M10 rear main seal - Same for E10-E30?


Recommended Posts

well my engine was rebuilt by the previous owner, and apparently he botched the install of the rear-main, or reused an old worn out seal or something equally as ridiculous.

i started removing the auto tonight but it got dark, i'll continue tomorrow.

so will an E30/E21, manual, 4spd auto etc rear main seal fit a 2.0L M10 with a 3spd?

i'm asking because i'd like to pick one up locally, and people tend to look at me stupid and ask what 3-series a 2002 is... an E30 rear-main should be much easier to obtain.

i'm assuming it's rear main leak because (engine) oil is being flung off the flex-plate through the timing hole, and the behind the inspection cover the plate has a nice coating of oil. i'm guessing it's pretty conventional inside a 3spd behind an M10? any advice or tips you could provide would be excellent. TIA

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
