I am having trouble trying to locate where the PCV valve is on my 1990 GXE. I have put 234,000 miles on my car over 10 years and I don't ever remember anyone change the PCV valve. I bought one several years ago and planned on changing it myself. I could not locate where the original one was mounted. My book says it is located toward the back of the engine close to the fire wall. I still have never been able to find it. Can anyone please help this shade tree mechanic by giving a simple explanation that maybe a 3rd grader could understand?

Thanks very much,

David

 

Don't feel bad, I haven't found mine either. I have 199,040 miles on Maxine, and I have yet to find it. Let me read through my chilton's manual and I'll repost where it actually is

 

i think this might help. it should be located between this junction.

 

I also copied a diagram from my chilton's manual, this may be a better picture

 

its a side view of what i circled. just unscrew this black piece and replace it. i recommmend fuel filter change also and possible some fuel system cleaner and oil change. use chevron with techron, great stuff

 

on my website, I have pics of where all the ECCS components (PCV and lots of other stuff) is for both VE and VG engines

click on link in my sig and it's in the how-to

enjoy

 

how often should these parts be changed? i have 88k on mine and havent changed it yet. is it due? thanks

 

Thank you very much for your help. I will try to locate it tonight. I have been running Mobile 1 synthetic for about 180,000 and changing oil every 6-7 thousand. My max does not use or leak any oil with over 234,000 and still going strong. I highly recommend Mobile 1 even though it is more expensive.

Sincerely,

David Moore

 

SO NONE KNOWS HOW OFTEN THIS SHOULD BE DONE??????
