 Before the doom and gloom congratulations on owning a JH, the're a great car as demonstrated by the taking of a class this year in the HSCC Championship http://www.hscc.org.uk/ and me getting a class win last year and a 2nd this year in the HSA Championship http://www.hillclimbandsprint.co.uk/

Oil in the water is never good news and certainly hints at a head gasket problem. Not a very difficult or necessarily expensive job - it's the '....while I'm at it I might as well do this, etc' that bumps the job up. Certainly needs sorting asap or it could get pricey.

Apart from warped heads and dodgy liners I've had problems with head gaskets with (wider) rubber sealing rings around the head oil feed hole as opposed to types with a (narrower) copper ring. The amount of metal around the oil feed hole in the top of the block is not great and if the edges have been knocked of by corrosion and the gasket locating dowels are not working as they should then the gasket can be out enough to cause sealing problems.
