Hello, I am new to Buick engine rebuild s and I’m almost done with the 455 I’m putting together . while priming the engine to pump the hydraulic lifters up the pump seems to have a good amount of noise and vibration that can be felt through the drill turning the pump, I have not noticed this noise and vibration priming Chevy engines which also have a spur gear type pumps , I might be making to much out of this but it is more noise than I expected. The front cover and pump are TA pieces that were running on this engine before I took the engine down for rebuild.
Thanks
Thanks
