850 Turbo PCV system & rear main seal. Experts?? 850

posted by  someone claiming to be Leon on  Fri Jan 13 01:41 CST 2006 [RELATED]

Hello all,

I have a 1995 850 Turbo and the rear main seal has been leaking for some time (pretty badly). I finally plan to replace it this weekend, but I'm wondering if the PCV system is up to par as well. The car has 141k miles on it (I have owned it from 102k and have always changed the oil @ 3k). Anyway, I tried the old test from the 240 and 740 days of removing the oil cap with the engine idling. The cap sits still (doesn't really suck down, but doesn't blow off either). I know this car doesn't use a flame trap, so I'm wondering what else I should check into (I tried a search on here, but all of the found posts were dealing with non-turbo 850's with a slightly different PCV system). Should I go ahead with the seal replacement, or will the new one leak due to PCV problems? As I said, there is no pressure in the crankcase (no dipstick blowing out or oil cap leaking). Any help would be greatly appreciated.

Thanks,

Leon
