Re: Finally fixing it
really? It looks like the original has a direct route for the oil to
take. The aluminum one seems to block the oil more. I guess the first
thing I need to do is figure out why I get oil in the air filter :-).

Re: Finally fixing it
Think on where the oil is coming from inside the engine. It comes out
the top of the rockers via a hollow push rod. The rockers then fling
the oil up at the valve cover.
The baffle on the stock one picks up air down near the head, the Al one
picks up the splash at the top.

Re: Finally fixing it
That makes sense...
I'm afraid to ask this question... When I have the PCV breather out, it
looks like smoke or steam coming out of the hole. I know the PCV valve
works (when I take it out of the valve cover and put my thumb over it
there is a strong suction). Should anything come out the PCV breather hole?

Re: Finally fixing it
That makes sense...
I'm afraid to ask this question... When I have the PCV breather out, it
looks like smoke or steam coming out of the hole. I know the PCV valve
works (when I take it out of the valve cover and put my thumb over it
there is a strong suction). Should anything come out the PCV breather hole?

Re: Finally fixing it
Well, yes and no, mostly no.
The PCV or CCV systems are balanced.
Basically that means that the flow rate on the PCV suction should match
the intake from the air filter and a little extra to suck fumes.
If the cover or the grommets are leaking or if the breather hole
suddenly gets 1/3 bigger when you pull the fitting out or the charcoal
canister purge line hooked to the PCV line purges at idle, the PCV or
CCV gets overpowered and can't suck enough to do it's job.
This leads to oil blowing into the air filter. I just noticed I have to
do the CCV plastic line again on our Cherokee. There is oil dripping
out the bottom of the air filter box again. I did mine a couple years
ago and the CCV is just a tiny hose that plugs easy.
I described in another post to you how to check your canister purge.
