Google "E30 timing marks"

The pictures will tell you where the marks are that need to be aligned so that the timing is correct.

Take your spark plugs out so that if you feel any resistance when rotating the crank you will know that a piston is touching a valve and that you have to rotate the camshaft before rotating the crank any further.

BR is right... one thought I had too is that if you haven't moved anything, you *could* try to put the belt back on. As long as you don't move the crank or camshaft pulleys, in theory, it would be just as you took it off. Then you would rotate until the timing marks align.

But I could be completely wrong.

Make you sure you do a couple of full revolutions by hand before starting the engine...

Wow, bit risky folks, just slipped er back on without knowing if it moved off, almost as silly as removing it without knowing what to do after that to start with.

If all he did was take the belt off, he likely didn't move the crank or cam pulleys - they aren't that loose. I've done my timing belt 3 times now, and neither one has moved while taking the belt off and when I rotated the engine, timing was bang on.

Yes but depending on where the cam was it could spring if its holding valves open
