i took apart my port engine due to some steam and about 1qt/hr of oil loss. I have a new heat exchanger, fuel lines, injectors,thermostat, valve covers, and gaskets. I cleaned the core of the aftercooler and I’m unsure if I should use a thin film of white lithium grease on the new paper gaskets. The engine is the gm peninsular 6.5 turbo diesel. Any thoughts would be greatly appreciated.
