hmm. i was tearing down one of my heads and noticed the cam had machined itself into the front
 

bearings. wonder what would cause that, oil starvation?

Eyes opening...WIDE: BTDT. (TPIWWP)

not good. exhaust cam? looks almost like there was a balance issue on mine and it ate into the
 

bottom bearings.. has both cam followers jammed in.

surprisingly enough though the cam itself looks good.

running to the garage for pics now

Ummm - oil starvation would be a "not likely" -
 

Oil starvation and metal to metal contact would lead to friction induced heating - ceasing being more likely - rather than the cutting of metal.

Yep, exhaust cam snap. Learned my lesson for buying an engine on Ebay... It made 445whp though;)
 

Bent cam? Are you the original owner?

nope, picked the pair up for $25 off the guy who sold me the 2.8.
