help wanted!

Good afternoon- had a strange thing happen and wondered if anyone out there has experienced/might now what is happening.

At the tail end of a rebuild - and nearing putting the engine back. Everything was going fine - all tests done etc - everything turning great etc.

I ordered a new flywheel and clutch assembly so dismounted the old flywheel (was torqued, but not all the way spec).

all I have done is mount the new flywheel, put the plugs in, put the valve covers on, and the engine mount bracket.

I tested turning the engine again and it is going, no binding etc, but it almost feels like there is air pressure building on the opening of the intake valves. Turning the engine is not as smooth like it was just prior to those items above done. Also, I hear some air coming out of the crankcase breather, sounds like a small leak or pressure release sound- is this all normal?

Is it possible that removing the flywheel and putting the new one on did something to the alignment inside the case??? Again, nothing is binding - just 25-30% harder to turn on the intakes and it feels like some pressure pushing against turning.

thanks everyone.
