Have some pictures.

1. Front of oil pan the scratch is about 1/2 inch long, no dents in the pan and the pan appears to lay flat on block.


2. No. 1 rod cap was scraping the bottom of the oil pan, there is a shiny mark on the rod cap right side and almost center on the lip


3. No. 1 on the crank has a raised ridge in the center. It going to need machined.
I pulled the No. 2 rod bearing cap and it looks much better.


I did hear thumping noises after the engine & the Hydra-Matic got warmed up. I always thought it was the Hydra-Matic making all the noise.

Will post more as I disassemble the rest of the rod caps and get the crank machined.

Thanks for all the input. Michael...
