Have you seen the price per L in Europe for it already? Curious if it's the same as normal avgas?

Would you but an IO-360 with 550 hours on it since overhaul that was done 15 years ago? Considering it’s impossible to see the cam and lifters during inspection?

Talk to Justus at ACG Aircraft in Germany.

Had the same and it was a blocked injector. EGT will never drop to zero unless the outside temp is 0c or below. I stuck valve in the closed position will increase EGT and since your compression is good, it can't be stuck in the open position. If you are really worried about a valve than boroscop the cyl but I would clean the injector.

How many hours since it was done? Could also be just hot cyl breaking in. How high is the temp?

Just wanted to thank you for your help. I found out that the servo ground wire came out of the crimp ring. I installed a new ring and all is good!

@Jake@BevanAviation I get it now. So the rocker switch (up/down) on the AP works, also the electric trim works (although it obviously disconnects the AP). I guess the trim servo works? Also the ground test pass so the AP thinks it is all okay. I don’t get the slow oscillation, it’s just like you never pressed the alt hold. I have to hand fly (push/pull the yoke) to keep altitude. Any idea where to go from here?

@Jake@BevanAviation thank you for the explanation. It just stays at whatever attitude the plane is prior to pressing the alt hold button. I was climbing at 600fpm and when I decided to level off, I pressed it but noticed that the plane was still climbing. After that I tried a few more time while fairly level but it was like hand flying, didn't oscillate or hard pitch. What do you mean by "tach generator"? the same one that is on the engine for the RPM gauge??

Meant to say 2017, not 2007

It doesn’t hold the altitude when I press the alt hold button. Used to hold it well when pressed.

It was installed in 2007 as far as I can tell.

I don't have pre select but the interesting thing is that I got a message on my Garmin GPS "Pressure altitude source inop or connection lost” so I thought it could be related. I have a G5 and GTX330 with Alt so I was wondering if it was getting the alt source from one of them.

I will have to check if mine are (I have two altimeters) are encoding or not.

I am curious where does the KAP AP get its alt source (GPS, G5 or transponder baro?)? Went flying today and noticed the alt hold wasn’t working. Everything else was working fine (heading bug, electric trim etc). I am wondering if something got lose in the connections. The AP pass the preflight test so it all seems fine.

Why not let PMM in Belgium rebuild it?
