Subject: [LML] Re: Performance Engine TSIO 550 Why has the FAA not shut these guys (Performance Aero Engines Inc.) down ? ? ----- Original Message ----- Sent: Wednesday, August 29, 2012 5:52 AM Subject: Re: [LML] Performance Engine TSIO 550 In my opinion, SOON, should be NOW, no kidding I had an Performance Engine on my Velocity and the bolts came of from the cylinders as they were torqued wrong. I had 2 bolts coming off the engine and going through the propeller. Thank god they actually damaged the prop so we had to start looking for the why....well it was ugly. This engine had only 200 hours on it. Oh and I did managed to talk to them 1 time, and they came with some BS story that the bolt might broke off because of some gas trapped inside the metal......sure.....and they believe in Santa too lol We had a rocker failure before (at 100 hours) and for me this engine was a nightmare. Definitely do the overhaul, get the engine back to specs, and forget about the 400HP they claim....is BS anyway, as you will never use this, not even on takeoff as you really do not need 400hp to take off in a IV-p So do yourself and your family a favor......

Thanks to the many who responded on List and off to my question. Still haven’t come to a decision what to ultimately do, but it’s almost 100% assured there is an engine tear down in my future – and SOON. Lots of constructive input that I appreciate immensely. It’s confirmed what we all have known for few years. Almost all (good) roads lead to Barrett Performance Engines. To all that need a good engine rebuilder, I had my Glasair engine rebuilt by LyCom in Vasilia, CA...When it was rebuilt and installed, thats when I was glad they did the rebuild...Ran so smooth and with increased power, same amount of gallons per hour and increase in speed...From 183kts to 191 kts...I was very happy, they delivered what they promised...That's my 2 cents In a message dated 8/26/2012 7:54:24 A.M.

With zero time on it, I sent it to Barrett Precision Engines http://www.bpaengines.com/site.html in Tulsa for complete teardown and overhaul due to the problems that many others have had with Performance. Even if no metal was showing up, you’ll never have any confidence in your engine. I believe that everyone on the list who has dealt with Barrett will give them a strong recommendation. Bite the bullet and send it to Barrett (maybe you’ll get a family discount? :-) N6ZQ IV under construction Sent: Saturday, August 25, 2012 8:56 AM Subject: [LML] Performance Engine TSIO 550 I have a quandary with this engine and am hoping to get some help in solving it. I have about 60 hours on the engine now and it runs quite well. Due to the worries related to Fred Moreno’s problem with his engine and various others I was highly concerned about the safety of operating my L-IVP with this power plant. To that end I’ve been monitoring it closely and have been doing frequent oil changes to look for developing problems. All parameters have been good except there was silicone early on in the oil (first change was at 5 hours then at about 15, then at 35 hours and another later on.) and a slight elevation in aluminum. Second oil change still have the silicon and aluminum was much higher. Also there was a bit of metal flakes in the filter element – non magnetic. Last oil change was even higher aluminum and silicon still elevated. The oil filter element looked like it had glitter applied to it. Blackstone has been doing the oil analysis. I sent the last filter element to Howard Fenton (2nd oilpinion in Oklahoma) and he expressed concern and advised to quit flying until the problem is figured out. He says the only metal found is aluminum and he’s never seen or heard of that. Always in his experience there would be some other metal showing up in excess as well because there isn’t a place in the engine he’s aware of the aluminum rubs against aluminum. I discovered after the second oil change that the alternate air door was not closing completely and that probably explains the silicon. I did compression check a couple of days ago and got normal readings – 80/75 to 77. I don’t have a plan about how to trouble shoot the origin of this metal. I notice that cylinder #5 runs hottest egt’s during warmup but other than that I can’t think of anything out of the ordinary. Does anyone have a suggestion about how to sleuth out this problem?
