there are two marks on the main crank pulley. spin the alternator nut with a large crescent wrench until you get the first mark to line up with the pin on the front cover.

then blam you are at 5 degrees btdc

Are you asking how to set the timing to -5 degrees, or when to tell that your engine is at TDC position?

Take the cover off of the CAS and hold the wheel with your thumb while you stab it. It may move a bit, just don't let it jump a tooth.
