It sure sounds like a rod bearing has failed. This noise will keep you from selling the car or the value will be greatly diminished. Recommend you pull the pan and find the bad bearing. If the crank is not damaged or just a little scuff you can re-polish it with emery cloth. If you are lucky and the crank is ok you can replace the rod bearing on each piston and be good to go. I would check the clearance with plasti-gage and check a couple of the crank bearings which are probably OK. Driving it will damage the crank or cause a rod to fail and then you are SOL. Bummer

when i took it apart, i found the bolts sheared of the cam. The ends were still threaded into the cam and the chain did not even break.
the pistons had little smilly faces stamped into them, i did not.

Wow that is an unusual failure. Don't think I have ever heard of that. Got to be some reason the cam bolts and key sheared. The smiley faces would also indicate bent valves as well as possible cracked pistons. I am sorry to say this sounds like a bad failure caused by loss of lubrication (if the cam shaft seized). Sounds like the engine is toast. I am very sorry.
Let me know what you find out.

it is not as unusual as you think. it happens from time to time. It was not an oiling issue, I BELIEVE the bolts were not the correct grade, add my right foot into the mix and BOOM. yes all the valves & push rods were bent but the pistons were just cosmetic. I even fly cut the pistons to accomodate my custom built heads and @ 15k hard miles no issues, outside of a broken valve spring this summer.

Thank you simplec6 for posting it. I don't know why it didn't come up for me. So anyway that's what I discovered when I removed the cover. I couldn't believe how loose it was. Rodan I did buy the comp cams locking plate, I will hopefully get it all back together next week. Putting a cam in it while I'm in there
