right so my rocker cover is milky as a milkybar so obviously head gaskets gone, Ive tested the thermostat and its jammed shut so thats probbably what made the hg go.
Does anyone have any ideas/tips on hoe to clean away all the milky crap? ive heared of some people putting desiel in and running on that but I thought it best to check with mini people as im a bit weary of pouring desiel into it.
Doesn't put foot in mouth enough!

That sounds like a sure fire way to break something!
I would do a comp test and if it looks like the head gasket then replace it, take off the rocker cover and clean it and the rocket assembly,and then get some cheap 20w50, hellfrauds or similar and run that for a few miles, see how it looks if its still a bit mayo-ey then flush it all through and refill, that should get rid of it I would imagine.

Take the rocker cover off and use a decent degreaser to clean it. Won't take long and will be an easy job.
Just as a thought if the engine is running fine, do you do lots of short journeys? This is an easy way to get a build up of condensation which can lead to the milkiness.

Mine is purple, but I have been told that's normal

As above, is the car using any water? Do you do lots of short journeys?
Do a compression test before assuming it's the head gasket!

thanks I thought the desiel option was a bit mad
yeah I do a lot of short journeys but I was getting steam out of the back so hg almost definately need replacing

Steam could be condensation!
Minis usually blow head gaskets between pistons rather than between oil and water ways!

Do a compression test and work forward from there. Does sound like HG but it's not always the case.

okay thanks for the help guys :)
I shall do a compression test on it when I get some free time

as above it may not be the gasket,
some oils are really prone to "mayonnaiseing" just from the water vapor in the air. when I was using the green classic oil i had really bad issues with this, but swapped to millers oils and it cleared up.
also I have actually done the Diesel flush thing on an engine, not somthing I would recomend anyone to do, but it did work for me.... it was a gunked up old FSO pickup engine that had probably never had an oil change, dumped the oil, stuck a gallon of diesel in there and fired it up and left it to tick over for 15-20 mins, then did an oil and filter change on it, engine ran fine after. I did however have a spare engine so wouldnt have been fussed if the diesel killed it.

always start with a compression test and then work from there.. HG failure will result in lower compression readings.. so do check on that first..

Likewise. However, I used Kerosene (only slightly different than Diesel really). As above, you do NOT drive the car/truck with Diesel in the crankcase, you let it idle for several minutes (at temperature) and NO LOAD. You immediately change the oil and filter and typically run that oil for only a short time before changing it again.
Though this may sound horrible to some (particularly younger) readers, it is an old-school technique. It was used more in the days when oils commonly formed sludge in the crankcase. You don't hear of people using it these days as engine oils are much higher quality now.
There are also commercial engine flush chemicals you can add to oil prior to doing an oil change. Most pundits argue against the product and practices today because anything you dislodge that was deposited by modern oil is likely to be hard and may find its way to someplace other than the filter... someplace like small crossdrillings in the engine and bearing shells.
