Oil pan in the northstar engins have defect the manufacturer is aware of and will fix in any unit under warenty or extended insurance programs. The problem is a structural weakness of the cast metal of the oil the oil pan is constructed....minute cracks develop in the metal around the retaining screws of the oil pan and excessive seepage is encountered causing at the least an environmental hazard. Owners without the above coverage are forced to pay extensive repair costs which should be born by manufacturer whenever the problem develops. I have a definite fear or reprecusion and do not want my identy or my vehicle identy made public.

Oil pan gasket leaking.....theres been a service bulliten alert put out on this in feb. 1996. My transmission was replaced in 1997 and the gasket should have been replaced at this time. Oil is leaking fairly bad and I was informed by cadillac mechanic that the oil going back on the exhaust system and the cad. Converter could caught fire. I'm trying to get cadallic to replace this gasket at their cost. They want to charge me $1500.00 to replace this $28.00 part. Any help you could give me would be greatly appreciated.
