sorry for the basic nature of the question but what are the steps in changing the cap and the rotor on the cars? is it a straight bolt on replacement or do i have to adjust something? also would like to get the torque spex...

thx a lot. am forced to work on the car myself coz the bmw dealers here in my country are idiots and I cannot find independent specialists - M owners in the western hemisphere, please consider yourself very very lucky..

regards and thanks in advance

Straight bolt on procedure. You may have a hard time geting the cap off because the upper coolant hose may be in the way of your wrench. I used a socket on the lower screw and an open wrench on the upper one. The rotor requires the use of an allen wrench. Can't remember sizes or torque specs, sorry. Hard to use a torque wrench on those little allen head bolts so I made them tight w/o over tightening. Did that make sense? Hope so. The cap is numbered so you shouldn't mess up which spark plug wire goes where, just match the numbers.

previous post say's it all (no need to over tighten,they are small 5 and 6mm screws just hand tight you can put a small amount of blue Loctite on the allen for the rotor if you're worried (note i said blue and blue only!))

and there are no adjustments to make as the timing is all controlled by the Motronic's.

while your in there pull the plug wire loom apart(small screws in underside) and look for signs of arcing or rub thru on the plug wires.(this applies if your car has the stock wires still) i have Nology wires on mine for this reason
