Re: 1929 Johnson V-45 Head Gasket Torque Recommendations

[PM T2]

George makes a good point about re-torquing. When I was building car engines, the standard practice was to re-torque cylinder heads after the initial run was completed on a fresh engine, and you did it HOT. I was taught to break the bolts loose one at a time, and re-torque to specified value immediately before moving onto the next bolt i the sequence. The end result was that I built many street performance engines and never had a single cylinder head gasket failure in any of them. I’ve never rebuild an antique outboard that had cylinder heads on it (although I’m in the process of working on a Kobunn), but I have done several cwassic OMC’s, and I always retorqued those heads too, I guess it just became habit.
