Oil in expansion tank?

Do you mean the gearbox oil cooler has gone, rather than the engine oil cooler?

Jim,
Oil in the water is never good and depending which system you have, can be very bad news. take it to a specialist unless you know a competent mechanic. Trust me, you won't regret it
Cheers now
