Engine must be at TDC as long as the timing mark on crank and plate fits in cam right?

[mawrick]

When I started the timing chain job I was under impression that as long as timing mark on the crank, and the plate for the cams fits the engine is in TDC, after I took of the chains I noticed the arrow on the intermediate gear was off by 180 degree, but also read somewhere that this only lines up every 4 rotations.

I hope I'v understood correct that the engine uses 2 rotation going from TDC and back to TDC ? (I just put the oil pump and HPFP in on the marks when I put on the new chains.


Just wanted to check too be 100% sure I couldn't have fu** up anything when I put it on what I belive to be TDC......


thanks again
