I know I have many issues with my 55.1 235 engine as far as oil consumption and smoke. I found a mechanic sort of local who will look at it and i'm sure he is going to ask me questions about the motors behaviors. So i will tell him what I think I know, but i don't know why it runs great with some smoke and than after three months runs like poop and smokes like crazy. I change the #5 spark plug and it all gets better. So much oil on that plug, but compersion is close to other cylinders. I will ask him to do a leak down test as per advise from other bolters and if he dosen't do leak down test I will try to find another mechanic. Most of them say "put a 350 in it"
