Re: {FORGED?} Re: Finding TDC with a dowel

A: Actually, timing marks can lie! But only in certain circumstances. If you 
have a harmonic balancer with a loose/oily rubber between the inner and 
outer rings, and the fan belts drive off the outer ring, there is a high 
liklihood of the ring slipping (usually a short time before it fails 
altogether!) On balancers that are solid and not 1 piece, the woodruff key 
that is supposed to keep them in place can be sheared through a number of 
unfortunate circumstances (loose crank bolt and the motor or belt driven 
accessories coming to a sudden halt is one way!)

Timeing marks don't lie unless the engine has a sloppy timeing chain and has 
jumped time. Bump it back clockwise a tooth or two and see if that will make 
the engine run. I can only sense your frustration and hope you find the 
problem.
