On Aug 11, I made a post about my crushed Kelly oil filter and  

included pictures.  I want to set the record straight.  The failed  

filter was the wrong filter for the engine.   I am both sorry for and  

embarrassed by my mistake.  The difference between the correct filter 

(48108-1) and the incorrect filter(48110) is an internal oil bypass  

valve in the correct filter.  I was unaware until about a week ago  

that  there was any substantive difference between the two filters  

other than the 108 had female threads and the 110 had male  

threading.   I'll explain how all of this happened.



I was at home and going to do an Aircraft Spruce order and remembered  

that I needed more oil filters.  I didn't remember the filter number  

so I looked it up in the A/C Spruce catalog where the IO-540 was  

listed under the 110 filter.  When I got the 110's it was obvious  

that one filter(110) was male and the other filter (108) female.   

That wasn't a big problem because the male adapter for the ECI angled  

filter adapter came off  with the 108 filter.  I figured there was no  

sense of messing around with the male adapter if it comes off easily-- 

just use the filter with the male threading built in.  So I put the  

110 filter on and flew with no indications that there were any  

problems until I took it off and found the filter media crushed  

inside the metal shell. This was around OSH time so I asked Kelly  

what might be the problem.  The very short answer from them was the  

engine.  I also asked the Mattituck guy what might be the problem.   

His answer was the filter.  I emailed the Light Plane Maintenance  

editor and asked the same question and his answer was the filter.  I  

also had emails from people on the RV-10 list telling me to check the  

engine and hoses which I did.  Nothing seemed amiss with the engine,  

hoses, or oil pressure.  Since I could find nothing wrong with the  

engine and I ordered new Champion filters and put a new Champ 110  

on.  I checked it regularly and it wasn't looking distressed at all.   

There were no signs of crushing.   I thought my problems were over.



While all of this was going on Kim Santerre of LPM wanted pictures of  

my crushed filter and I sent them.  He was doing an article in LPM on  

defective filters and my problem fit right in.   The article appeared  

last month in LPM with my filter pictures prominently on the cover.   

Kelly was not happy about the coverage and started discussions with  

LPM.  While digging deeper to address Kelly's concerns, Santerre  

contacted Mattituck and found out that my model engine ships with the  

ECI angle adapter and should have a 108 filter because the adapter  

has no bypass valve.  Santerre thought that I must have the straight  

adapter with the integral oil bypass valve since I was using the 110  

filter. That's when I found out about the real difference between a  

108 and a 110.  It was very embarrassing to tell him that I had an  

angled adapter and I should have been using the 108 filter.   A  

clarification is to appear in the next issue of LPM.  Kim Santerre  

has been very gracious during all of this fiasco.



Apparently I'm not the only owner who has been confused about the the  

108 and 110 filters.  Mattituck has a warning that they now ship with  

the ECI adapter equipped engines.  My engine was shipped in July,  

2007 and the warning came out in Oct 2007.  See the attachment.   I  

think that ECI has a poor adapter design  since it is possible to  

remove the male threading  with no difficulty.  A fixed male thread  

design would make it impossible to use the wrong filter.  I still  

think that the Champion filter is superior to the Kelly since it  

survived in a situation where the Kelly failed although I'm sure the  

Kelly will work just fine in the proper installation.

Wow Sheldon, thanks for the update on the situation. It's actually

comforting to know that it was something so simple yet so confusing,

and not some other wild engine problem.



For the builders out there, make sure you read ALL of the line

in his post....don't just skim in.  The 48110 filter is indeed

the right filter for many of us.  And, for people who have

the adapter from ECI like Sheldon does, the 48108 is the right

one.  So don't just skim the post without coming away with the

full understanding, or you may inadvertently get the wrong

filter.



Sheldon, do you know if ECI is basically the ONLY adapter that

we have to worry about this with?  I know in my case I just

have the standard straight adapter, and I need to use the

48110 male thread filter.  But I'm curious....does the B&C

or any other filter adapter bring potential issues for other

builders?  Up until now, I basically thought the 48110 was

the "only" filter for our engines.  Especially when you

see this page:

http://www.aircraftspruce.com/pdf/2010Individual/Cat10304.pdf



The 48108 doesn't even list a 540 model...but as you found,

that's not the same if you run the ECI adapter.



Thanks for the post...I know a few TMX engine buyers, so

I'm sure it'll be something they'll want to know.

I can give you another reference point. Our stock 182 always used the 48110 and the Cessna oil filter adaptor, until the last overhaul, when the adaptor was replaced with the latest version, and the filter changed to a 48108. At least, the shop put a sticker on the firewall, warning  "Use only filters with an internal relief valve".



So there are other adaptors that need the 48108 filter.

The B&C angled adapter also uses the 48108.  Their's actually has the filter number engraved and the adapter.

Sheldon,

  Thanks for the valuable info, but more importantly thanks for owning up to

the error, a trait not seen nearly often enough in this day and age!
