Also noticed on the area of the timing cover that holds the felt seal .that the gap between the crank snout and cover isn't consistant, it's tight on one side and a good size gap on the other. is that acceptable? and will the felt seal make up for an imperfect gap.

Thanks for your help

The felt seal & the tool will not cure the play in the cam gear. The spec. is maximum .004 end play & .003" side play on the front cam bearing. Did they leave the front cam bearing out?


It sounds like some time spent with Plastigage now will save a lot of heartache later. The end play should be checked with feeler gages - .002 to .004". A new bearing job may initially feel tight enough to not allow the crank to be easily moved through the end play. .001 to .0015" is a good clearance on the mains & rods. They will quickly run in to a little more than that.

It might be wise to check that all of the oil holes have been opened in the bearings as well.
