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?

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

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.

1979 e21 318 (sold)

1975 Inka (sold)

1983 e21 320i (sold)

1974 Polaris (sold)

1975 M42 Swap (work in progress)

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
