I finished my 2f rebuild a little while ago and went to do the break in. After about 10 minutes heard a screeching sound and then the engine shut off, we pulled the motor and found the culprit to be a spun rod bearing.
Took the engine back to the shop and got the crank re-machined, everything else seemed fine. In the process saw that the front main didn’t seem like it was getting any oil either.
The machine shop has no idea what caused it. We blew out all the oil passages and they seemed to have good flow out the others. I’ve talked to a lot of people and no one really knows what it could be. So I’m throwing it out to the internet. Any advice on what I should do to test it on the new assembly? I’m ready to go again, but don’t want to have the same result, especially when I have no idea what caused it.
