Picture embed looks fine. You can check before posting by using the "preview" button.
Note that they also suggest to check for metal in the oil filter. Ae the previous entries from the same plane? If so, that's worth examining.

Re: Questions about pitting in the camshaft
I reread the original post and realize I misread it. The indication of real trouble is not a bit of metal found in an oil analysis but the presence of iron/steel particlaes found in the oil filter. The latter is what I inferred. There is no mention one way or another about the oil filter having bee...

Re: Questions about pitting in the camshaft
Roller tappets are supposed to be an improvement. I think they are now standard on Lycomings. Instead of the tappets and lobes sliding across each other they roll.

Re: Questions about pitting in the camshaft
The way Lycomings are built examining the cam/followers requires cylinder removal at the least to get access. There won'y be any outward indications of this wear problem until it's extremely advanced. I've been through this. Inactivity is the culprit and this engine has seen plenty. I would do a co...

Re: Questions about pitting in the camshaft
You will have to remove multiple cylinders to inspect all six camshaft lobes. In my case it was only two of the six lobes. Some pictures after teardown:

Re: Lightspeed Delta Zulu
Unique experience today. A firmware update (???) for the Delta Zulu :scratch: I decided to check CO history. It peaked somewhere at 8 PPM. But it never shows that high when I check it in flight. I'm guessing it happened sometime when idling on the ground where the exhaust isn't ripped away with the ...

Re: Help!!! Prop Strike questions for a Diamond DA40
This SB has grown much more stringent over the years as well as more burdensome to comply with. In 2002 we had a rock ding that apparently caused a small puncture/crack in the leading edge of one blade. The nature of an MT prop is such had to be removed so it could be disassembled and the blade repa...
