Re: catch cans-LS

Are you at least running the stock PCV? I am going to run a mighty mouse system but there are plenty of good ones out there (mishimoto, elite engineer)

I run dual MMS cans now,great craftsmanship and does a fine job of catching vapors etc.I drain them once a month basically as the vapors turn into a nasty sludge on the bottom. A proper single can should be all you need with decent size lines.

Re: catch cans-LS

i run a universal moroso oil/air seperator from the driver valve cover PCV valve, out of the seperator is a McCaster Carr check valve that goes to the top of the intake. The pass side valve cover goes to a JAZ tiny oil catch can with filter.

It operates like a stock PCV, but it seperates the oil from the vapor before going to the intake. WHen in BOOST the check valve closes before the oil/air seperator and any pressurized crankcase gases will push out of the pass valve cover into the vented catch can. when its working normally, the engine consumes vapor via the driver valve cover and the pass side sucks in fresh filtered air. Couple of years like this, but limited miles (prob 2k) and I empty whatever collects in the oil/air seperator when i feel like it.
