Yes I think you are correct - my thinking was that the smaller flange diameter may allow the bush to extend further into the timing cover, giving the ball a better chance to seat....and Mike (AMR) has confirmed that to ball is intended to seat against the bush. Thinks in this case the Mk3 bush thing is a blind alley.Starting from first principles I'm thinking of making an oil pump gasket with no holes - just to confirm there is no other (shudder) oil path.Otherwise may have to make up a rig like peterjoe did some years ago.Cheers
