Fellow Listers:



My RV-6A has been flying for a couple years now and since I have the

repairman's certificate I've been doing the annuals and maintenance. My

question is on cutting open the oil filter after an oil change.  Since I've

never owned an airplane before much less maintained one this exercise has me

wondering:



After the first few oil changes on a new/overhauled engine, do you keep

cutting open the filters and inspecting the element? 



Or is inspecting the element not as important as in the first hours after

break in?



Those of you that do cut open the oil filter at every oil change, do you

ever see fine particles in the filter element? 



If yes, how often do you see these particles? 



What color are the particles? 



How large would the particles have to be to be of concern?



Did you notice more of these particles after switching from 50 weight break

in mineral oil to say... 20W-50 ashless dispersant? 



How many folks do oil analysis in addition to cutting open the filter?



If the oil analysis says no problem but there are a small amount of fine

particles in the filter do you continue to fly?



If you have fine particles in the filter would you take them to your local

mechanic and have him/her look them over? Or???



I've done lots of work on cars but never cut open the automotive filters so

I don't know if fine particles would be present at every change.  I don't

want to be paranoid about this but if a problem can be caught early by

cutting open the filter EVERY TIME then I want to be sure to continue doing

that. Otherwise I'll dispense with that messy exercise. Thanks.

Dean-

  

 My opinions only.  Do all this at every oil and filter change and you will feel much better about flying yourself and your loved ones over the pointy bits and you will likely grow to be an old man.  There are many early signs of engine wear both normal and abbynormal that can be easily discerned by doing same.  Both oil analysis and filter examination are needed IMO.  Remember, as in a car, when our engine quits we still pull over to the curb, but the curb is a lot further down.

  

 Go to the Blackstone Labs website and get up to speed on this procedure

Dean,

  

 You definitely want to cut open the filter every time you replace it.  If everything is OK then you will find a few black particles that are carbon and easily break up wth your fingers.  If you see anything shiny try to pick it up with a magnet.  If it doesn't pick up then it aluminum and not to worry about unless it is large particles.  If it does pick up thn it is steel.  if they are very small particles and there is not large quantities of them then make note ad carry on.   If there are are quantities of fine particles or a few large chucks then you need to investigate.

  

 Oil analysis is also a ver cheap good thing to do.  It finds wear that can't be caught by the oil filter or the eye (i.e, chromium).  What is important is that it sets up a trend that is important to find wear before it becomes a major problem.  For example, on Joe's plane, the analysis has shown that he is getting a cylinder wear that is corresponding with one cylinder just starting to lose a little compression.  Right now it is not something we need to deal with but it is showing that the cylinder probably will not make TBO times.  

  

 I hope you are enjoying the Florida weather and some good flying.

One more thing - check the pickup screen. Big chunks       won't show up in the oil filter because the pickup screen got them       first. If there's chunks in the pickup screen, you may have a       right now kind of problem that looking in the filter and oil       analysis might not show up.
