Thread: Lifter Stuck / Push rod loose

Tweet

I don't think there is any question you guys called it exactly. That Camaro I bought a few years ago had one lobe gone and the lifter was reshaped considerbly. I found lots of shavings in the pan, so that engine came down to a bare block to get scrubbed clean before going back together. You should have seen the metal on the oil pump screen.

Change the pump while you have it apart too.

I ended up pulling it out from the top. The bottom of the lifter is not flat like all of the other lifters..it is somewhat rounded inwards. I could not visually see, or tell by the touch of my finger if the cam lobe is worn...When i replaced the rounded lifter with a flat lifter, it went up higher and did not sit down in the bore. After cranking the engine over, i measured how high this lifter was rising compared to others..it was about 1/32" lower than all of the others..is this bad? Is there any other way to check the lobe without pulling the cam out?

Thanks for all of your help.
