I let my dad listen to my truck tonight. He's been playing around with diesels for years (that's what got me started), but he wasn't able to even hear the knock at first. I had to get him to stand back away from the truck at an angle in order for him to be able to hear the noise. So it's obviously not a very loud knocking, but enough of one that I'm able to determine that's it not supposed to be there. He said it sounded like a normal 6.2L to him. But of course, I've been driving this truck a long time, and I know each and every little sound it makes, and what is and isn't supposed to be there. [img]tongue.gif[/img]

On a side note, I was wrong about this rebuild being 10 years old. It was actually February of 1996 when I started on the 6.2L project. So it's only been 9 years. I guess memory is one of the first things to go! I'll be 29 in a couple of months....starting to get some gray hairs already!! Still, it's been 9 years and I haven't had to do any major repairs to the 6.2L yet!
