My Cossie has burst 2 rads in 2 days and I've been told the cause is most likely head gasket. I have just gone from stage 1 to stage 3, but only running a peak of 20-21psi and holding at 17-18psi. I put a new head gasket in last Summer which was a standard one, but I was told it should be ok for that kind of boost. There are no other symptomns, no oil in water, no water in oil, no funny noises, in fact the car is running fine. So what do the experts think?

And if it is head gasket, is it right th next step is group A? If so, how much and where from?

Cheers!

dont take this as gospel but i have seen stage 3 requires a grp a gasket they are Ł60. i am having mine done saturday and a complete change new cambelt the lot is Ł425 plus vat

 

I think your expecting too much running peak 21 psi on a standard headgasket , fit a Grp A one.

Cheers Simon.

 

As said a standard 2wd gasket wont last for shit on a stage 3 set up mate, min recomended is group a or cometic.

 

dont bother with the grpa one - go for the cometic 3 layer one in the first place and then u can stop worrying abou tit blowing again
