Just one thing : if you want to test the air seal, just take the air compression system (nozzle, cylinder, cylinder head and piston all assembled), put pressure on the nozzle (don't make the cylinder head go back into cylinder) and push on the piston, there should be some compression but you should be able to push completely (don't force it though).
