Cylinder Head Reinstall Questions


Recommended Posts

Hi Everyone,


It's been quite a while since I've posted here.  My '02 has been out of service since December of 2011.   I had a problem with two striped spark plug holes, and nearly  two years later and a lot of money spent on parts I need to get this car reassembled so I can use my garage again.  


I ended up having my original head completely redone after the machine shop found it to be cracked and warped.  It looks great, but that was a year ago.  I've delayed reassembly due to several issues, my lack of confidence in correctly reassembling it being the primary reason.  I want to know how you get the pistons on the block back to TDC on the first cylinder as well as making sure the head is also similarly calibrated.  During the tear down the timing chain slipped, and I am not sure the #1 piston was at TDC when I took everything apart.   Can anyone who has done this before offer some pointers?  Anything else I should do for an engine that has been sitting for almost two year without the head???   I would really appreciate it! 


Also, when I parked it, there was gas in the tank and lines.  No stabilizer added.  Any advice on how to deal with this issue?  I was thinking of replacing the fuel line, as I have no idea how old it really is.  How about the gas in the tank?  there was less than 1/8th when I parked her...


I appreciate any advice, you can spare!

The crank tdc isn't too hard- bring #1 to the top, and rock it back and forth.  There is a 'dwell' point where the piston

won't perceptably move.  Rock it back and forth until you're pretty sure you know how wide that point is-

then split the difference.  If you can make marks on the front pulley, so much the better- one for each end,

then split it, and MAYBE you'll find a tdc mark on the crank pulley.  Maybe.


The head's easier- make sure the line on the flange on the front of the cam

is in the middle of the 'casting flat' on the head itself.  Again, there's a little leeway for interpretation, but get it as centered as you can.


Then install the head, and put the chain and upper sprocket on.  You SHOULD be able to put the bolts through easily-

but it's not uncommon to have to wiggle just a little bit to get it to line up.  If it's way off, then it's time to double- check everything.


Not too hard,

    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
