After buying OHHH so many new parts on my 1999 olds 88.. it was still running rough. A friend suggested replacing the plenum gasket, after examination revealed an air leak near one corner of the plenum. Ok, did that, but he forgot to replace the O rings..
so he RE-did that.. NOW it is blowing steam out the exhaust (I mean my radiator was full and now it is EMPTY) AND it has quite a bit of gas in the oil (it had some gas in the oil before the gasket change too). I DON'T want to do any further damage. Can someone please please give me some ideas to fix this before it gets any worse? Thanks in advance, Leah
