John, do you have a warran= ty or builder info for that engine?  Metal should not be increasing so I= would heed Howard's advice until you figure it out.

Hello all,

 

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

&nbs= p;

I have about 60 hours on the engine now a= nd it runs quite well.  Due to the worries related to Fred Moreno=E2=80= =99s 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= =E2=80=99ve been monitoring it closely and have been doing frequent oil chan= ges to look for developing problems. 

 

All parameters have been go= od except there was silicone early on in the oil (first change was at 5 hour= s then at about 15, then at 35 hours and another later on.) and a slight ele= vation in aluminum.  Second oil change still have the silicon and alumi= num was much higher.  Also there was a bit of metal flakes in the filte= r element =E2=80=93 non magnetic.  Last oil change was even higher alum= inum 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 oilp= inion in Oklahoma) and he expressed concern and advised to quit flying until= the problem is figured out. 

 

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

 

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

 

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

&= nbsp;

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

<= o:p> 

Does anyone have a suggestion abo= ut how to  sleuth out this problem?
