You just had to ask

I use this Permatex Super 300......seems to work great for me

Oh...yes.....it is not so easy to remove my Permatex Super 300 gaskets (I use single edge razer blade) but having said that....it is hard to imagine a gasket that is not sticking upon removal also sticking enough to do its job......if that makes any sense

I have NO leaks on ZR1 (LT5s), Corvette (L98s), Toyota Trucks, John Deer Tractors......

I use Permatex Super 300 on gaskets such as oil pan, Injector Housing Gasket to Head, and water pump gasket (including thermostat gaskets or in our case thermostat mating surfaces) where oil or coolant is involved. I also use a bit of this Permatex on coolant pipes by lightly coating the inside of the hoses before I slip them on the coolant pipes. I also use Permatex Super 300 on oil pan drain plug metal gaskets and oil pan drain plug threads. I do not use Permatex on Head Gaskets, Plenum Gaskets, or Cam Covers.

On gaskets, I coat each side of the gasket lightly (very lightly) with Permatex Super 300 and then let it sit until the Permatex gets tacky such that the gasket will stick in place (helps keep gaskets in place while placing water pump or oil pan for example).



Permatex Super 300 is a non-hardening sealant designed to resist heat transfer fluids such as oil or antifreeze. Temperature range -65°F to 400°F (-54°C to 204°C); resists antifreeze, aviation fuels, aggressive detergent bearing oils and lubricants - See more at: http://www.permatex.com/products-2/p....cpTjeJ8R.dpuf

There....admitted it....let the debate begin......
This is one of those personal preference things where there are many opinions.
