2.3 Oil pump parts
Tuesday, September 28, 2010 1:58 PM
It seems that most of the parts are discontinued from GM.

I know the oil pump is Melling M136 and pick up is Melling 255S.

Im having a problem finding the pump drive gear...

The windage tray can be purchased from GM Vintage parts but the dealer I called said they didnt show any stock of drive gears. They did how ever have like 126 windage trays for $27.36.

Where else have you gotten the drive gear if you have recently done the swap?

Anyone have an extra they would like to part with?

Pretty sure thats the phenolic drive gear on the pump not the steel crank gear.

Bringing back an old thread, but Autozone is saying they are out, but I just ordered one from O'Reilly's website for $52.99.

When I bought the drive gear from rock auto, the lady said it was the last one they had in stock. She also said she wasn't sure if they would be getting more
