PCV adaptor - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

1stGenBRZ86 · 06-30-2014, 01:07 AM

Does anyone know the thread pitch for the pcv valve? I want to convert it to a -10 an fitting for a catchcan. I've read that the older EJ motors use 1/4" BSPT, which I bought, but was too small.

*EDIT*
seems like people here don't like to share knowledge, so I'll post my findings for future searches.

As per this thread (credit goes to Dan@AWD):

Should be 5/8th inch npt but I cant remember. @FullBlown includes one in their kit so he might know. If not ill pull mine out tomorrow night.

Nobody knows this? if you have a kit, just read the size on the package.

From work I can't see pictures in the tread but I guess it's about 9=>15 mm conversion for catch can install. Cusco produces a special adapter which fits and works very well (I have one):

Thats what I used to connect my AVO catch can since their adapter is wrong. Its a 3/8" standard thread I then went to 3/4 to get the right hose size. I got the fitting at an Ace hardware Nuts and Bolts store. I used high temp thread sealant.
