I have replaced timing belt water pump all tentioners new serpentine belt pcv valve and still there but when I take the pcv valve out the noise goes away any suggestions ? I think something to do with intake manifold very small leak of some kind?

 

Dude I have this exact problem. I am thinking it is some type of vacuum leak. Not exactly sure but it appears to be near the manifold.

These are the two videos I posted to youtube. I have done exactly what you have done so far. As far as the timing belt and tensioners and new serpentine belt, o rings for power steering all of that.

My thinking is that its the EGR gastet or manifold gasket not sure though. Let me know when you find something out!

Also, I really though it had something to do with the power steering but its not. It is coming more from the manifold side so its something around there.

 

Yeah that is definitely the same noise and have pretty much came to the same conclusion I think I am going to do a valve lash adjustment soon and replace the intake manifold gaskets and the plenum egr gasket. Hopefully that will do the trick. Let me know if you find it before I do because it is extremely annoying

 

Hey I was just doing some pondering,

Since its not the PCV valve we both know because we replaced it. It has to something with pressure in the system. Like, we depressureize the system by removing the dip stick. Then the pressure builds back up and hence the noise. This vac leak has to be so small its not even funny. I am with you on its either the EGR gasket or the manifold gasket.

I am thinking about removing the hole manifold to clean it out and what not so we will see.

 

Are you guys using oe pcv valves? I've chased down so many weird problems that ended up being pcv valves, that I won't use aftermarket anymore. And not just acura either. I've run into aftermarket applications where an acura tl pcv valve was also listed as an f-150 application. Calibration and flow can be critical, and I don't think anybody does it better than the original mfgr. Just my 2 cents, but I hope it helps.

 

I know what you mean and I have heard that it can be a problem but I have only really heard that being a problem with after market EGR valves and IACV. But my issue is not the PCV value for sure. The sound can be heard coming from around the manifold area. Espcially when the car is shut off it sounds like the car takes one loud gasp of air. Like a sucking sound.

 

Hey just to give you an update I replaced the EGR valve gasket. When I took is off it was definitely gunked up . So far I have not heard any chirping noise. We will see how it goes. It literately took about 10 mins. I had to scrape the old gasket of the EGR valve because it was baked on there pretty good. I bought one from Advance for about $3.00.

 

And it was good for like the first half of the day then after that it started to make the same noise haha. Oh well, it was worth a try .
