I've not long acquired a 2.5v6 elite with only 81k that i thought would give me a simple life. ('only just serviced mate') However, it's got teething troubles and if there are any birmingham/midlands based mechanics out there that can help then please get in contact!.
i'm not too bad with a haynes, but my OH wants bathroom lights and other priorities which limits time under the bonnet! as i'm only a newbie on here i've read lots of threads and hope i'm not repeating too much.
Despite having omegas for years my first oily coolant prob has arisen! It seems from all the info here that there is a problem with the oil cooler. And agreeing with previous comments, every garage i've rang about the problem says straight away it's head gasket! grrr! they don't like it when i say head gasket is a rare failure on the v6!

symptoms are brown oily stuff in the header tank. a stiff cap, fluid leaking after driving through traffic the other day (noticeable in a shiny new multistorey!) and now an empty gungy header tank.
help? advice? shall i do a coolant flush for now unti a proper remedy can be sought?
one dealer quoted nearly £300 for a oil cooler, plus labour, and advised me not to drive as the gunge will be clogging everything up!
ps there's even that dreaded 'burning oil smell' but no evidence of rocker gasket leakage... yet :-|
