Chirp sound from engine bay

RoWoX3M · 12-23-2018, 05:03 PM

Had an oil leak on my charge pipe and belt so dealer replaced my oil housing gasket. A squeal started so dealer then replaced belt and pully tensioner. Now there is a chirping sound. Quick search says maybe valve gasket is the culprit. Made yet another dealer appointment. Luckily all under warranty. Thoughts?

Sounds like a problem I've had. PCV failure. Replaced valve cover.

I sprayed some water on the belt and the sounds stops for a few seconds and then resumes. I was thinking valve cover too based on research but the sound changes when I put water on the belt so maybe it is still related to the belt/tensioner. Both were just replaced so I'm at a loss. The sound is awful. Feels like I'm in an old beater at a stop light.

What about a dry lubricant such as this:
