Yea need some clarity, throttel side is the same side as the oil resovior and a pretty common place for oil to be especially if rolled ect.

smoking

still having oil residue up top on trottle side.sled started smoking bad from oil being dumped out exhaust. think rollover valve was coming on during normall conditions, and causing exsesive presure and blowing the oil past turbo seals. unplugged valve and seemed to eleveate problem, is this possable. also what rpm is everyone running.

85-8900 The hp pretty much plateaus after 8500, large top end power band. The rpms seem to jump all over on top end regardless. its not like a 2 stroke where 50rpm makes a huge difference. When looking at data logs you would be surprised how much it jumps around. At full boost its hard to stare at that small gauge for 3 seconds!
