Hello all,

 

I have a quandary with this engine and am hoping to = get some=20 help in solving it.

 

I have about 60 hours on the engine now and it runs = quite=20 well.  Due to the worries related to Fred Moreno=E2=80=99s problem = with his engine=20 and various others I was highly concerned about the safety of operating = my L-IVP=20 with this power plant.  To that end I=E2=80=99ve been monitoring it = closely and=20 have been doing frequent oil changes to look for developing = problems. =20

 

All parameters have been good except there was = silicone early=20 on in the oil (first change was at 5 hours then at about 15, then at 35 = hours=20 and another later on.) and a slight elevation in aluminum.  Second = oil=20 change still have the silicon and aluminum was much higher.  Also = there was=20 a bit of metal flakes in the filter element =E2=80=93 non = magnetic.  Last oil=20 change was even higher aluminum and silicon still elevated.  The = oil filter=20 element looked like it had glitter applied to it.  Blackstone has = been=20 doing the oil analysis.  I sent the last filter element to Howard = Fenton=20 (2nd oilpinion in Oklahoma) and he expressed concern and = advised to=20 quit flying until the problem is figured out. 

 

He says the only metal found is aluminum and = he=E2=80=99s never seen=20 or heard of that.  Always in his experience there would be some = other metal=20 showing up in excess as well because there isn=E2=80=99t a place in the = engine he=E2=80=99s=20 aware of the aluminum rubs against aluminum.

 

I discovered after the second oil change that the = alternate=20 air door was not closing completely and that probably explains the=20 silicon.

 

I did compression check a couple of days ago and = got normal=20 readings =E2=80=93 80/75 to 77.

 

I don=E2=80=99t have a plan about how to trouble = shoot the origin of=20 this metal.  I notice that cylinder #5 runs hottest egt=E2=80=99s = during warmup but=20 other than that I can=E2=80=99t think of anything out of the = ordinary.

 

Does anyone have a suggestion about how to  = sleuth out=20 this problem?
