i was thinking about that roz, and i have come to the conclusion that its because every rod knock i have ever heard has been on a car old (like 80's old). no sound insulation anywhere on most of those older cars, and that damned astro was no exception...
i still dont understand why you cant drive a contour with a rod knock though,i have driven cars with rod knock, and other than a slight performance decrease and a loud noise, it wasnt that bad.
oh and roz, if a mpotor has synthetic in it, wont that quiet the noise??
and damned if my dads old ramcharger didnt run forever with rod knock. i kept expecting it to go any day...last i saw it it was getting a new motor at 273,000 miles, after 100,000 miles of rod knock.
there has to be something about these newer motors (maybe the material they are made out of???) that keeps then from being at least driveable with rod knock.
