Anyone know if there were any differences on the 85-92 vs. 93-94?

I´m Not Sure, but I´ve Heard Somethin´ About the Seals... I Suggest you to do the Search on the Forums.

Just for Info: I´ve just Installed a Brand New Oil Pump on my 1985 EA82 Wagon. Works Fine!

Tried the forum search. 3-character keywords don't work. Kinda hard when you just search for "EA-82 Pump".

I believe the oil pump shaft is a different diameter. The pumps should be interchangable though, as the blocks should be the same. I seem to remember putting an oil pump I had originally purchased for an 86 into a 92 last year with no problems.
