I can't seem to find much information on the crankshaft and connecting rod bolts I am wondering if they need to be replaced or can I reuse them. I believe they are stretch bolds because the torque specs say that a 90° rotation is the last step.
I am also wondering if anybody has instructions for rebuilding the oil pump on the M103 mine seems to be improperly assembled from whom ever worked on it previously. I noticed that it had been over tightened to the bottom of the engine and because of that it was leaking right back into the pan! I was hardly getting any oil pressure!

Thanks so much for advice ! I always appreciate it.
