Ok here is my problem, I ran sea foam through my engine and ran it about 50 miles and changed the oil. I ended up using synthetic oil, which was just plain dumb. I should have known better than to put that into a 24 year old car. After three weeks of driving the engine is leaking oil in many spots, bad gaskets all over, leaking by the exhaust, balance shaft seal, cam tower and probably more places too. Hopefully not internally. The lifters are clicking, engine is running rough (shakes the car at idle). Basically the engine turned into a fountain spewing oil (ok it’s not that bad, but still...), there's a pond on top of the flat surface part of the engine. Lost about a qt of oil in 40 miles running under 2k rpm.
Only thing I think I can do it change it back to reg. oil and hope it seals back over time. No oil in the coolant, I hope there's no coolant in the oil, I'll find out soon. The engine sounds just like this:
YouTube - 944 Turbo Lifter Noise or Rod knock?
Sticky lifter? Just seems odd that it would stick after synthetic oil and sea foam unless something clogged it. Should I put sea foam into the oil and run it before I drain the synthetic oil and put the reg. oil back into it? Hate to put it away for winter already. Any ideas where I should go from here? Lesson learned... Never use synthetic oil in a old engine
Thanks guys
