Oil catch can.... Good idea for a turbo setup? Looks like my engine drank a quart of oil through the throttle body over it's life . I'm thinking of running a catch can. Don't know if I can do it with turbos... Should I even use the PCV system or just install filters on the valve covers??
Thanks
Thanks
What kind of PCV system do you have now. A catch can is a great idea to keep oil out of the intercooler, piping and intake. I'd go with a catch can of venting to the atmosphere.
I prefer a catch can that maintains a vacuum source. Its better for the engine to help seal the rings if you pull vacuum from the crankcase. Mightymouse makes a really nice can which I use on my car.
Do you install a check valve similar to one installed in-line of a brake booster to keep from pressurizing the catch can?
I think if you want to maintain pcv valve system you are looking to install a air/oil separator inline with the hose from valve cover to intake. Most catch can systems are open filter vented to atmosphere from valve covers straight to can.

Sealed catch cans with vacuum are technically healthier for the engine, but a vented one is going to be better than a stock pcv system since it'll catch all of the blow by. Most race cars use a vented catch can.

I'm just using stock Pcv system but once I add boost I'll have to do something else. Found a $20 catch on eBay with site gauge that looks like it will work. Doesn't seem to vent to atmosphere.
What do you guys think about the oil cap mod. Putting a small filter through the top of the cap
