I have seen posts on here about the pcv but no good write ups on replacing it, or even pics of where its at. Its a relatively simple procedure, but maybe not for some noobies. Mine recently went bad so when replacing it I decided to take some pics to help someone out in the future. I replaced mine and now car is running great again.



this is the part number and what it looks like.



this is where its located. on the back of the valve cover. To remove the hose, use some pliers to pull the two ends of the hose clamp together to slide it back. carefully pull the hose off and use a 15mm wrench or thinwall deep socket to carefully unscrew the pcv valve. You may need to hold the other end,with some pliers, where the pcv screws on the valve cover, to keep it from moving.

 

How did you determine that it went bad? Symptoms?

 

found it during a boost leak test. During the test air was leaking through. I removed it and found the check ball inside not moving around like the new one did. I installed the new one and much better.

 

oil catch can installed early will prevent pcv's from going bad prematurely.

 

How many miles is this after?

 

my car has 51k.

 

Something to check if your dipstick is popping out.

 

Thanks, I was looking for the PCV part #. Anyone found another source/brand. These list around $24 from Mitsubishi?

 

Autozone, Checker and Pep Boys all stock the pcv (all under $5) for the Evo.

 

I'll checkout out Autozone or Pep Boys. Advanced Auto didn't have it. Maybe O'Reily or Napa too. Thanks for reply.
