How did you damage a cam with zero miles on the engine?

RalliartRsX · 09-29-2019, 05:09 AM

Lack of oil pressure can quickly damage a cam bearing within secs of just startup.

Well then i guess it be fare to say this motor would need tobe dissasembled and fully inspected for damage.

Was the reason for the abnormal cam wear ever found?

^^ Yep. This will need ro be disassembled if it hasn't been already (especially to check the bb in the crankshaft as debris tends to congregate in that area and get throw into the engine on next startup)

I will tear it down to do further inspection. I dont suspect any damage because engine oil was primed before start up. The only damage is on 1 exhaust cam bearing. It's not damaged due to oil starvation looks like something got caught up in there. I will post pics after further investigation.
