Using exhaust to vent crankcase?

Post by SPoole »

Has anyone ever heard of or tried using a small Y in your exhaust to scavenge crankcase pressure from your valve cover breathers?
Pros/Cons?

I have read about it, and it seems to be a good idea because the flow of exhaust will create a vacuum. I have never personally tried it, or seen anyone do it.

Also it could eliminate the need for a catch can.

you dont HAVE to have a catch can either way if you dont want. you can just run the hoses to the ground. but will get oily lol

i know what the slashcut tube in the exhaust does, but really there is no need for it and its just wasted time. everyone i know just runs catch cans/tanks. look at all the 7,8,9 second hondas....same way.

Found what I needed. It looks like wastegate dump is a good location.
