Experience a cam failure? Me too.

Yes the shop checked the spring pressures at bith open and closed. rotella 15w40 was used up until the most recent oil change (approx 2000-2500 miles ago).

I strongly disagree with you about proper break-in. A little reading material for ya...

the STP has ZDDP in it. Look at the back of the bottle... It is the first ingredient

No, I don't think you do. I was talking about the comment regarding break-in on new engines- and they are all rollerized.

Believe me I know plenty about break-in, currently running a .600 lift solid flat tappet and double springs with damper.

OHHHHHHH! Nevermind then...here's me shuttin' up.:doh:

Hmm.. to make matters worse the post I was referencing isn't even on this, but the co4x4 board, that'll confuse a guy.

I hope you get it figured out, this stuff is the pits. I had a somewhat similar problem, but mine was the plain journal cam bearings- gone in 100 miles in my 401. Lobes were still good. I was considering Velcro motor mounts.

It's all good.
As much as I enjoy turnin' wrenches, this time aroundit ain't fun. It could have been a lot worse I suppose.

We then pulled the pan and once again I was expecting a thick silvery coating on the bottom. While there was evidence of metallic dust/oil it was not nearly as bad as we thought we'd see. YES!!!

If you still have it, cut the old filter open. Racers do it to check what's not going to the pan - a standard 10 micron filter does catch a lot. It's what you want it to do.

I'm experiencing a collapsed lifter from carbon grit lately. Next change I'm opening up the filter to see what's in there.

At work we use a cutter like this. I'm not saying to go out and buy one, you could probably make your own, like we did, for alot less. Just don't use a saw and add a bunch of metal as you cut.
