All said, the 582 is far more likely to cold seize than a 670. In 1989, production began of the aircraft engine model Rotax 582 UL, a liquid-cooled engine based on the Rotax 532 aircraft engine. DESCRIPTION • 2-cylinder • 2-stroke liquid cooled engine with rotary valve intake Since the exhaust can move up, down, in and out with one bolt in place (may require some bending of the bracket at the engine attach point), your goal is to end up rotating the entire exhaust up and away from the engine, and thus from the wing’s material also. The steel expands much slower than the aluminum piston, which is why you need .003 to .006 piston to cylinder wall clearance. BRP donated a Rotax 912 iS Sport engine to Madiba Bay School of Flight, Port Elizabeth, Eastern Cape, South Africa, the flight school that achieved the first time between overhauls (TBO) of 2,000 hours on their Sling 2 equipped with a Rotax 912 iS engine.

The steel expands much slower than the aluminum piston, which is why you need .003 to .006 piston to cylinder wall clearance. If you fly in an area where you do a lot of cold weather flying (below 40 degrees) you may want to use enrichment chokes, which keep the engine running after the plunger primer starts it. A Gray Head with a ceramic top piston is as cold seizure proof as a Blue Head is with OEM pistons. Without a thermostat, the steel cylinders (with cool water passing through them) could not expand as fast as needed to keep up with the fast expansion of the aluminum pistons.
