Timing Chain Cover crankshaft opening is the wrong size

fulltank said
This is the backside of the harmonic balancer, is the cap ring attached to it going to interfere with
the crankshaft seal for the new timing chain cover, just trying to cover all the steps.

No, you're fine. Put a new seal in the timing cover and test fit the balancer if you'd like. Should fit fine.
