Hello all, hoping for some pointers on a strange issue with oiling. My brother just rebuilt the bottom end on a chevy 250 inline 6. Had the crank turned and plopped in undersized bearings the machine shop supplied for him. I had him check the clearance just to be sure and all checked out. Re-sealed the engine and now it's back in the car. He didn't mess with the cam, lifers, or pistons, just shaped up the crank. Everything else stayed in the block. Important to mention that he had the engine upside-down on the stand for about 2 months before he could get it back together.
Last night we were going to fire it, but I wanted to prime the engine first. In doing so, we got no oil at the rockers except #3 intake which was going like a champ! I have never seem this before and idk what in the world could cause it to only pump oil to one rocker. Any ideas?
