block damage
I broke out a few threads on the hose fitting on the block and wonder if other people have done the same and what they did to repair it? And can someone tell me what thread that is as maybe i can tap it deeper? thanks,Ray

Are you talking about the oil cooler lines?
If so, and IIRC, they were installed with a specific threadblocker that is apparently stronger than aluminum. I believe the current fix involves removing the connection and cleaning all the old threadblocker out of the threads. Reinstall using JB weld on the threads. Allow it to cure before threading the oil cooler lines onto the block.

Wow! I've not seen damage quite that extensive in that location. That is some kind of tough threadblocker.
The bottom hole is not too bad. You should be able to clean those threads out and use the JB weld fixit method without any trouble there.
The top hole presents problems since half the hole has no threads any longer. My thoughts are to find the correct size and pitch and further tap that hole so that you can have something to thread into. You are gonna need 4-5 threads. Next, I would take the adapter that got unscrewed out of that hole to a machine shop and tell them to make you a copy except with a longer threaded portion on that side. Screw the new part in with the JB weld and the washer and let it set up. I think you'll be fine.
Someone else may have some other and/or better ideas?

I just found the thread on the DFW block damage. It was back in 2010 and to my knowledge is still fine. While searching I found several threads on damage like yours and successful repairs. Do a search and reach out to several that have done it before. Like our situation I think yours can be saved.
