300x Valvetrain question

976 Views 6 Replies 5 Participants Last post by  SlammedRanger
We have a 2009 300x race engine with a high lift and long duration cam and aftermarket springs in it. It has worn away one lobe on the exhaust side and worn a deep section away on the rocker. I don't think its short of oil as the inlet lobe / rocker arm is ok.
Any reason for this.

Definitely an oil issue bro I dont care where it was built. having hardfaced rockers isnt going to prevent your situation from happening. a softer rocker isn't going to wear a cam lobe unless IT IS DRY. But defintely sounds like you need a new cam and rockers. Keep us posted.
