300x Valvetrain question

968 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.

Sounds like an oiling problem, or a camshaft failure due to the harding process the cams go through when made,
Sounds like you are going to have to change out the cam and rockers, you should be able to order from the US and have shipped to Austrilia.
