Hi-
My 95 GC with the 4.0 liter is making interesting noises. The best way to describe it is that it sounds like a diesel. It's not super loud, but it's definitely got that diesel "knocking" sound.
I have recently run some engine flush through it and changed the oil. I did the flush because I changed the exhaust manifold a week ago, and after looking inside the intake manifold, and also checking under the oil cap, I saw a LOT of crud build up.
So, anyone have any thoughts on the diesel?
