2200 Hour Report and Pics
 
Just back from Big Sky, Teddy Roosevelt NP, and Iowa Trips. Hobbs flipped over 2,200, so I dropped the oil.

Filter and screen had some carbon chunks, and the filter had just a tiny amount of fuzz attracted to a neodymium magnet.

Compressions were 77-78-77-77. Valves looked pretty good!

We are going to continue to run and watch her carefully. Local A&P says many O-320s will go 2,600 hrs+ if they get flown.

The combustion side is looking great, I assume the oil sample analyses remaining consistent?

Analysis
 
Hi Bill,

I have not pulled a sample for analysis in a bit. I will do that.

Nice looking valves Pete. Keep it running don't stop. Watch closely do not abuse it. I personally know a motor like yours making double time +. ;)

What Bore scope?
 
I bet you have been asked before, but those are some very good photos. What bore scope are you using? PC/ android or Iphone /Mac to record them?

long live the 320!

... wild guess, a VA-400 or 800?

Long live all the used engines ;)

The pipeline patrol company at our airport runs their O-320's 4,000 hours. No problems at overhaul. They do oil analysis, and all the accessories get changed on a time schedule. I looked at one the other day that had over 3,000 hours on it and it was still getting 12-13 hours out of a quart of oil with the original cylinders. You can imagine how much they fly, and that is probably the main reason the engines are going so far.

Forget Lean or green, I'd say those valves are CLEAN of peak :D

2300 Hour report!
 
Not much has changed at 2300 hours. She is still running great.
  • Filter and screen had some carbon chunks, nothing more.
  • Compression #'s were 77-76-77-78 with a warm engine. Valves looked pretty good!
  • As mentioned previously - We are going to continue to run and watch her carefully.

Valve Porn - the cheapo camera was not super sharp this time, but did the trick
