Gasket application

Post by Bill Robinson » Fri May 23, 2025 5:03 pm

I know that some folks apply a gasket- (example: Crankcase pan lower cover gasket) by applying RTV sealant between the engine block and the gasket (apply to one side of the gasket), and then applying a real heavy grease to the cover rather that use RTV, then bolt the cover to the block. To be clear one side of the gasket gets RTV and the other side gets heavy grease. The goal is easy removal and re-use of the gasket. My question is- has anyone ever used the aviation product called EZ TURN? It's not effected by water, oil, gas and it is used on many aviation applications to this day.

My method is to use ultra black on both sides of the gasket then spread a thin layer of motor oil on the mating gasket surface where you want to cleanly remove. The silicone will seal & slick well, but peel clean without damaging the gasket. To reseal, add a small bead on top of the old, dried silicone & re oil the one surface as originally done. Use a drop on each bolt thread for a dry/drip-less cover. Would EZ turn work instead of oil or grease? Yes, but why use such an expensive product when plain oil does the job?

EZ Turn is the cure for petcocks and sediment bowl shut off.

I would not use it for gaskets, but it might work. Dunno.

Does this help?

Bill I have found that a big problem with these new gaskets is not leaking past them. It is leaking through them. Like a wick on kerosene lamp.
I coat them on all sides with gasket sealer. It soaks in and helps stop that. Then RTV, but that stops what you are trying to accomplish.
Just what I have found. Dan
