Evening All,

I have a 96 Sport with the GT-40 with EFI. While winterizing, I managed to strip the threads out of the "block" on the Starboard brass drain plug. Not only are threads gone in the block, the threads are pretty much done on the plug. Has anyone done this before and how do I fix it.

Thanks

Drill and tap to 3/8 NPT.

Wow, that was fast, thanks. Any idea where I can find the new brass plug. Can I assume I need a brass plug?

McMaster Carr sells brass pipe plugs Another alternative could be to use a Stainless Steel Hex Nut Expansion Plug for 7/16 Pipe Size $6.87 Each #2599K27 (tap drill size for 1/4" pipe is 7/16")
I recommend using Petes answer, but not everyone has access to or knows how to drill and tap a block with the engine in place.

Keep it as original as YOU want it

I would run a 1/4" npt tap through the hole first, the tapered pipe threads may allow you to save it without upsizing. Any hardware store will have the plugs- go with brass.

I like the way Tim thinks, definitely worth a shot, it's worked for me and at other times it hasn't Nothing to lose doing this first.

I too like the idea plus, brass male fittings have a tendency to run oversize so with just chasing the block, it may work.
