I just swapped 318's in a truck and the only difference was that the new motor had the 90 degree oil adapter on it and wouldn't clear the headers so I swapped them out and I didn't see a gasket or rtv so I just bolted it on and it obviously doesn't seal at all am I supposed to put a gasket on this or RTV? Since this is the oil were talking about I don't want to take any chances.
Thanks, Kevin
