51 psi at about 4000 rpm which according to what I've now read is about right, the crank (like the rest of the engine) is new so there's no wear groove.

If it has a 2 piece/1piece crank seal conversion they can be a pain to keep leak free as the alignment needs to be correct.
2 piece 1 piece conversions are best aligned without the crankshaft in the engine. There is a fixture available for this very job. check the block casting number at the rear of the block, and it should determine weather the engine is a 2 piece or single seal engine, Plumpcars may have hit the nail on the head.

Thanks for all the information, I have passed it on.
Check that he's running a pcv and engine breather. Mine had the same symptoms until I fitted a pcv valve. This takes away any crankcase pressure which can force oil through the seals, usually the rear seal.
I thought breathers on both valve gear covers would be enough for this but it wasn't on mine.
