00 STS is slowly leaking oil. I assume it is contacting the exhaust manifold as I can occasionally smell burnt oil. I took it to Cadillac for an estimate and they want $2600. The explanation I received is that the it's a big job because the tranny has to be dropped, etc. To the credit of the mechanics rep, he told me it wasn't worth spending that kind of $$ at this time and to just continue to monitor it to see if it gets worse. It doesn't appear to have changed much over the last 6 months. I do notice that it leaks more when it sits idle for any length of time. I had a similar problem with my 95 STS and 88 Deville. I've talked to a co-worker who has experienced similar problems with his 98 Deville. Is it common for most Cadillacs to experience oil leaks? My co-worker as well as my brother said they were able to eliminate the leaks by using an oil additve that is supposed to stop leaks by "filling in" the gaps between the seals. Has anyone experienced success with an additive? If so, please tell me what you used. Thanks.
