This is an interesting thread, although old Kaiser seems to take umbrage at other peoples advice a bit toooo quickly. Clearly with liners like the K4 engine has, there is the possibility that the bottom ends of the liners can leak as well as the well known top end (aka HGF), they are only sealed with a small bead of Hylomar after all. I would think the sealant mentioned by Kaiser would be able to close off leakage at the bottom of the cylinder liners as these are only under the cooling jacket pressure not the combustion chamber. There used to be a product called Bars Leaks which was actually recommended by Jaguar
So lets see how Kaiser gets on. He seems to be a big softy for the Rovers despite his comments that I have read over the past few years on the 4 and 6 cylinder engines. I have to confess to having similar feelings of exasperation with MG Rover and their failure to deal with obvious faults promptly
