^ Would this seal also cause an oil leak? Because there is a considerable 'mess' around the T-stat housing, between the heads and slightly below the exhaust. The bottom end uses gear oil? I've got an oil can on it and it is fed to to bottom end.
There is no oil injection system, I am premixing the oil. (as far as I know, no OI system.)
Can this be fixed with gasket paper or RTV? Or would it be advised to buy a gasket for it? This is a hard engine to find parts for .. it's a 524 or a 535... It originally came with a 440, apparently. this is not the original engine and the exhaust doesn't fit exactly right, it hits the brake. it's also hitting a part of the frame pretty good. I'm gonna have to dimple that, come to think of it.
