Thanks. There is no oil on the plugs. I don't want (really cant unless no other way) to buy 12 rockers etc. I am pretty sure the head was done I just dont know if the rockers were replaced. I guess I just missed the part# on them. I drive 150Mi per day and I think it is getting worse fast. I was hoping I could just buy a cam and throw it in with 1 rocker on the badly worn lobe. The car just runs like a dream besides the tap. Seems you have to know if the rockers gears and all have been changed to know if the cam will fit.
