This K-Seal stuff seems like it might just do the job...........been looking around other forums for testimonies. This appears to be typical of the feedback:-
We had a head gasket go on a car (one of my family) rather than doing the job i put k-seal in, just to get me by untill the weather warmed up and i was gonna do the head gasket 18months later its still running fine - didnt get round to doing the h/g and no probs since can't say it'll be good for ever but the stuff does work 100% sure
I'll obviously introduce it with just the water that's in there for now. Just wondering what it will be like once I put the proper stuff in there. Talking of which, I have some G12 that I use for the MkIV. Is that OK on the MkIII or is it better to use G11?
