Hey all!
Wanted to see if anyone here had some input on an oddity I'm facing.
Before starting my engine I noticed the engine was extremely tight and couldn't be turned over by hand.
Long story short I narrowed down the problem to connecting rod and bearing #3. Plastigauge was showing at .0008 which is out of tolerance by a little bit (.001 - .003). The crank had been turned down so I thought to myself that maybe they forgot to hit that one. Checking it with a micrometer vs the others and it's identical.
Here's where it gets screwy... I checked the cap and the rod sides with a micrometer and bore as best as I could and it doesn't seem out of round at all from any way I've checked it. But as soon as I tighten that rod down to 30-35ftlbs with the oversize bearing in, the engine gets incredibly tight.
Is the difference negligible enough that the engine will still fire and run like this? I don't want to chance throwing a rod.
I've heard of guys taking emory cloth to the back sides of the bearing but I'm not sure how I feel about that.
What's more, all my Googlefoo has failed me and I can't find a place to buy a brand new connecting rod for this engine.
Any input is welcome, thank you!
