Camshaft lobe chip - how did this not destroy my head?
Ok a bit of a strange one:
Im returning a motor to stock and pulled a set of 264 HKS cams from the head to sell. I had a buyer and while packing the camshafts I noticed a chip on the intake cam:
Heres the chip next to the bucket:
These cam of a running and driving car with no issues. My question is how did this not cause more damage to the head?
Had enough surface area on the un-chipped area to not be a problem.
I wouldn't push it any further...
I'd probably chuck the shim that was riding on as well.
Sounds like its time for a magnetic oil drain plug! Good news is if it came out in one piece it probably won't make it through the oil pump screen.
but if it came out in a bunch of smaller pieces...
I had kind of the opposite problem and I found a chip in one of my shims after I did engine break-in, though cam looked perfect. After shitting water for a while I replaced the shim and kept an eye on the magnetic drain plug. I got what I'd consider a "reasonable" amount of swarf on the magnet and stopped worrying about it after that. Both new shim and cam still look good. sorry about your fancy HKS cam though, that's a bummer. :(
