i have an 87 e30 that i would like to adjust the valves on. however, i can't figure out how to check to make sure that cylinder number 1 is at TDC without having access to the camshaft timing sprocket (which is located behind the timing belt cover). i know that the O/T mark on the crankshaft pulley timing wheel needs to be aligned at the same time to ensure that cylinder number 6 isn't at TDC and not cylinder number 1.

could someone who is showing up to the tech session at Funktion show me how to do this or some other way to check that cylinder 1 is at TDC.

thanks,
jim
