crank scraper question

Locomotion said
Just gotta give more attention to sealing the front & rear pan seals because you lose some "squish" with the scraper installed on the rails.

Old topic, but I tried to find info for sealing tricks. I installed the ishihara crankscaper with permatex supra black silicone and put the oem style cork gaskets + rubber back and front seals. Had it installed many days before I put oils in it and primed the engine oil. Front seal leaks a lot and now i have to take it apart... I put silicone on pan and timing cover surfaces and it still leaked. Every surface was cleaned very well before silicon and installation.

Opinions?
1. Do I have to put a lot more silicone between the sealing surfaces
2. Or, do i remove the rubber seals and install the pan only with a lot of silicon?
