HI

I have just installed a new timing belt lined up all the timing marks made sure all the single timing marks lined up with the belt timing marks.

Put the last orange roller back on checked the marks again pulled the pin out of the tensioner all looked fine.

Turned engine over by hand slowly always a bit nervous at this time LOL
all turns over fine with 4 compression strokes.

But my question is if you keep turning the engine over should'nt the belt timing marks eventually line up with the cam single timing marks like when the belt was first put on. Because now all the engine timing marks line up at TDC but not with the belt anymore no matter how many revolutions.

No, I don't think that's the case.
As long as the timing marks line up correctly after each second revolution then you should be fine. I wouldn't expect the belt marks to like up with the camshaft marks again until you had rotated the engine many, many times.

Edit: If you are SURE that the engine is rotating (clockwise)without obstruction and the timing marks are lining up correctly then you should be safe to start the engine to test. If even one pulley is a tooth out, it will run like a bag of spanners.

I assume you mean clockwise as standing in front of the engine.
I will put up an image of the marks after 5 or 6 revolutions.

Yes, looking at the engine from the front.

These are the timing marks after several turns but as I say the belt marks no longer line up.

the marks on the belt are there to help with fitment once the the belt is fitted and the engine has been turned over twice by hand if all the marks on the pulleys line up then you are all good, you would have to turn the engine over dozens of times before the lines on the belt were to be inline with the pulleys again.
