Advice needed - timing chain
Long story short, I'm replacing an engine on a 96 2500 silverado. going through gaskets and "easy" stuff now that I have the used replacement engine on the stand. while doing the timing chain and cover..when I put the new chain back on, the dots line up on the gears, but the teeth were ever so slightly off. I'm talking like 1/16" or so. the points of the teeth didn't quite line up. is this going to cause trouble? I haven't pulled the distributor at all and probably don't plan to. I did line up the dots when removing the old chain and gear...damn I had hell pulling the cam gear sprocket. my puller kept rotating the engine, so I had to keep taking it off and rotating til the dots lines up, then try again til I finally got it.

Re: Advice needed - timing chain
The dots on the timing gears are sometimes off just a tad.
So long as the dots line up through the centerline of the cam and crank you will be good. Note....and so many people make this mistake... When the dots are placed with cam gear dot at bottom and crank gear on the top, the engine is set to fire on cylinder #6. When the dots are placed with cam gear at 12 oclock and crank gear at 12 oclock, the engine is set to fire on cylinder #1. Your choice to remove the distributor and intake manifold, but the end gaskets especially at the rear are the usual upper area leak locations. Finally when you are installing the ignition leads, dont mix up cylinders 5 and 7....again a common mistake. Have fun...
