Michael Charalambous 12 Posted June 4, 2018 Hey boys, so last year my rear main seal leaked on my 351c. I replaced the seal and all sweet until now, it has started leaking again. It is a 2 part seal and many people have told me that they are a shit rear main and the better option would be to machine in a full piece rear main seal. Now I understand that the best person to talk to would be the engine machinist but I have one and would like some info before i start asking around so I have and idea what the go is. So the question I have is what is it called or do I ask for to disassemble the entire engine and machine without taking to much of the block away as I just want to clean it all up? The main bearings are 0.1 so has been machined before but dont want to go to much is there such a thing what I am saying? Also can all 351c blocks machine a full piece seal if not whats the next best thing? Finally I am in Sydney, NSW could anyone recommend a machine shop who knows 351c well? as I have never needed a machinist before. Sorry they are pretty silly questions but doing my reasearh and not coming up with much. Any help would be greatly appreciated cheers. Share this post Link to post Share on other sites
