Belt Noise?

08-08-2017, 01:33 PM

I just put my motor back together and it seems I'm having some really loud noise come from either the timing belt or alt/water pump belt. Definitely not internal noises. I have Russ's adjustable cam gear on this and was wondering if that could be part of the issue (they are torqued down to spec). Link to video below for thoughts please. Symptoms of a belt too tight?

Looks like its the timing belt, found this link below. Will try alternator belt first, but…damn time to dig back in.

Do I detect a hint of wobble in that timing belt? Looks like it may need a pulley adjustment. I need that adjustable POV BTW!

Hmmm…I do see a little bit of wobble in the timing belt. Ideas on what would cause that? Maybe crank pulley not completely pushed all the way back? Cam gears?
