I want to ask questions about timing that will give me the proper understanding of the timing, not just reading the idiot marks. My first question however is about one of the idiot marks. LOL.
Diamond on the cover above the oil pump sprocket and the notch on the sprocket. This is correct for TDC?
Second question, if I remove the timing cover with the marks on bottom how do I know where TDC is without the cover marks? I have the number one piston up (and number 4 of course) at the top so I'd like to know if that is all I need to be where I need to be or if I rotated it again the marks on the harmonic balancer would change position when the #1 piston comes to TDC again? (like a 2:1 ratio)
I have the head ready to go back on the engine so I can set the head anywhere I want before I put it on. What is the way to make absolutely sure it is at TDC just like the oil pump and harmonic balancer?
