Peter, could it be that the engine isn't mounted vertically, it leans quite alot...hence the sump prob...?

Nick,
It could be, the thing was intended to go in a front wheel drive car, mounted transversley....
But it doesn't look as if it is. But we are only talking a few mm out, so I'm not discounting anything!
Bottom line, the struts are excellent and positivly lock the bonnet in place, for me this is a big plus.
