Hi Paul,

If I remember correctly you have mayonnaise under the oil cap but not in the sump or in the expansion tank.

You say that the dipstick and oil filler cap smell like exhaust gas but again not in the expansion tank. In my experience, when the engine oil hasn't been changed for a very long time it has a smell which could be confused with exhaust gas.

I know that most people like to believe a man in overalls standing under official signage but I'm not entirely convinced that the evidence fits a diagnosis of head gasket failure. Maybe he's remembering the previous generation of the KV6 in the 800 series. The 75's version uses MLS gaskets and it would take serious abuse to destroy one of those.

Don't do anything drastic in the event of being quoted a large sum of money Paul. Say you'll consider your options and we can have a discussion about it here.

Stay in touch.

Simon
