Help!! My '97 Expy became a diesel overnight!
I have a 97 Expedition, 4.6L. Recently, the engine started tapping/rattling like crazy. I got an oil change. They ran a cleaner additive through and gave me the high-mileage oil to help swell the seals. (It has about 185,000 miles, BTW.) That worked for a couple of weeks.
Now the tap/rattle is back. It sounds basically like a diesel engine. My suspicion is a timing chain problem. Any advice?
