Re: Micro Welding of bearing shell to rod housing bore
I've been reading this thread and wondered why no one mentioned detonation as being a possible issue.
It can show up in rod bearings.... Usually the shells just fall out....and might have some odd looking wear marks....

Fly poop on spark plugs? Fuel change? Verify timing and TDC marks? Try another known good timing light? Just reaching here. |

Re: Micro Welding of bearing shell to rod housing bore
If the engine is apart and obviously it is....
Look at the ring lands and the tops of the pistons for any oddball signs that usually indicate detonation. Pecker tracks on pistons, or on the sides of the pistons above the rings. Ring lands beat up.... If all is clean then you can rule it out.... It's not likely but I thought I'd throw it out there.
