and the car ran like crap. The way I troubleshot it was to clean MAF sensor, then replace the pcv valve. I then moved to replacing the VCG which helped a bit but the issue remained. The last thing that fixed the issue was the precat sensor. If you have the squealing noise you might want to start with the PCV if your VCG is still good and not leaking (mine was done for). It's important to remember that the entire VCG is part of the PCV system and sometimes might get clogged. You would know if you replace just the PCV valve. I have videos for all 3 projects posted on my channel. Hope this helps. The squealing noise I wasn't sure if it was pronounced like others I've seen on yourtube.
@@nyst8fmind Thank you for that info. I replaced the entire valve cover (URO brand) and I'm still getting a squealing noise when the car comes up to operating temperature. Not sure what else to tackle if I'm being honest to get rid of the dreaded noise. I did a PCV test with the flame and it wasn't sucking in air through the little hole, so I'm assuming my VC/PCV isn't the issue.
@FailofWar127 this reminds me of a squealing noise I was getting when my car was around 60k miles, can you tell me if the noise is coming from the exhaust turbo side? Pass side to be precise. If so I suspect your issue is the turbo boost solenoid.

@@nyst8fmind I think I might have a few noises going on. I get some chirping from the pulleys, but really the most pronounced one is whenever the squeal from the pcv/valve cover or main seals which is driving me crazy. An interesting observation, when the car is cold the negative vacuum is not as strong, however, after the car is fully warmed up the vacuum seems a bit stronger and the squealing noise starts, especially when you rev the engine
Great video. I'm doing this job very soon and the info on here was very helpful. Good choice with Elring!
Good to hear that the video was helpful, much appreciated. I'd love if you can help me support the channel by subscribing. Thank you!!!
Did this fix your squeal noise related to the PCV?
