So on top of the diff seal I went to check on her today and after being sat after my parents using the car for a month I went to start it. Was a bit missy for the first few seconds, but after a rev all was OK. Drove to end of road.. coolant level... Back down the road, checked coolant, and well, I've heard of mayo, but.. really, this was entirely brown sludge everywhere. Kinda hoping it's oil cooler rather than HG, it's had loads spent on it recently and I love having a manual MV6. But was wondering what it more usually is, or how often one of the HG go vs. oil cooler problems (which I know late vectra 2.6s suffered with too..) ?


Also, anyone close to bath who would be recommended to fit / fix?

Oil cooler.100%. 

[cem_devecioglu]

probably+likely oil cooler.. 

but a compression test may/may not tell more..

at worst you can call an oof mobile mechanic..

Oil in water = oil cooler gone

Water in oil = possible head gasket

Yours most likely oil cooler failed

Cooler. On V6, HG failure does not put oil in coolant.

Thanks all  , I'll get one ordered up. Is £150 on the bay a reasonable cost for one?

I had the same issue, was the oil cooler. I think I paid circa £150 through the dealer for the Vx replacement kit about 18 months ago so check them out too.

No imo. Last time I looked they cost that from VX. Might as well buy genuine in that case.

Mine was genuine from dealer with all the "o" rings, washers and the special sealer £170 inc vat. 
BTW when you do it don't forget to stand it over night without filling it with coolant to allow the sealer to set.

Rekon it'll be ok to my workshop 20 miles away. Temp is OK, think the coolant sensor is gummed up though. Will investigate the VX one! Going to be fun flushing it all!

Oh yes.  If you have a oil remover that sucks oil from the dipstick tube then I found that you can suck most of the contaminated coolant out of the engine by sliding the tube down the cavity that is at the front of the oil cooler when removed it goes down to the water pump and you can manage to ease it down to suck it all out.

About 2 weeks of twice a day flushing with a non-foaming bio washing powder works .... eventually ...

Apart from anything else, 2.6 and 3.2 don't suffer from head gasket failure - ever.
Flushing is a real pita.Ive done a few of these now,and am hoping to never have to do another one.
