I am using a Roll Master Double roller timing chain in my new motor.  When I installed it and turned the engine over by hand, I noticed the chain made a tiny clicking noise when the chain and gear meshed.  It went away after a while.  When I tighten down he crankshaft balancer, the tiny noise returned.  The chain is tight and the cam degreed perfectly. The front cover is on the engine now.  Should I worry about this?
