Mostly, you are posting on an oldish thread... but:
Also on the crank, how do I know I am TDC before intake or exhaust? I am afraid it will be 180 out and I will have to take back apart.
The crankshaft & pistons don't know whether they are compressing or exhausting. They may be both.. Any way, the crankshaft needs only to have the #1 piston at TDC, in either case. However, the cam & timing needs to know it is the end of compression or exhaust, so they have to be set individually. The cam with the triangle in place will put the #1 valves with the intake having closed, and the exhaust ready to open next, and the pump drive will put the sensor at #1 ... So the crank does not care! Whoopeee!!!
