Re: hot gas high temperature
Those are all excellent suggestions. I would add, there should also be a hand metering valve that feeds oil to the rotors. This oil essentially acts as a "seal" between the rotors and the casing. If there is not enough injection oil, you will have "blow by" and elevated discharge temperatures. Too much injection oil will reduce performance and use up hp. You might try opening this valve a bit more and seeing if oil temperatures drop noticeably when you do so.
Good luck,
