PCV question

[derK]

ok, on my attempts to install my MAFT in blowthrough, and to eliminate my accordian hose, i have an idea where to source for my ISC, but i don't know what to do with my PCV tube that connects to the accordian pipe, up to the valve covers, and into the intake manifold........... Can i:

a)just completly cap it off on the intake manifold
b)run some sort of catch can
c)just put breathers on top of the valve covers.

what is the best way to do it??

best bet is to run some sort of catch can.

you can cap off the accordian and the tb. run 2 heater hoses off the valve covers to the bottom of the engine bay. problem solves.

lol i don't want to do that......that's bad for the environment....plus i'll always think i'm leaking oil

Bad idea, yeah the bottom of the car will never rust, but you will end up with a nasty grimly mess under it in a period of time. Not to mention that as the motor wears and you get more and more blow by you get more and more or a mess. Also if you live in a state that has inspection, then it has to be routed back to the intake for two reasons, first is emission, and second is safty.

no it doesnt have to be right under the engine itself it can be routed a little further back. I know of alot of supra owners that do this. no inspection here but really how hard is it to change it back when inspection time comes? Just as easy as popping out a test pipe and puttin in the cat. It wouldnt do more harm then that. Also bad for the enviroment it maybe but you're not the exxon Valdez spewing out gallons of oil a day. The bottom of the car wont be as bad as you think. Even tho a regular car wash can help(automatic ones that clean the underside) and I go thru some from time to time to do just that although i do have a catch can. Hopefully as the motor wears you wont be getting alot of blow by. If you are then you're not doing so great with regular keep up. Also if it looks as your leaking oil out of this then you got alot of blow by. if you run them to the right place then you'll know its not an oil leak.
