Finding Dead Center
I have a 98 323is. They make a tool for top dead center that goes thru the block and into the fly wheel. That hole in the flywheel insures the correct timing for top dead center compression stroke. what I am having trouble with is there are two (2) holes, one on each opposite side of the fly wheel. So does this mean as long as one of the two holes are lined up that it will be in time. If not how do i know which hole is the right hole.
