hi guys got a new motor all done right by book by engine builder. last thing to do was put water in so i did and water started leaking out the extractor side quite a lot.. thinking that a welsh plug did not seal so took all of.. pumped up cooling system and water pouring out from between the head and block.. for the life of me cant see how this could happen.. thinking the gasket is 92 thou and it has failed so how??
any one have an idea
