In fact, let's examine the worst case scenario: all four valves are so tight, you don't have
any valve clearance for
any valve at
either TDC position. You don't need to experiment to find TDC on the compression stroke.
If
both timing marks are aligned in the cam inspection ports, you are
definitely located at TDC on the compression stroke.
