Thanks for the info.
The sound is almost like a deisel motor sound, only a whole lot quieter than a deisel; like rolling marbles around in a wooden box.
I've heard my share of bad connecting rods and I know what they sound like when they're getting ready to let go.
This sounds kinda more like a well-broken-in tractor motor.
Never heard of wrist pins rattling as a normal thing. But I'm in Chevy territory now and eager to learn.
I just want to treat the truck well and get the most life out of it I can without blowing it up. you're thoughts and advice are much appreciated.
