Customer brought me a GA case to do a performance bug T4 DTM conversion.
He was going to DIY the job, till he fuched up and drilled the wrong place thinking he was doing the oil galley plug job. He chickened out after this and is having me do the build.
I've already talked him into using a different case for the build, so no rush, but he'd like to save the case.

So he drilled right into the oil pressure relief area of the case, enlarging the port. I didn't want to use it for his build in case the piston cocks, snags, etc.

Could this machined OS and sleeved? some other method?
Or is he hooped?

Forgot the pics
I tapped it for a 3/8" plug, the hole he drilled was already this size so I couldn't have done it for any smaller plug.

3rd pic the pencil is pointing right where the relief piston sits.

Looks to me you are out of luck. Is the seat at the top damaged? I have 2 cases here one shows this galley plug looking spot. Is this a plug? It looks like a spot on the casting only. I may have a case if you need one

I would ream the hole. Add a solid pice back in, weld it up, machine it up, and be done. Problem is the impurities in the metal.

Oh course the man hours to do all that would be

The seat is OK but that "galley hole" is just shy of 180* round of the bore. not going to use the case because I know sure as poop it will bite me on the ass.

I have a case in stock for him, it's already prepped for a DTM conversion and the oil galley plugs are done right.

Try wet wipes ...

Gee thanks Andy... I think I'll use the other case...no wet wipes.
