Okay, I am doing om617 turbo swap and in the process I removed my oil pressure sending unit from the bottom of the oil filter housing which threaded in horizontally. well months have passed and now I can remember what sealed it to the housing. is it a copper washer or o-ring. I seen in an parts diagram the pressure sending unit is #266 and the seal looks to be #269 but it does not give a description. anyone?

thanks!

Seal Ring 12 X 16 X 1.5 mm

is it just a washer? steel, copper, or aluminum?

thanks.

Usually, seal rings are made from a soft metal, such as copper or aluminum.
