But you will need to get it very clean down in there no matter what you put in.
Surely brazing or something like that would be a more permanent repair ? It would definitely adhere to the cast iron, that's for sure.
I can get it tig/brazed but it will need engine removeing flipping upside down and crank removeing, I need to do what I can from above with the head removed, the hardblok will run and flow like wet concrete so will fill the voids easily, I honestly think silicone and a little plate above it would seal it tbh.
il hopefully have the head off tomorrow so will then be able to see what im dealing with and what access ive got, its a hateful engine the 3116 my first time working on it the injectors are in the head and theres like a cam in there, its rubbish and I hate it give me a 3306 anyday, when the engine fails I may retrofit a 3306 in the frame.
