190e 2.6 crank shaft and connecting rod bolts, do they need to be replaced?
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.

I think you are supposed to replace the con rod bolts but I can tell you I didn't when I had my motor apart about 15K ago. Granted it doesn't see a lot of RPM but it does take a beating with 18 PSI of boost. If your engine hasn't had them apart before I wouldn't think twice to re-use them but I would be hesitant to re-use them a third time.
