Block Off Plate Installation Instructions:

1.     Thoroughly clean the engine block mounting surface and the block off plate so that both are free from grease, debris or other contaminates.

2.     Use BrakLeen (Red Can) or equivalent as final cleaning step to prepare both surfaces.

3.     Apply a thin layer of FORD Motorcraft Ultra-Gray Silicone Sealant or Hi-Temp Silicone Sealant (EGR Block off only) or equivalent to the back of the block off plate in contact with the sealing surface of the engine block.

4.     If the bolt threads protrude into the crank case (i.e. are not blind tapped holes) apply a small amount of silicone sealant to the bolt threads.

5.     Install block off plate to the engine and torque bolts per engine manufacture’s recommendations.

(NOTE: Gaskets are not provided with the kit nor are they recommended. Two bolt mounting systems typically associated with mechanical fuel pumps, EGR valves and Intake manifold breather plates were not optimally located to provide even gasket compression around the sealing surface which is why they invariably leak. If you choose to use a gasket to seal a block off plate, apply a thin layer of silicone to both sides of the gasket.
