okay. someone who knows, fill me in if you don't mind. what is the size and thread pattern of the PCV valve on the intake manifold? i'm trying to find a plug for the old hole since i'm relocating it. please??? Me love you long time.

its wierd. when i size it at the bolt-gettin place, it reads m-14 x 1.5 thread pattern, but when i try to put the plug in the hole, too damn big. and m12x1.5 seems to be too small. not to mention the thread pattern is wierd too. it doesn't exactly match up to anything. makes me wanna pull my hair out if i had any.

 

Probably a pipe thread. Wish I could tell you. You can get a thread pitch gauge for pretty cheap.

 

the one in the bottom of the manifold? idk i used to have a plug that matched the threads. just go to napa they will help you out bring out a few different types and just try it out. or if you got a spare manifold that would help. i just imagine everyone has a spare manifold since i got like 3 haha.

 

x2....

Housekeeping... me fluff yo pillow?

 

i got 2 extras as well

 

I believe its 1/4 NPT

 

Something told me that would be pipe thread. haha

 

yup. it was 1/4 NPT. looks like all the threaded fittings on the intake manifold are NPT of one size or another.
