73 2002tii head removed

Recommended Posts

Last week I introduced myself and my latest project car, a 73 2002tii that is stuck. I think the car might have been off the road for at least 20 years and maybe a burned out clutch is what took it off the road. After soaking the cylinders and trying to turn it for a few weeks I took the advice of those on the forum and pulled the head. I think the #1 cylinder is the problem, it was pretty rusted on the cylinder wall and that cylinder was full of the Marvel Mystery Oil while the MMO had drained past the rings on the other three cylinders. I cleaned it up some with emory cloth and I'm still soaking it some more. I cleaned the top of the pistons to read the markings, all read 88.97. The engine still won't turn with my breaker bar.  Can I get the oil pan off with the engine in the car to have a peek at the borrow end? Or am I wasting my time and I should just pull the motor?


Thanks, Don in Dallas

sadly, it'll be time ahead at this point to pull the whole block.  You may be able to beat #1 to bdc, but then it's not

going to want to come back up again.  And with that much rust, the rings will be stuck, almost for certain.

You will need to slightly lift the engine to drop the oil pan.  But, honestly? You need the block out for boring -- even if relatively slight -- so pull or drop the engine.  Lots of threads on pull versus drop engine: in my opinion, the engine droppers are shocked how easy it is and they also rebuild their front ends (most subframes wind up with a cracked left motor mount at some point).

Agree with TobyB and Conserv. 


Think about it this way: It depends what the goal is (as do so many things in life).


If the goal is simply to get the engine freed up enough to turn, and then eventually to run, you might get there through repeated soaking in MMO, incremental movement, maybe pulling the pan off and knocking the piston in our out, maybe honing and re-ringing, but look --> you're already getting dragged down the rabbit hole. You CAN hone and re-ring with the engine in the car, if the bores and the pistons and the ring lands are okay, but that's more than a big "if" -- it's perilously close to a fools "if."


So if the goal is instead to come out of it with a decent engine, you're probably better dropping the motor.


As someone who just dropped a subframe because of a cracked engine mount ear, it's really pretty easy. Letting the engine down on it ain't that much more work.

    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
