pcv valve for an evo iii engine

[timm98gst]

i checked autozone and advance auto parts for a pcv valve for my evo iii engine and they don't carry anything specific for it. i tried using one from a 95 eclipse gst and it doesn't want to screw in. it is a purolator pv1021. seems like the threads are different or something. anyone have a suggestion on what pcv valve to use?

I think the evo 1-3 motors are the same as usdm 6 bolt's, so you could try one from a 1st gen.

If it's just slightly different thread pitch, run a correct size tap for the 95 pcv through it and you should be fine. I had to do the same when I replaced the pcv with a 1/8 npt straight fitting.
