I've read a little bit about similar symptoms but was unable to really relate any of them to my problem...
I have an 88 XJ 4.0 w/ AW4 and recently it has begun making that diesel sound under moderate to hard acceleration... It seems to do it on down shift at around 1500-2200 RPMs or so but goes away at up shift. I can romp on it at a stand still or doing 50MPH and it does the same thing... hot or cold, doesn't matter...
When the engine gets hot if I really get after it it'll burn a little oil... am running 33's and 4.56's and am getting 16-17 MPG on the highway (70-75MPH on 250 plus mile trip)... don't know if that's normal or not...
Any ideas?
