Rb20 Timing Alignment Help

[GTAHH]

G'day, one question and yes i've ran a search.

At the moment i'm a little confused so I apologise if this is a newb question

I have changed the water pump, marked the timing belt, and put it back on correctly. But the thing is, when I turn the engine over manually (tensioning it) the marks are moving and not lining up with the cam gears? I.e One full rev the marks would have moved say 2-3 teeth along the cam gears, and it is like this on both the intake and exhaust. Is this normal? I can't remember if it is but I would think it's not.

Cheers!

yes im guessing this is normal.. i had the same dillema with my rb25, i freaked out when i first saw it, but if you wind in over backwards they re align... so the teeth havnt moved.... i hope :

Yeah mate, i've done a few before but never actually looked. I pressume it's becuase of the different number of teeth so it should be sweet

You will probably find that the number of teeth on the belt is not an even multiple of the teeth on the cam wheels.

All that is important is that the marks on the cam wheels and the mark on the crank pulley line up at TDC #1.

The marks on the belt are there to help you set it up easy, once you turn the donk they wont mate again. As long as the cam gear marks mate with the marks on the backing plate when the crank pulley is on TDC you got it right .
