I would still pressure check the engine.   Recently I had a gasket set that came with crank seals.  One of the crank seals was wrong.  The ID of one of the seal was about .5mm larger than the crank journal. 

I noticed the problem when I installed the crank.  The crank seemed too rotate too freely.  It did not have the customary drag a new seal has.  Closer inspection revealed the seal was very close to but not touching the journal
