Following similar issues (previous owner had) with my current TS magna V6, and my discussions with Magna wreck on the goldcoast QLD, they indicated to me that the TS magna v6's had an issue with the relay for the thermofan/s, which caused overheating, and which also caused weakening or blowing of the headgasket.




Ok, lets look at it from both a fitters point of view, and a motor mechanics point of view:

A headgasket which is sandwiched between 2 hard metal (or alloy) surfaces just dont "BLOW" for no reason. There has to be SOME sort of weakness, scratching on the head / block etc etc which will cause leakage of water or air to cut or "blow" through the gasket.



Common headgasket blows are caused from overheating and faulty valve opperation, and less likely are caused from damaged head / block surfaces unless they have been removed before and replaced without machining, or not tensioned or re-tensioned correctly.

I personally would check the following:
1: thermofan opperations
2: Compression, Then the following,
3: head surface to ensure it is straight,
and
4: head and block surface,

9 times out of 10 the reason heads fail is lack of coolant which eats away the alloy and head gasket ..... and as for undoing the bolts you can un do the bolts any way you want its putting it back on is when you need to start from the center bolts and work your way out
