engine noise on a fresh rebuild
I'm hoping that it's the cam and lifters. It mostly happens at start up.

Re: engine noise on a fresh rebuild
Your videos are unavailable to me, but my initial question would be what type of lifters do you have?

Re: engine noise on a fresh rebuild
hydraulic
It's very loud at start up but it seems to be slightly noisy through my entire drive. Also, when I downshift and the motor revs up, it has a noise to it as well. At start up it literally sounds like a spun bearing. |

Take your oil filter off cut it open and see if you see any metal in the filter.

Re: engine noise on a fresh rebuild
Which engine do you have? Does the oil pressure gauge work? Cold start up oil pressure after a few seconds on my 250 6 cylinder is about 50 psi with 10-30w oil.
A bad/worn bearing will lower oil pressure quite a bit.

Re: engine noise on a fresh rebuild
I took the pan off and inspected all bearings and they look great!
