M44 Swap Which Oil Pan And Pump?

post-32364-0-69717200-1370130378_thumb.jIsn't the M42/44 pump wrapped around the nose of the crank, in a fashion unknown previously (or hence) to BMW?

 

One that precludes bolts falling off, sprockets coming loose,  chains failing, or other potentially devastating failures.

 

So I think you just make sure the pans have the same passage arrangement (the pickup is in the pan) and bolt them together.

 

One note- getting the M42 to prime itself is not trivial- make SURE you get oil pressure before you let the thing fire...

oh God haha so any idea what i do about the pickup? I have the e30 oil pan and pickup and the e36 oil pan and pick up can i make something that works out of the two? can i weld the top half of the e36 pickup to the bottom of the e30? also i need the m42 lower timing cover?! where do i get one of those doubt people will be parting those out :/

The way in which the pickup system works varies drastically between the two engines. I don't see any way around installing the lower (inner) timing cover (which includes the oil pump) from the M42 onto the M44 in order to use the front sump M42 oil pan. It's been a few years since I did it but I don't recall any decent workaround and I'm pretty creative.

No, not if you're going used. The oil pump is part of the cover assembly. The difference is in the way the pickup attaches. The one possible way you might make things work without the cover is with some really creative welding / fabrication. Go ahead and source the used E30 sump and remove the E36/M44 sump. Then you'll see exactly what I'm trying to explain. HTH

Doinking around in Penskeparts, it looks like it all changes in 9/95... oil pan, pickup, etc. 

That would coincide with the M44.  And all of the E36 stuff looks rear- sump, where the

2002 needs a front sump...

 

But thinking back to playing around with E30 M10 pans, THEY don't exactly fit into the

2002, either... but they ARE front sump.

 

In my neck of the woods, I'd hit the pik- n- pull with my 10mm socket, drill, and an assortment of extensions.

Your engine appears to be an M42, not an M44. If you look at the diagram Toby posted earlier in your thread you can see the type of pickup I have been warning you about, which wraps up and over and bolts to the back of the timing cover, rather than pulling oil up through the port in the bottom of the cover. Maybe it's different than the '96 M44 I set up for a swap. You can bolt the front sump pan right onto that engine.

That DOES look just like the bottom of the M42... but those little rockers scream M44.

 

(btw, they actually reduce mass, by letting you put the hydraulic lifter in the block, and you also get a roller, not a slider, cam.  Said the cam shop.

Doesn't seem like progress, but apparently, it was.  Who knew?  Not me.)

    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
