Found my OE Oil plug in a box w/ other old bolts... I kept it because many idiots to similar damage to oil drains...
But first people need to understand how the drain hole are made in most stamped pans...
The hole thru the pan you see is just that a simple hole.
Inside they spot welded a thicker metal stamped "nut" that will allow oil to go between the parts.
then outside you have some type of seal & the plug. (Not all use a "pilot" plug that make it easier to start the plug in after draining.)
When tight only the seal keeps oil in the pan.
If the seal is wrong or damage, often will leak & damage the pan too because morons think just need more Torque...
Seals Like this...
I think maybe was metal inner holding rubber outer but rubber torn off 30 years ago & never replace & morons smash the middle
AND Pan metal to Cone Out a new shape & still leaked. Nearly rounded off the head to get that out.
They even tried RTV to seal @ some point as I cleaned it today to get a good pic & had a Booger stuck next to thread.
So 65274 metal/rubber gasket has the rubber in the damaged area & leaked. Other metal seals had similar problems.
I've tried Fiber "washers" too. Works but not as well as any Nylon.
This type of
is also why Dorman & others make/made oversize plugs because fools way over torque the plug & strip the stamp nut. Once upon time I seen 2x even 3x oversize self-tapper plugs available to "fix" this & other types of oil pans. They still make various rubber plugs like dorman 090-932CD to replace plugs w/ strip holes but some don't last long.
Is only "luck" that the pan didn't strip out... look @ second pic where one section of thread look worse that all other... & don't mean just galling on three threads.
