I may be wrong, but it seems to me the metal case on an aviation oil filter is thicker than an automotive oil filter, which seems to be about the same thickness as a beer can. I would be interested in hearing whether you can use this technique on an aviation oil filter.

You may be better with hard assets than fiat money in an account somewhere. When things collapse, at least you'll have something to sell. I say buy it. How many more medicals do you have in you? Go Basic? Maybe. But what happens if you get a TIA. Minimum of 2 years downtime. As they say...

I had my 430W refurbished (which raises the question, when it was originally made, was it "furbished"?). It was done by G, but has to go through a dealer. SA was the dealer, and everything went smootly.

Agreed. I might very well have done the same thing. If the wheels make it off the ground, I would likely have nursed it along with the idea that the engine would smooth out and everything would be fine. It probably won't. We are all "mission oriented." When somebody calls and asks me to...

I have a Milwaukee M18 compressor. I don't have 120v in the hangar, so my options were limited. I have a small generator, but it didn't have the guts to run the small HF compressor I bought. The inrush current kept on blowing out the starting cap. The Milwaukee compressor is quite good, and...

Yes, and I think you were right. It was intermittent only to the extent that it occurred only in one distinct phase of flight. Also, I often leave the prop out as long as possible. If I push the prop in early I think it is more likely to windmill and drive the engine.

In speaking with a long-time IA, he said it sounds like the prop is overdriving the engine. That makes sense. First, all I have to do is add a few hundred RPMs and the EGTs drop right back down. Second, the rest of the flight is all normal, so I don't see electrical gremlins as a cause.

Here's a business idea. Print up some poster sized paper that is an image of empty steam gauge holes with wires coming out. Park and pull out the poster. Put a little masking tape on the paper and tape it over your panel. All the thief sees is a ragged out panel with most of the goodies...

I'm at sea level, so I lean aggressively on the ground. The idea being that if the mixture is very lean, not only do you avoid fouling, but if you forget and apply takeoff power without richening the mixture, the engine will stall out.

It may have been higher than when I was on the ground at idle, but it was most certainly lower than at cruise where the EGTs weren't as high. On descent I was not much higher than idle on RPM, and MP was low.

If it were an electrical anomaly, why wouldn't all functions of the JPI be affected? The CHTs remain rock stable, as are all of the other measurements. I don't see how grounding, RFI or any other electrical situation could affect only the EGTs while the balance of the the measurements are...

No altitude compensating fuel pump to my knowledge. Besides, it's just a 1k ft descent from pattern altitude.

This is the flight I posted about. I wanted to change the oil, so I took off and went around the pattern once. What you see are 6 EGTs/CHTs plotted against altitude. At 13 minutes the aircraft climbed to pattern altitude. At 18 minutes the descent begins. While the descent is taking place...

You should be very proud. That is a big deal.

There is a Simple Green Aviation formula. The owner of the company is a pilot and he had another formula made that passed the Army standards for corrosion. That said, I don't think the SG variations are all that great. If it's just oil, sometimes I use WD40 or mineral spirits. I have some...

I am certain there will be a mobile Starlink receiver. All we have to do is slow down to highway speeds or find a way to spoof speed and/or altitude.

Don't worry. Someone will be along to steal those soon.

I'm going to try that next time.

SA said they've seen RFI interference with some engine monitors. Not the sensors, the box itself. But that's not a satisfying explanation, since if I bump the throttle up a few hundred RPMs the EGTs return smoothly and uniformly down to the blue.

I did. SA was baffled. Perhaps some sort of RF interference. It has happened often. The first time I was landing to get gas. I thought perhaps I had run out of gas, and the mixture was leaning because there was simply not enough flow. I had many gallons, so it was not exhaustion. Fuel...
