Positive Crankcase Vents
Posted: July 22nd, 2006, 8:42 am
This is something that I have always been unsure of,and that is which is the best way to have a Crankcase Vent set up.
The standard PCV set up on my car (Toyota MR2 Turbo) is to have the it feeding back into the intake pipe just before the turbo. A common assumption on the MR2 scene is that this is due to emmissions etc.
Now, most people complain of having an oily build up from this, coating the inlet to the turbo, and generally throughout the intact tract. Some people fit oil catch cans into to the PCV line and then carry that on to the intake pipe, others fit a breather/filter to it and have it venting to atmosphere.
So my question is this:- Is it better to have the Crankcase gases pulled through using the intake pipe method (with a catch can to "clean" the gases) or would there be sufficient pressure for the crankcase to vent itself i.e using the breather/filter method?
Thanks,

- just realise this is probaly in the wrong section. Sorry :oops: please move accordingly
