I want to make sure my engine builder didn't forget a freeze/drain plug. This hole is next to the oil filter bung. It is not the engine mount hole. Is it just where a plug/bolt goes that holds a bracket/ground on the block? I might have a baggy labeled for it but I figured someone might know offhand.

Also, does it go into a water jacket/oil galley or anything?

Thanks

Yeah it is threaded. There is a similar one on the passenger side that a bracket gets stuck to. The more I think about it the more I think the neg. battery cable goes there.

Are you talking about the threaded hole where your oil pressure sender goes?

I dont believe my 93 had that. I think the sending unit threads straight into the block.

That is strange. I thought all 302 blocks were the same.

Yeah, the 94-95 Mustangs had one threaded straight into the b-didn't know the 93s did as well...but the threads are the same-if the log type didn't thread in, there's something wrong.

.....rod going in there. This thread has me so far in the gutter I can't stand myself

Edit: I guess to keep on topic, my 93 did not have the long hexagonal piece, but rather just a sender coming right off of the block. Just get a Sport Comp oil pressure gauge and a steel braided line and forget it. Don't use the nylon line that comes with the gauge....scary

I just snapped my sender in half trying to get it in. On closer inspection it looks like there is some petrified rtv on the threads halfway in and my tap&die kit doesn't have the right size to clean the threads...

I thought the machine shop would take care of these things. They charged me a lot too...

Long hex hollow rod, NPT threads. Ford service manual doesn't show it.

Sorry, but what are you saying the long hex hollow rod is for? To clean the threads? I ordered a 1/2" 18 tap for the hole.

I really don't want to strip the block.
