VALVE COVER GASKET – Silicone

for

CONTINENTAL Engines:

TSIO/GTSIO-520; IO/IOF-550; TSIO/TSIOF-550

(See complete engine list below)

   –   Our silicone rubber gaskets are made from aerospace mechanical

        grade AMS  silicone and designed to withstand temperatures up to

        400 degrees Fahrenheit.   

   –    Therefore, they will not break down and deform or crack up like

         cork or neoprene.   

   –    Our gaskets seal uneven and warped surfaces and 

         eliminate corrosion.

   –    Gaskets are 100% reusable.

INSTALLATION AND MAINTENANCE PROCEDURES:

THE GASKET SURFACES MUST BE CLEAN AND DRY.    

1.     Remove the valve cover and gasket in accordance with the Continental 

             procedure or in accordance with an acceptable procedure used by the 

             shop performing the installation.

2.     Clean the valve cover and the cylinder surfaces of all residual material.

3.     Install gaskets, DRY,

4.     Replace the valve cover and torque the cover bolts to 25 in-lbs.   

      “CAUTION”   –  DO NOT OVER TIGHTEN.    

       Over tightening makes the gasket bulge or squeeze out.

5.     Check the cover bolt torque after an engine run up to take off power or 

              first flight and re-torque the bolts to 20 in-lbs.

6.     Check the cover bolt torque annually, and re-torque to 20 in-lbs, if necessary.

      The gaskets are re-usable and the service life of the gasket is determined by its 

      physical condition on removal.    If the gasket is still pliable and without cracks, 

      tears, or deterioration, it may be re-used, otherwise discard.
