That was my thought also; = although I’d not like to think that the side seals in my engine are not too good = after only 150 hours.  I’m thinking it could also be influenced by = engine coolant temp – my cruise temp was running down around 140F at the = time I was seeing fairly rapid buildup of 2-stroke oil in the pan.  Cooler = side housing temp; more of the oil condensing there, maybe?

 

Would poor side seals also result = in loss of power?  My engine power has improved slightly over the past = couple years.

Group,

    One other opinion on this subject............The condition of the rotor oil side seals and = their

respective "O" rings probably is a = factor (along with the amount of 2 cycle oil used per gal of

fuel) that determines how much 2 cycle oil = ends up in the sump...........These seals essentially

scrape the sides of the rotors and if the = seals are worn past maximum or the "O" rings are

heat hardened they will let more fuel mix oil = past them into the sump............IMHO
