~130K miles, 2.5L. First time having the cover off. Was starting to leak on the back side. New gasket went in with no issue. Have always used good synthetic oils, sometimes with AutoRX. Chain was tight. Drain intervals were around 5-7K miles each but doing 5k from now on.
There seems to be a "Z" pattern on the cam lobes. Is this normal? UOAs haven't shown any high Fe.
