Our Performance Engine had all six pistons fail in the first 40= hours, a case crack was discovered shortly thereafter.  It then went = to Barrett Precision Engines for a complete teardown inspection.  Cons= idering history, a trip to Barrett could be the best money you have spent o= n your plane.

Hello all,<= /div> =0A
 
=0A
I have a quandary with this engine and am hoping to= get some =0Ahelp in solving it.
=0A
 
=0A
I have about 60 ho= urs on the engine now and it runs quite =0Awell.  Due to the worries r= elated to Fred Moreno=E2=80=99s problem with his engine =0Aand various othe= rs I was highly concerned about the safety of operating my L-IVP =0Awith th= is power plant.  To that end I=E2=80=99ve been monitoring it closely a= nd =0Ahave been doing frequent oil changes to look for developing problems.=   =0A
=0A
 
=0AAll parameters have been good except the= re was silicone early =0Aon in the oil (first change was at 5 hours then at= about 15, then at 35 hours =0Aand another later on.) and a slight elevatio= n in aluminum.  Second oil =0Achange still have the silicon and alumin= um was much higher.  Also there was =0Aa bit of metal flakes in the fi= lter element =E2=80=93 non magnetic.  Last oil =0Achange was even high= er aluminum and silicon still elevated.  The oil filter =0Aelement loo= ked like it had glitter applied to it.  Blackstone has been =0Adoing t= he oil analysis.  I sent the last filter element to Howard Fenton =0A(= 2nd oilpinion in Oklahoma) and he expressed concern and advised = to =0Aquit flying until the problem is figured out.

He says the only metal found is aluminum and he=E2=80=99s never see= n =0Aor heard of that.  Always in his experience there would be some o= ther metal =0Ashowing up in excess as well because there isn=E2=80=99t a pl= ace in the engine he=E2=80=99s =0Aaware of the aluminum rubs against alumin= um.
=0A
 
=0A
I discovered after the second oil change that = the alternate =0Aair door was not closing completely and that probably expl= ains the =0Asilicon.
=0A
 <= /div>=0A
I did compression check a coup= le of days ago and got normal =0Areadings =E2=80=93 80/75 to 77.
=0A<= div class=3D"yiv127850760MsoNormal">  
=0A
I don=E2=80=99t have a plan about how to trouble shoot the or= igin of =0Athis metal.  I notice that cylinder #5 runs hottest egt=E2= =80=99s during warmup but =0Aother than that I can=E2=80=99t think of anyth= ing out of the ordinary.
=0A
&nb= sp;
=0A
Does anyone have a suggest= ion about how to  sleuth out =0Athis problem?
