i am in the process of taking apart my first sr20, and i am about to reinstall the timing chain except i ran into a small problem. i wanna make sure i get it right.
the crank sprocket has two marks on it and I'm not sure witch one is the correct mark. I've been searching all day and i haven't been able to find anything talking about two marks.

if anyone could help it would be awesome.

I never try to line anything up that way.

Get the engine tdc piston #1, then set the camshaft positions, 10 and 12 like all the diagrams and google searches should show. Something they do not show often but is very helpful is the lobes of both camshafts (for cylinder #1) will be pointing almost perfectly outwards, that is, along the horizontal plane of the deck. I say almost perfectly, because they are angled very very almost imperceptibly up.

And thats it. Ill repeat it a different way.

make sure piston #1 is TDC, then set the lobes of both camshafts facing outwards. Double check the dots on the camshaft sprockets are 10 and 12 o'clock and count the links between them.
