So I have been dealing with a 6V53T that was overheating. The boat is stored at Billings in the winter and comes here for summer. Greg has many more years experience than me and definitely knows his way around Detroit’s better than I. During the whole fault tracing process our “mental flow charts” were basically parallel. He also managed to shave our 3 week wait for gaskets down to 2. Even now when in the “disassembly and investigate” process we are still pretty parallel on our thoughts and he remains a phone call or email away.
