Timing problem.

[next_is_10s]

So I am doing a timing job on my car.
Im ready to put the belt on but...I can not get the timing marks on the camshafts to line up. I turn the cam and they line up but as soon as I let go of the wrench it turns back to where it was. Somebody told me if this happens I have to back the crank some from tdc then turn eachcamshaft 6 full rotations then turn the crank and oil pump sproket 6 full rotations. Is this correct?
I have read all the articles and none of them explained what to do when the marks wont line up.


I need help asap.
Thanks

well ive never heard of the six time trick.... but the cam sprocket will never line up perfectly on ther own. you have to line it up with the wrench and hold it ther while you put the belt on. on my cars what i do is i line the first one up which is the the one on the left and i found that this one will stay perfectly straight up and down with the dowel pin. and the second one i rotate the mark on the pulley down past the the other mark on the left pulley about a tooth and then i hold it ther slip the belt on and when tat one cam gear goes to rock back it pulls the belt tight and it lines up the two marks perfectly every time.

what i did is line them up and take zip ties.zip tie the cam gears together it helps me when i do it myself

binder clips, padded vice grips... work to hold the belt to the cam gears and the belt when clamped to the cam gears holds them in place. this allows you to set it to the crank and set tension. Then remove the clamps and check your tension via the auto tensioner height inspection as stated in vfaq,

Yeppers, hold them with wrenches in the correct position, and then zip tie the belt to them both, the exhaust cam will want to pull away from the intake cam, but the intake cam is stopped against a lobe and won't move that direction. Then wrap it up as normal. Read the VFAQ for a timing belt install Timing Belt VFAQ (Timing Belt TSB - ENHANCED)

instead of a straight edge since i can't see it good from the angle I'm at on my 2g i use a small allen wrench and put it in the groove on the cam gear, then push it back to the head to see where the marks are actually lining up without guessing from the angle. I just started doing this 2 T-belts ago and it's been a great little trick to make it faster and make me more assured that everything is cool. Then you rotate the motor up to 6 times and make sure everything re-aligns. if your balance shafts are removed you only have to rotate it 2 times and make sure the cam gears line back up and check that the crank is as well.

Great info guys. Thanks
I have another question. How hard should my oil pump gear be to move? Should I be able to move it by hand?

yes..... you should be able to move it by hand, what do you use to kove it if you can't move it by hand/ how hard is it to move?

I agree with RB25, Mine spins easily when not connect to the timing belt. There is a weight in the pump (rear balance shaft) and it should naturally fall under gravity to the low position when the weight it on a side.... to give you an idea of "how" easily it should be able to move.
