I am looking at an 1175 case tractor. I noticed that there is a lot pressure coming from the breather tube.

The breather tube is the tube that sets on top of the valve covers.

There shouldn’t be pressure on this tube but it feels like a compressor pumping air.

Normally my first thoughts are that a head gasket is blown or there is blow-by from worn compression rings.

But the engine runs fine, does not smoke and there is NO water in the engine oil or extra pressure on the radiator.

Normally an engine with this much pressure would smoke badly or have water in the oil.

Instead it starts and runs fine.

Any ideas?

The engine is a 451 turbo charged engine.

Forgot to add is there a chance the extra pressure is coming from the blower

If the sleeves are not badly worn, you could replace the rings on the pistons. I replaced the rings on my 1150 dozer with very good results. Currently, your oil control rings are working well, but the compression rings are worn out.
