I own an '82 w/ 45,000 miles. It is my every day driver and has given no problems for the year and a half I've owned it. I have the engine flushed and the oil changed every 3,000 miles. 2 days ago it started leaking oil...BAD. I took it to the place where I have my oil changed. Oil was spraying out from the oil filter gasket. They removed the filter, found it "clogged with sludge". They offered no explaination for how something like that could happen. The manager could only offer.."there's got to be something wrong with your engine". Is there anybody out there who's experienced or heard of something similar?
