I always have lots of condensation in my oil filler tube. T have removed emmisions as per the pratch tutorial. I found that one of the vacume lines that operates the purge valve has no vacumme, so therefore the purge valve never opened. So i ran tube from the oil filler neck dircetly to one of intake nipples. I found that this setup, causes a lean running condition and harder cold starts. Also when all intake manifold nipples are capped, the car runs, and downshifts, much much, smoother. So i was thinking, could i buy some sort of small electric pump, that suck out air from the oil filler tube without putting it into the engine, and leave the charcol canister system in tack. I was also wondering how people with aftermarket carbs vent their crankcases? Thanks for your time, Matt.

Ha, i guess its a bad call.

put a pcv valve in between the vac and the crankcase

How about just venting to atmosphere?

Run a tube down to the bottom of the motor and forget about it!

PCV valve in the line is a good idea as well.

Jeez, we go thru this topic like once a week. Matty, dont overcomplicate it. Either run it as per the tutorial, or do the PCV thing.

Kehoe- you cant just leave it open like that. Your oil will get the sludge in it. And your oil fill pipe will rust to hell, leaving bits of rust in your engine oil.

Thanks for the tip Carl!!! I'm using a PCV Valve. Thanks!!!

It's much easier on the SA models as the carbon canister is in the aircleaner lid. Just run a hose from the carbon canister to the nipple on the center housing and put a little breather filter on the nipple on the oil filler tube, then tee the tank purge line into the hose.
If you run a vacuum line from the base of the carb to the oil filler tube, you just create a vacuum leak as there is no restriction, but since the carbon canister is in the lid, the motor draws in vapors from the INLET of the carb which doesn't affect vacuum one bit.
A very slight vacuum is all that's required BTW.

It's now part of the FAQ. So now you can point someone there like once a week.

Wankelguy, your points on the SA models aren't covered very well in the links from teh FAQ, IIRC.

do you have any pics of the pcv valve instaled yet? if so send me some i have the same problem and need to take care of it.

hey, what if i reconnected my airpump, to suck the moisture and fumes from the crankcase. I think this would work, and it would keep the air out of the intake manifold

slashdawg00110

You only need a slight vacuum and I think the airpump would be overkill.

Micahman - I haven't installed the PCV yet, just using the purge valve like in the tutorial. peejay has talked about doing it. Maybe he has pics.
