Grinding, " diesel " noise under valve covers

Nah, Brother, No Way on that!!!!!!! Now about the Lil bits O' Copper? Ain't that inner bearing material? Or am I still wacked? I don't think that's related, but I'm a lifetime Carpenter, not a Lifetime Pro Mechanic

The copper material in the bearings is on the bottom. It would have had to wear through two or three layers of metal to get to the copper. There'd be a lot of metal. There's not. It could be anything. Every single engine has minute amounts of metal in the oil. Normal.

First thing I thought. My dad has a GTX with a 440 in it. The motor was built years ago, I'm assuming with TRWs in it. Sounds exactly like his video.

Well, My hearing is terrible, I admit. But what "I'M" hearing sounds like piston slap. That's the problem with being online. You just never can be 100% sure.
