I've been thinking about how im going to do my catch can setup. I plan on using -10 hose and fittings being that I already have a bunch from a previous build. I was thinking of how to get the -10 fittings into the valve cover and what type of ffittings to use. Someone said just to tap the valve cover but I need some more info. Has anyone done something like this?

 

Quite a few people have done it.

Drill & tap holes, remove baffle to clean out all the excess shavings, reinstall baffle and you're good to go. The cover being magnesium makes it a bit tricky but its a fairly straight forward process.

 

You say drill and tap.. what about the holes that are already in it?

 

Will a 1/2" fitting fit in a 3/8" hole that isn't threaded?

 

how are people reinstalling the baffles? or are they just not running one?

 

Rivits or you can tap the mounting bosses to accept small machine screws.

Check out R/TErnie's first post in his build thread, good details on it there: https://www.evolutionm.net/forums/al...4-efr7670.html

 

maybe it helps you how reinstall baffles

 

and I have done this setup with -10AN fittings few months ago and used custom catch can with two breather filters
