What do the tips of the pushrods look like on both ends? Can you post photos of the pushrod tips?
Thanks Bob
Engine was up to temp and oil pressure is good (around 36-38 psi)
Here are some pictures
Pushrods looked evenly worn/shiny to me as did the mating surfaces on the arms.
I didn't remove them and check for straightness. I was worried that if I pulled them out it might be difficult to get them seated back into the lifter but I suppose that's not an issue?
I'll let you take a look at the valve tips and give your opinion. They looked relatively ok to me but this is the first Buick engine I've owned...
