How much air / pressure are you pumping in ? It should only be about 8psi , too much pressure and any seal will leak .

6 psi

Hallelujah!!! She is air tight

Replaced the seal and the hallite washer bit, found I tiny leak on the inlet manifold sealed her all up and happy flippin days, the dial ain't moving at all. Only took three days!!!! I have never bothered leak testing before and have learnt the hard way with seizes and holed Pistons. So, not saying it will never happen again but at least I have learnt a little more about engine building and that can only be a good thing. Thanks again for all the help on here

Make sure you smear a tad of grease round inside of seal, so it slips over crankshaft easily
they can get folded if not
