Oil plug gasket

[CurtB]

Anyone know what size washer/crush ring goes on the crankcase oil drain plug?

Picked one up this weekend for my oil change. I can measure when I get home but plug itself is M18x1.5 according to NAPAs site.

Mine is 12mm. I’ve read that replacement oil pans use a smaller diameter drain plug than the original.

Now that you mention it I remember reading that somewhere too. Think it was difference between years (60/62).

You should use the Toyota gasket. Any dealer can get them for you.

There were changes to the 2f pan.

So that statement right there is saying you purchased a new oil pan. The new updated pan is different than the old pan.... And it requires a different gasket than the old pan.
It also has a smaller drain hole than the original pan, requiring the smaller drain bolt and gasket.

New updated oil pan: 12101-61013
Gasket for pan above: 12151-61011
Drain plug for above: 90341-12012
Drain Plug gasket for plug above: 90430-12028


Old (wrong) original oil pan gasket: 12151-61010


(in a pinch 12151-61010 can be used successfully if it's mounted perfectly with a little Toyota FIPG. It will crush down and seal)
