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.

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 -GV In a message dated 01/17/11 20:37:04 Pacific Standard Time, dean.psiropoulos@verizon.net writes: 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.
