I am putting the engine back together. I picked up Three new complete bearing halves that are for the dowel pins in the block that go around the crank. With just the crank in place on the pins when I turn it by hand the middle bearing makes a noise that sounds like it is hitting something. Everything looks good. I can not figure it out. Any suggestions Thanks
Move the bearing and try again.
I even swapped the bearings and it still does it
Did you check the round out on the crank??
No I did not. Who can do that a machine shop?
Yep.
If your crank is F'd then no sense pursuing that issue. Oil all the bearings and upper and lower main bearings and drop it back on and see how is sounds/feels.
Thanks, I will work on it tomorrow night.
