Help - oil pressure / flow on engine first start.

[David Cochrane]

The cause of the wrongly-placed oil pump gasket could well be because of the highly misleading illustration in Austin's Lists of Spare Parts, which show the gasket between the cover and the body. These illustrations are not like a modern exploded diagram, but it's all too easy to assume that illustration shows how it should be assembled, especially if you're not familiar with how the engine should go together.
