okay, this motor is kiling me. we tried for a week to get oil pressure and finally did, we went to do startup today and we ran it for the 30 minutes. things went well quite a bit of oil smoke but that was more from when it got stolen and they blew oil everywhere. Anyway, there was a noticable lifter tick especially at idle after the 30 minutes. anyway, pulled the valve covers and noticed that the drivers very rear rocker was not moving much at all an on the non lobe side of the cam the rocker was very loose, I mean it was really loose. checked the rocker assembly, the pushrods and everything checked out. Okay great we wiped a damn cam..... no that does not seam to be the case yet. We pulled the intake off and pulled the lifters and here is where it gets interesting. instead of the very slight crown on the lifter the drivers rear was indented at least .030" (kind of hard to measure) it looked like it was hit real hard but the rockers pushrods and rest of the valvetrain look great. ANY IDEA WHAT COULD CAUSE THIS? it is a 212/212 cam with comp lifters and I am leaning toward a manufacturing defect.
so now for more questions, if the cam is okay can we just throw a new lifter in and go from there? do we have to do the cam breakin again? should we replace all the lifters or just that one?
if the cam proves to be bad how much cleaning is there to do, the oil looked clean (there was cam and assembly lube in it but no noticable metal shavings) do we have to pull the motor and all the bearings, crank, pistons, and clean all the passages or is a few oil changes with a few (20-30 seconds enough to get pressure to the rockers) seconds of cranking with the new oil enough? Help me here!
sorry this got long winded I just wanted to give as much info as possible. let me know what you think.
