Core plug.

Did it today. Not the most awkward one but still hard to get to with starter motor on. Tried to take it off but couldn't undo bottom bolt. Started to round off so I stopped.
Managed to get long screwdriver in to hit the plug after removing the washer bottle. I then remembered why you should disconnect the battery prior to starting any work. Dropped the screwdriver onto the +
of the starter and nearly welded myself to the wing. . Anyway with a large socket, uj and long extension, I managed to get it in. The old one was badly rusted and wafer thin. You can just see the pin hole .

I need to do the V8's core plugs sooner or later.

None leak but tits only a matter of time!!

Stag well seal is my sealant of choice,.
