PN-Request: Oil Pump 91T

2restomod · 03-24-2008, 02:34 PM

Evidently there are two part numbers for the 91Turbo Oil Pump? I was at the dealer getting a seal O'ring and they told me there were two different oil pumps for the 91 and that a change took place in Mid or Early 91 on the oil pump #'s? Can anyone confirm this?

Correct. Looks like a very slight change judging by the part numbers. I'm not sure if they are interchangeable or not. If you send me a VIN I can check which one you need.

15100-88381 - 90/01 to 91/05
15100-88382 - 91/05 to 95/06

^Thanks. I already bought the pump some time ago for my rebuild. As you can see from my post on the Turbo forum I'm trying to figure out why there is a little (tapped) hole to the right of the crank? After the rebuild I had a small oil leak that I was trying to trace down. As near as I can tell this is where it was coming from. Near as I can figure it is the wrong oil pump, or there is something that goes in that hole that I don't have? When I went in to the dealer to get the seal (where I originally thought the leak was coming from), they didn't have either oil pump in stock so I could compare them.
Any idea of why the pumps were changed, or what the difference is? Again, thanks for your input!
The VIN# is JT2SW22N3M0015697
Found the receipt for the oil pump---Part #015100-88382

OK, just checked with the dealer and they confirmed that I have the wrong oil pump. I should have the early one and instead I've got the later one.
So, do you guys with the later date 2's have a timing pointer there or ?
The guys at TMS are telling me to just put a 10mm bolt in it, like someone suggested on the Turbo Forum.
