Hi
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.
Thanks

ive seen this happen in cars usually a lifter sometimes it just happens other times human error other times parts didnt work together for whatever reason sucks for your pocket book and hope you caught all that metal in the filter before it damaged anything else
good luck
