Im changing the oil filter housing gasket on my 455. I found a leak going down the oil filter so I took the housing off and am getting ready to change the gasket out. When I had the engine rebuilt the original gasket was metal but since I could not find a new metal one we replaced it with a fel-pro one. Since them I have found several of the metal ones,so I decided while I change my oil this time I would remove the housing and replace it with the correct gasket. My question is should I use any kind if sealer on one or both sides of the metal gasket or just use it dry.

 

Well I hope I side it correctly. We will see. I put the slightest film of Copper RTV on the housing side of the gasket and Left the other side alone.I torqued dont on it and filled it up with oil. I will start it today and see what happens.

 

The metal core gasket did not use sealer from the factory. You should be OK, but it wasn't necessary.
