Oil pumps: rebuild vs OEM vs e21 vs e30 vs other

I am on the hunt for a new oil pump and in my searches most appear to have disappeared from the market.

http://www.bmw2002faq.com/component/option,com_forum/Itemid,57/page,viewtopic/t,377519/highlight,oil+pump+rebuild/

Anyway, the link above failed to get answers on a pump rebuild. Anyone know of a good person for me to send my pump to , including approx costs? It works well I am told, but in my rebuild I don't want to risk putting back in a 40 year old pump without at least a tune-up.

Any links on a new pump would also be appreciated.

I am also looking into E21 and E30 pumps. Anything I should know if I do get one? Any mods required?

Thanks for any help.

on the oil pump; chances are good that unless the engine has really high mileage,has been run with excessively dirty oil or little/no oil, the pump will still be within specs.

That being said, a 320 pump is identical to a 2002 pump except for the pickup portion. And a 2002 pickup bolts right to a 320 pump. I suspect the same is true for the M10 motor used in the E30.

Some years ago I found a closeout on 320 pumps ($75!), swapped pickups and in it went to my rebuilt engine. But I checked clearances on the original pump (204k miles) and it was still in specs!

cheers

thanks for that info. I am expanding my search. I think I found a thread on another forum where you got your pump in the closeout. Small world.

Apparently all the guts of the oil pump are still available-

as Mike says, you can 'tune it up' on your own with the

judicious application of refreshed parts.

I bought a couple of E30 pumps on closeout for exactly that reason...

I should add that 2002, 320i, and 318i pumps for the M10 are all available through Bavauto for around 350$. I just ordered one and won't believe it until I have it in my hands as I was previously told they were on indefinite back-order and I would be 8th on the list (I guess the shim is the part which is no longer available). Comparables for the same pump ranged from 500-650$ for a new pump so I would jump on it if I were you.

Now I just need someone to pipe up and say I am screwed without the shim. ;-) Still should have my original however.

great post on shims with diagrams FYI

So the prices have gone up at Bavauto.

The e21 320i (part #11 41 1 286 493) is 390

and

The 2002 (part # 11 41 1 269549K ) is 623.

So - I could order the cheaper pump, perform a pick-up transplant - and effectively save 200 bucks?

Metric Mechanic used to sleeve the wear area in the pressure relief valve in their HD pump.

I would get the e21 and use your old pickup. Bolt on deal acording to others.

Please provide more info on where you purchased an oil pump for $25.

Rockauto has the e21 pumps for $161, not sure if you're looking to spend that much but it's certainly better than buying an 02 pump.
