Why take chances that the engine you rebuilt has a gasket or seal leak. Use these plate kits to seal off the exhaust ports allowing you to pressurize the entire system to check for leaks. Kit includes custom made ¼†Aluminum plates, rubber gaskets, and hardware shown. A few minutes on the bench can save hours of work later trying to correct leaks after the engine is back on the aircraft. See Articles series Part #59 “Diagnostic Leak Testing†in the rear of the CPS Catalog or online in our webstore for procedures.
