Cam Problem!
You grinded off a lobe on your cam. Will the filter catch all that metal?
The problem with the all this cam problems? Oil is not what is was. Go to your local GM dealer, get a pint of their EOS engine break in lube. Use that with some cheap 30 wt, that will be fine, except that metal already in there.
Maybe it will be okay.
Did CoyoteJacks engine live through its cam problems? Didnt his do the same thing?
