oil & coolant!

Hello folks - just found this excellent site and have joined right away. Have an F reg 760GLE automatic Estate that has done 230,000 absolutely trouble free miles but...................! I now find that I have some very unpleasant thick buttery goo in the coolant header tank. It is definitely an oil emulsion but I'm not using any engine oil - the goo has a smell that reminds me of automatic transmission oil. There's no sign of anything untoward on the gearbox dipstick. Is major trouble about to appear?? All comments/advice gratefully received. Big question - what would you all recommend as a replacement for the 760 if the unthinkable happens?? George

Agree with Madder93; although it was a few years ago that I had to replace my rad due to this problem. Would recommend that you change auto fluid, even though it may look ok, as any water/coolant in it will not do the auto box any good. You will obviously need to flush cooling system thoroughly to get any contamination (emulsion etc.) out.

Thanks guys - new radiator it is then! The 760 really has been a fantastic car - why did they ever stop making them?? George

Hi, Welcome to the forums and enjoy your stay - seems like yoiu'll likely have fun here.. :) If considering a replacement for the 760 then as suggested - ANOTHER... :D OR you could step up to the 960 - you can pick these up fairly cheaply these days. Or you can have a crack at the 740 or 940. See how the other half live.. Again these can be picked up reasonably cheaply too... Des. . . ;)
