so, since i have no idea when the last time the valve adjustment was checked or anyhting, i kinda want to pop the top on my car and have a look around, and generally give the valves a good pass over. from the pics iv seen it sems like a pretty easy job, since you can see the cam and the positions of the valves (unlike the V8s...kinda pain if you dont know valve order!) anyway, my question is how often should the valve cover gasket be changed. i know it was adjusted a year or so ago. and replaced not long before that..

cold motor

remove spark plugs

disconnect battery

hand crank motor by grabing tightened fan belt

it's easy to turn with the plugs out

position each lobe/rocker adjusted with the lobe pointing down

slightly past BDC (bottom dead center of each lobe)

adjust to 0.006" (0.006-0.008" Go-No-Go feeler)

and so on - read the manual - practice - reuse the gasket

no sealent needed - reuse many times untill brittle

special attention to the condition of the 2 thick aluminum

crush seals at the center oil feed pipe banjo screw

Must ne tight, but not so tight you snap off the banjo

screw head!

ok, so i adjusted and checked my valves yesterday. they didnt seem to have any probs but i need the practice so i adjusted em anyway.

the number 4 intake valve seemed very tight however. so after adjusting them to what i thought was a slight grab on the gauge, (.008) i now have a pretty loud valve clatter. should i just tighten them down more on the feeler?

    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
