I am getting ready to do some engine work on my 85 GL-10 and one of the things I will be replacing is the oil pump. Just trying to see if anybody knows of a place that has a great deal on one. 1stsubaruparts.com is around $93 and change.

You sure it needs to be replaced? I'd just throw a new shaft seal and o-ring in it and call it a day...

 

But, last time I checked, the complete pump assembly was well over $100... maybe I'm looking in the wrong places?

My local source that used to be about $60 has bumped the price up to $90 or $95 last time I checked. So that's about the going rate it seems. There's only one manufacturer (the OEM), so you are kind of stuck as far as price goes.

 

If it's really worn, you might consider resealing another used one. They usually last quite a long time unlike the EA81 pumps. The original on my 86 sedan still puts out over 25 psi at hot idle (800 rpm) even at 231,000. I did reseal it when I did the head gaskets and cam tower o-rings. And I have an aftermarket mechanical guage in the car, so my readings are accurate. It will do well over 100 psi when reved cold.

Personally I just like to replace them when I do all the front end work on the EA82 engine. Never knowing the exact amount of use or abuse it has taken over the years I just asume I start out with a fresh one. I feel better when it is a new part.

Illogical. There's procedures to verify the pump is within spec in the FSM. I don't know a single shop that replaces or reccomends replaceing EA82 oil pumps because it makes them feel good...... That's what feeler gauges are for.....

very few oil pumps exhibit significant wear, resealing them has always worked for me. but i have a new one in mine just for giggles.
