i'm sure that when you rebuilt the engine that you used assembly lube on the camshaft
lobes and rocker arms. but did you pour oil on the cam-rockers just before starting?
i ask this cause as the camshaft turns it dips into the little puddle of oil standing in the
pockets under it. and also did you add any break in additive to your oil.
breaking down the rocker assembly is not hard and make sure to clean out all the little
passages that supply oil to the rockers. a rifle bore brush and welding tip cleaners work good to do this.
after rebuilding adjust valves hot and make sure the timing is correct.
Yep assembly lube on the cam lobes and 1 qt of oil over the rockers before startup. I did not use any additive only dino valvoline 10w30 per EB recommendation.
I rebuilt the rocker assembly a few weeks ago with reground rocker arms from 22re performance. I am just waiting on the head to arrive to button it all back up. When I called to order my head Jim said that the valve burn was most likely due to the valve seats settling in the EB head since they use a softer seat.
What additive and break in oils would you all recommend?
