i recently went 3-4 days without sleep,,lol,,,,wondering why No 1 cylinder wouldnt fire..To make a long story short I pulled the intake off and found the valley pan didnt seal by No 1 cylinder letting coolant flow into the intake valve everytime it opened...My question is do i get another valley pan gasket or order the 4 piece gasket set that includes the front and rear rubber gasket and 2 intake to head gaskets...

 

I think you're going to want to go with the valley pan. Keeps hot oil from splashing on the underside of the intake.
