Comp cam warranty
Comp is crap.
Could have went flat from numerous things... just one lobe.. check the spring pressure, that the lifter spins , coil bind.
When you dont catch it right away.. you can't just say it was a bad lobe till you check the above. If you do catch it right away.. with all else correct..it will show as porosity near/at the peak of the lobe...either a issue with the core or hardening process
