SO after doing a major Eng service & re-seal got the car back together & upon installing
the eng bay shift rod look up & see...a drip.
After inspection looks like the front oil galley plug.
Considering replacement "in-car". Anyone BTDT?

Pull the plug and tap for 3/8 NPT and plug.
Trick is go slow, grease the drill bits and tap. Stop, clean, grease often... rinse, wash, repeat.

Oh yeah....the engine needs to come out.

No, this is the approx 1" one at the bottom nearest the Taco plate.
I thought if I removed the Eng bar & motor mount Id have enough access
to avoid dropping the motor .. perhaps not.

I don't have an engine case handy to look at but I believe the plug you describe is for the oil pick-up passage. Which means it is not a pressurised oil galley.

You might be able to access it with the engine bar out but it will be limited access.

You are probably best off pulling the engine.

You might be able to do that one in car, it's a 8mm key threaded plug. try to remove it, clean and reinstall with a sealant.

Worse case scenario, the key strips out, I'd do a spotless cleaning and rough it up then use an epoxy like hysol or JB weld to seal it from the outside.
This is commonly done as part of a /6 engine rebuild.

So.. faced with engine R&R ..again, I thought this was worth a try.
Its interesting that after YEARS of owning & working on these cars I still find things I've never tried.
Droppd the bar removed the heater ducting on the drivers side & the motor mount
to get at the bugger. Sure enough if there was ever any sealant on it, it was gone now.
Also interesting that not all motors use that metric threaded plug in this location.
It took a couple of days for the 1st drip to show

Do you have enough room to drill and tap? Easy place to minimize shavings penetration to unwanted places and clean up.

I see that the plug was already replaced in the past. Just unscrew, clean, sealant and back on.
