Re: Very hot cly

The jug will be ruined if the valve isn't fixed. I would try to get a look at the valve seat before pulling the jug but even with a good borescope it can be difficult to spot what is causing the problem. A valve can be lapped without pulling the jug but if the seat is actually bad or the valve burne...

Re: Overheating and detonation

If the O-360 is stock it should run fine on premium unleaded. Aircraft have been doing it for years and the day is coming when we won't have a choice. Avoid alcohol ruined fuels if possible. Alcohol absorbs moisture and as a result can cause severe corrosion issues with aluminum. If you want to buy ...

Re: Is adding dual plugs worth it? 220 GPU?

You might check into E-Mag. It is an electronic ignition set up that replaces the mag. Shouldn't cost much more than adding a mag but should give you way better performance than mags. The E-mag produces it's own power once the engine is running and is designed to run with automotive spark plugs and ...

Re: EFI on 4 cyl?

Fuel injection is very common on aircraft but not EFI. They are just starting to play with it in aviation and it is VERY expensive over there. In fact, even just electronic ignition is generally allowed to only replace one magneto on a "certified" airframe. It is getting better but aviation is far b...

EFI on 4 cyl?

I did a search but didn't come up with much other than it had been done. I do not have any experience with EFI other than driving my truck and bass boat but I believe there are big gains to be had in performance and economy if it is feasible to install on an aircraft engine. Is there anyone willing ...

Re: EGT Probe 540 Lycoming.

Just 2 probes? I don't think I would mess with it at all. If you have a problem with a cylinder, 2 probes only give you about a 33% chance (less than 17% if only one probe) of being on the problem cylinder. The only reason I can think of for having them on airplanes is to lean the mixture for peak p...

Smoking wires come from too much resistance. I suspect bad connections if not bad wires. Make sure all the battery and ground connections are clean.

Re: Oil pump o-ring

If you are thinking the size can be fudged a little, you might try part number MS28775-240 (1/8 x 3.75 x 4). I haven't checked but I would think an auto parts or hydraulic shop would be able to match that up otherwise it's ~$1.25 plus shipping from aircraft vendors and should be readily available.

Re: O-520 oil pressure

Generally speaking, an aircraft engine will throw out the last quart of oil. That is why most people run the 520 with 10 or 11 quarts. Keebo had a good question with the clogged screen. I don't think you would see this problem on the main screen but there is a screen on the bottom of the pickup that...

Re: 520 Contential, no oil pressure

Personally, I would check it at max power and I would likely push the oil pressure up a little. 30-60 psi is the oil pressure range for a 520 at operational temps when taken from the 2-4-6 side of the engine. 10 psi is the minimum at idle. You may not get cold enough to see it where you are at but 1...

Re: Shutdown proceedure for IO520

If that process really only took a half a second it may be easier to 'adjust to' as you say, but realistically shutting down in that fashion does not happen that quickly in most cases. Consider if you will, that when you shut down your airplane, you have ground friction that has already stopped you...

Re: Shutdown proceedure for IO520

Another question would be... are you sure the mags are shutting off? Just because the switch is off doesn't mean they are grounded. They won't fire if they are spinning backwards but if they are sparking and still getting a little fuel it will act like it is dieseling.

Re: Shutdown proceedure for IO520

I agree with Dirtman and Digginfool, if it is dieseling then you are still getting fuel into the cylinders. Assuming you are using the stock injection system... are you using the mixture cutoff on the fuel servo (throttle body) or a cutoff in the line somewhere? Just killing the pump would still all...

Re: 520 Contential, no oil pressure

Not many possibilities on this. I would think the pump would pick up the oil without being primed, especially if it was installed with assembly lube and not a wore out piece of junk. Priming it should help but, if it is wore out, it isn't likely to hold it's prime if allowed to sit too long. The oth...

Re: 150 burning fuel

A stock O-320 (150 and the 160 hp versions) has a red line at 2700 rpm and burns close to 14 gph at that power setting. To see 8-10 gph it has to be running 2200-2300 rpm or somewhere between 65% and 75% power. That is from the engine documentation. If this engine can turn 3,000 rpm (110% power) and...
