We all live in fear of the FAA medical-Nazis Joe : )  Laura's fear that I might have had a heart attack instead of hypoxia (long story) cost me a session on the operating table while they scoped out my arteries.  Doc said they were "Clean as a whistle"   Wheww!
 
BTW, don't forget to check out the gear drive bearings during your investigation.  The rear main prop shaft bearing is a pressure fed bronze bearing and if it were galling it could account for the "gold strike" in the oil pan.  First check should be to insure that there is an oil passage hole through the bearing at the oil feed point on the drive.  There is one instance (Al G.'s) of a bearing that was missing the oil passage hole.   A spun bearing could account for no visible hole but this is very unlikely since the bearing is quadruple pinned and would probably seize long before it spun.

Thanx Rusty – I was gone for the weekend and away from email.

 

As you said, I won’t feel good about it until I know for sure what’s going on.  When I got back in town my wife graciously let me kiss her and then leave again for the airport to work on my engine. I started at about 5PM and at 7:30PM had it off the plane and in the back of my truck. Amazing.  It took months to get it all situated in the plane with all the hoses and wires and in a matter of a couple of hours it all comes undone!

 

I’m going to go see Atkins tomorrow and watch while they dissect the engine.  But, I also have another rotary I bought at a local junkyard a year or two ago and I’m slowly working on rebuilding that too. So, I’ll get my rebuild education at some point. But for this one, since I paid some substantial cash for that engine, I’d like to at least get 100hrs out of it!

 

Besides – I lost my medical temporarily.  If any of you have gone to a “sleep doctor” – you might want to conveniently forget that fact when you go to get your FAA medical renewed. I made the mistake of noting that and when asked about the outcome I said “mild sleep apnea”. Wrong thing to say.  Apparently the FAA doesn’t know the difference between mild sleep apnea and narcolepsy.  I spent all day today in a “Maintenance of Wakefulness Test”.  Essentially I sat in a dark room all day and tried to stay awake. I was successful so next week I can get a letter from the doctor and get it to the FAA and hopefully in 60 days or less I’ll get my medical back L

 

Thanx,

I dropped the pan today and there were a bunch of gold flakes in the pan. Not a huge amount overall but if I sloshed things into a corner it looked significant. So, pondering my next step. 

 

Hi Joe,

 

Did you drain the oil before dropping the pan?  I'm assuming the answer is yes.  If so, then draining the oil didn't get the flakes out.  If that's the case, then they could have been in there since day one, and you have no way of knowing.  

 

Did you get a chance to check the relief valve?  If you pulled the pan, and didn't unscrew that valve, your restraint is far greater than mine :-) 

 

As for what to do about the engine, it almost sounds like you're looking for an excuse to go through the engine to make sure all is well. If that's the case, and that's what will make you comfortable, then that's what you need to do.  End of dilemma.  See how easy that was :-)

 

I would further suggest that you do it yourself, with a copy of Bruce's video, rather than letting Atkins do it. It's not hard to do, and you'll be way more careful with it.  You can also use the opportunity to install the Bruce/RWS seals.  If you want a professional to go though it, then I'd recommend sending it to Bruce Turrentine.   

 

Cheers,

Rusty (26)
