OIL SUMP or OIL PAN GASKET  – SILICONE 

for

CONTINENTAL ENGINES – IO-346-A; IO-346-B

• 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

                  eliminates 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.” *

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.

  *   Over tightening causes the gasket to bulge of squeeze out.   

       If that happens then back off on the torque.

TO REUSE GASKETS:

Wash gaskets briefly in hot soapy water.

Rinse well and dry all surfaces.

Re-install using the above installation instructions.
