tigers2007 Posted August 15, 2019 Report Share Posted August 15, 2019 I’d bet this oil screen hasn’t been inspected in a decade or two. I guess I could scour the engine logs. I think it has 2300 SMOH. 5/8” wrench for those wondering. Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Hank Posted August 15, 2019 Report Share Posted August 15, 2019 My new IA this year, who has touched my plane for the last time [and will never be within 1000' if I have any say] thought that my oil screen would be in horrible shape since it still had the tag from when the engine was OHed in 2003. So he pulled it, and found "zippo" in the screen or in the sump near it. Guess that 50-hour oil change is good for something after all, and that big filter that barely fits on the rear of the engine actually works . . . . . YMMV, no animals were harmed in the production of this post, guns don't kill people, forks don't make people fat, supersize me, caveat emptor, etc., etc. No representation is made that the quality of analysis in this post is any greater than the quality of analysis in any other posts.

bradp Posted August 15, 2019 Report Share Posted August 15, 2019 Did you find gold during your panning? 1 Quote Link to comment Share on other sites More sharing options...
tigers2007 Posted August 15, 2019 Author Report Share Posted August 15, 2019 I torqued it 135 degrees and had the copper washer seam face the pan (per the Superior manual). Hardest part was safety wiring it. It took me two tries as I didn’t like the first one. Grab like 32” or so and feed it from the port side about three inches and then go to the starboard side and reach your arm through the top like like in the photo above and guide the tip through the strainer nut’s drilled hole. You can then take a needle nose pliers and pull the rest of the wire through. Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
RobertGary1 Posted August 15, 2019 Report Share Posted August 15, 2019 I just safety wire it by hand because it’s hard to get a tool in there. Otherwise it’s not bad. -Robert Quote Link to comment Share on other sites More sharing options...
carusoam Posted August 15, 2019 Report Share Posted August 15, 2019 Great pics, Tigers..! Doesn’t look like you found the cam shaft in there... But, there is the start of something in there. They look like diamond seeds.... may take a millennium for them to finish the conversion... PP thoughts, not a mechanic...

RobertGary1 Posted August 15, 2019 Report Share Posted August 15, 2019 Yea that’s far more than I’d seen before! -Robert Quote Link to comment Share on other sites More sharing options...
tigers2007 Posted August 15, 2019 Author Report Share Posted August 15, 2019 I’m guessing the big black chunks are carbon deposits? Moderator/Admin: can you change the “A1B” to “A1D” in the title please. Says I don’t have permission to change it.

carusoam Posted August 15, 2019 Report Share Posted August 15, 2019 Tigers, the title can be edited like everything else... by the person who wrote it... The carbon chunks are the diamond seeds... they may have shapes that can indicate where they were formed... If big enough they may be forming in the valve guides where oil has difficulty circulating... and it is hot enough to break down the oil... PP thoughts from my M20C experience...

Hank, I don’t know the whole story, but it sounds like he at least did check a screen that all the other neglected. Clarence Quote Link to comment Share on other sites More sharing options...

Clarence Yes, he checked the screen. He did other things, including ordering parts, without informing me. Some work I had to take to an MSC to be redone correctly. Ex.: he didn't like how my nose gear door closed, so he "adjusted" it to close better. But apparently didn't test it on jacks; it went up with the normal thump, but the loud bangs during extension were audible through my headset, to say nothing of jerky rudder pedal movement. Joey Cole put her on jacks and said he was surprised the gear even came down . . . . He replaced all control surface rod ends, even though I asked him not to since he didn't have a set of travel boards. Joey rerigged them; the elevator was set for max 15° up, but down went off the scale (>25°). Glad I was able to take off! He replaced "badly corroded" one year old wheel bearing races (at $100 each plus 5 hours labor) after I told him to not replace the one year old bearings for 5 hours labor; the removed parts he gave me are fine, and he never mentioned it until discussing the bill. The annual took ten weeks . . . . . If you want the rest of the story, let's do it by PM. Glad the OP now has a clean screen. Regular oil changes should keep it clean for a long time. Mine was apparently not checked by the 4 different IAs doing annuals from 2003-2018, nothing found on inspection in 2019. 1 Quote Link to comment Share on other sites More sharing options...
RobertGary1 Posted August 16, 2019 Report Share Posted August 16, 2019 In most states if a car mechanic does work not authorized its free. I always wondered why we don't have the same rule for aircraft. -Robert Quote Link to comment Share on other sites More sharing options...
