timing belt rubbing.

Changed the tblet among other things, finally got it all running right, but the timing belt sounds like its rubbing or somethin at one point in it's rotation.  What causes this?

Over tensioned? or is it the fact I only put 2 of the 367 timing belt cover bolts back in because they are all a total bitch

pry a litle loose and is rubbing on the front half of the lower cover super common. i would say try tensioning it again and see what happens

Happened to me my first time... I didn't have enough tension.

Whats the best. Way, I just trieod pushing up on the tensioner lever while my buddy tighteninged the bolt.  Heard you can also rotate the cam to tighten

Hope the mechanical timing is still being maintained.  ;D

Did you make sure both the flat washer looking belt guided are there.? Look at the crankshaft TB pulley are in the illustration below.



Yes I know that is a D16 zc belt diagram. The crank end of the TB setup is the same.

Ive had this happen a few times with some bets b4, its normally because the plastic gets all bent out of shape for all the heat cycles from over the years.

Word and I have seen melted ones too when people really overheat the motors.

To make sure the belt has enough deflection i usually put everything back together except the timing covers check mechanical timing via two turns of the crank. Then i turn the motor on and verify no wierd noises. Once all noises are comfirmed non-existant i usually poke around near the belt with my fingers while the engine is still on. I like to check the area right on the ribbed side of the belt where the belt  starts to wrap around the cam gear

The inside plastic between block & belt was wore mostly from extra-long cam gear bolts, but it still warped out a bit.

The proper way to tension the belt is to do the method above. Just make sure you have a relatively new spring in there, and smooth surfaces in, on & around the tensioner pulley.
