Overhauled in 1994. Wasn't that the timeframe for the poor metallurgy cams and lifters?

Leaning until rough and then enriching until smooth, usually results in a close to peak egt setting. At least it did in my IO360 equipped Mooney. In my carbureted 310, it never gets rough, it simply quits. THAT happens around 40 LOP. To be brutally honest, you really have no idea what your engine is doing without an engine monitor. If you have no plans to install one, just listen to your motor. It will tell you when it's happy and it will also tell you when it's angry. Your single-point CHT and EGT are only giving you 1/4 of the story. But at least it's part of the story. Yes, if I remember correctly, those marks are 25 degree marks. There's really nothing you can do to hurt these engines when you're below 65% power. I changed the way I operate my engines after going to the lycoming seminar at Oshkosh. 65% and below: peak, above 65%: 100 ROP. This came from a Bonanza owner with 2200 hours on a 520 and never been topped. Either he had the unicorn 520 or he was doing something right.... or both.

I may have missed it, but did you mention what your oil pressure was indicating while you were flying the airplane and having this problem with the prop? Sent from my Pixel 2 XL using Tapatalk

You're supposed to pre-flight?? Seriously though, great find! Sent from my Pixel 2 XL using Tapatalk

Those same pilots are probably used to flying airspeed from the B-17 days. [emoji23][emoji23] I'm sure a moving map and autopilot were both considered crutches at one time. Sent from my Pixel 2 XL using Tapatalk

If it was a short, it would trip immediately. It sounds like the switches / breakers are getting tired. This problem is fairly common in the older planes. in addition, if your landing light switch is next to your nav light switch, it may be producing heat which can cause both trip. Keep in mind, that incandescent landing light is pulling 18 amps. [emoji44]. And your navlights are pulling 7.5. The first thing I would do is switch out your landing light to an LED and do the same with your nav lights. There are a few manufacturers who make LED nav lights that are direct replacements for the bayonet bulbs. Check out Aerolites. This will reduce the load on your system dramatically.

Making Sparks good.... No make Sparks, bad. Sent from my Pixel 2 XL using Tapatalk

It makes kind of a bad situation with TCAS as well. if the airplane thinks you are somewhere that you are not and it commands a climb or a decent, you could end up hitting the other airplane. I have personally seen this on three individual instances. Sent from my Pixel 2 XL using Tapatalk

Just ordered a CHT probe from Insight Avionics. $128.00 which seems right in line with any other CHT probe however, I was also charged $23 for freight. Seriously? For a single CHT probe? I have played this aircraft ownership game for quite some time now and I get it, but really? You can't stick it in a bubble pouch and throw it in the mail? Sent from my Pixel 2 XL using Tapatalk

Because you're a rich airplane owner! Make sure you get the TSO prop lock because you have a certified airplane. [emoji1787][emoji1787][emoji1787] Sent from my Pixel 2 XL using Tapatalk

The only way to really determine if the gate is no functioning is to put a manual oil pressure gauge on it. Your mechanic should be able to do this no problem. I did this when I first got my airplane that was showing high oil pressure. The manual gauge showed pressure was normal. My problem was the gauge, but you really need to know for sure.

This is what a partially plugged injector looks like. This is an IO360. It caught my attention flying home one night when the EGT jumped and the CHT decreased together for no apparent reason. When I pulled the injector out, I found the tiniest particle of something in the injector. Cleaned it out and it cleared right up. https://www.savvyanalysis.com/flight/2430228/25d50e01-a31c-48ee-a33b-2b02c03e9b7e The event starts around 22:40

Yes, that's the profile.

I know some have a rhythmic lope to them, but mine was just erratic. Once the fuel leak (leaking fuel strainer) was fixed, she idled very smooth.

I think you have an intake leak on number 1. How does the plane idle? Nice and smooth, or a little rough? Your number 1 EGT is is 100° cooler at idle. As you advance the throttle, it joins the rest at the party until you pull it back to idle for landing and taxi. I just had this problem. Mine was a but more severe where cylinders 5 and 6 would not participate during idle when it was cold. I found a massive intake leak at the balance tube to intake riser joint (Continental thing) Your IO360 should purr in the idle, if it doesn't there's a problem. I chased an erratic idle for three years in my Mooney. Turned out to be an airframe-side fuel leak... but I digress.... My suggestion is to do Savvy's intake leak flight test profile. I bet you will find you find one or more intake leaks. I had repeated problems with intake gaskets until I coated them with Permatex #3 aviation sealer. That finally did the trick.

That just looks expensive Sent from my Pixel 2 XL using Tapatalk

I think, "installer" might be a bit generous. Sent from my Pixel 2 XL using Tapatalk

Things appear to be grounded everywhere. The plane seems to be ground loop heaven. [emoji848] Sent from my Pixel 2 XL using Tapatalk
