(VPS 0533-4, 08/19/2005), Outbound message X-Antivirus-Status: Clean Yes, I replace the oil seal o-rings. Yeah, it was smoking when I got it. = Very low compression on one rotor. Replaced parts with Tracy's overhaul kit. = Bearings in rotors were not replace but looked ok and measured fine. New apex seals and side seals. I didn't replace the metal oil rings on the rotors as they looked fine. How= critical are these anyway and what are the symptoms of failure/damage?

Thanks >>=A0to all previous replies on the crank angle sensor/TDC >>=A0settings I was able to get it to crank and run. Now for the >>=A0diagnosis of my present problem: Engine starts and idles with a >>=A0slight >>=A0amount of smoking. As the engine warms up and I increase the RPM >>=A0I get a considerable amount of smoke. The smoke does >>=A0not smell "sweet" like it is burning coolant but maybe it smells >>=A0different in a rotary. Smoke is white not black. With limited >>=A0running >>=A0I haven't noticed a drop in the coolant or coolant in the oil. >>=A0Before I pull the engine and go thru it again I would like to >>=A0pinpoint the >>=A0problem before teardown. I thought I was careful about the o- >>=A0rings. I used Hylomar for the grooves as per Bruce Turrentine's >>=A0tape >>=A0to keep them in the grooves. Am I getting oil past the oil o- >>=A0rings? Other sources or causes for my smoke? Tests I need to run? >>=A0Help!
