I am going to try it. Can anyone recommend a brand . The Disco I am interested in has supposedly a cracked block. More likely it is the head gasket. So before doing a big job I want to try the mechanic in a can....looking for ideas and previous experience.

 

I have had some degree of success with " K-Seal" ........, it cured my wifes leaking intake gasket for 2 years before we eventually did the top end gaskets, also had some luck on my '95 D1...if you're lucky it can buy you some time, maybe slow down the coolant loss......just dont expect a permanent cure...lol
