Yeah, I've noticed the same thing. Kinda hard to tell from the drivers seat
exactly what it is (fan or exhaust or even the cat). I've only noticed it
when the engine is cold, but it doesn't do it every time. BTW, mine is a V6
so it's not just the V8s.

-- My '96 has had a pinging noise that shows up during acceleration, no matter how hard or easy, since I bought it. There is less with 92 octane gas, so I use that. The truck just turned 5,000 miles, and the dealer tech said it might be that the exhaust gaskets really seal and last, but the engine might not be broken in, or it could be timing chain noise. Well, my friends '98 Ram 5.9 doesn't do it. He said there is a TSB on the 3.9s for detonation, but not for the 5.2s. Strange, they are basically the same except for 2 cylinders. I'll have to take it in on a day off. It seems to be getting a little less, but I might just be getting used to it. I'll pass on anything I find out. ---------- David Brown Mailto:dbrown@mh1.mcis.uchicago.edu
