so if the problem isn't the cooler, why not reverse the bypass? If the leak is in the no 1 input module its going to keep leaking regardless isn't it? Why risk overheating the engine inputs as well?
Not a 92 driver so just keen to understand.
I think the purpose of the bypass is to save as much oil as possible in the event of a leak. Hot oil is better than no oil. I can’t remember what the capacity of the cooler is, I’m on leave but it takes a fair amount.
