As I said previously, give your Wankel a decent "cook" and you warp the rotor housings. They are then "thow-aways". I'm also curious as to just when and why would you be considering rebuilding your engine (so you can re-use the TES O rings). seeing that if an engine rebuild is done peroperly in the first place, they seem to last for up to 20 years and 500,000 km if looked after (regular oil changes, clean coolant with corrosion inhibitor, and a well maintained air filter). There are basically only three things that will kill a rotary: 1. Serious Overheating (loss of coolant, drop a fan belt, water pump failure etc) 2. Running LOW or right out of oil (blown oil hose, filter cannister etc or just plain carelessness of the operator) 3. Swallowing something solid and obdurate (like a nut or a washer or a rock), or being fed dusty air (if you are silly enough not to run an aircleaner). I'd be interested on your take. Anyone else with some experience based reasons ?? Cheers, Leon --NextPart_Webmail_9m3u9jl4l_29136_1122262146_0 Content-Type: text/html Content-Transfer-Encoding: 8bit

Leon,

I will refer you to the manufacturer as I am not an expert on the subject.....
