Dennis,
Someone on this BBS (a big engine diesel mech?) mentioned that you can check for engine wear problems by analyzing the oil. He said it was very accurate, and could determine precisely where the wear was coming from (based on metal analysis).
So, those with really loud engine rattle might want to have their oil checked at the next drain interval. If there is truly no abnormal wear in the pistons/rings/cylinder walls, such a test should show that to be true, no?
If it turns out to be very expensive to do, we could perhaps start a donation fund to have such an analysis done on the worst sounding cars. My car does not (currently!) make that much noise, so I'd be glad to be make a donation (Paypal, etc).
I just took my Bullitt in to have the transmission looked at again (it's leaking after the shift fork rebuild, still crunches in 2nd while cold and 1st while hot). I also mentioned the detonation on 87, light ping on 89, no ping on 91 (but sluggish), cold engine rattle (2000-4000 RPM), driver's side front wheel bearing leaking, plastic brake resevoir leaking (seaping), slightly warped front brake rotors (I'm guessing caused by improperly torqued wheels), a minor rattle in the cabin, still present wind noise (2nd attempt), removal of StarGuard and replacement of associated panel (holes).
I told them not to do any work on the engine or transmission without contacting me first (I got this in writing). I had hoped the engine rattle problem was not piston related, but it appears that it may be the culprit. I had speculated that if it were piston related, we might see extra oil consumption. At around 1800 miles I had checked my oil and there was no noticeable oil use. After many attempts to isolate the engine rattle sound (inducing the sound intentionally), I measured my oil level at 2552 miles and it was a 1/2 quart low. 1/2 quart in ~752 miles. Cr*p. Hope that's just coincidence (I measured it very carefully both times, under the same conditions).
So, if what the Ford engineer says is accurate, is this indeed piston slap?
