From: FLYaDIVE Hello Im; If you think about it, why should he pay attention - He is doing what he feels is acceptable. Should the engine sit without doing ANYTHING? I woul d say that is even worse. Until they come up with nano-bots to travel around inside the engine and report as to REALLY see what is going on you can ONLY do what makes YOU feel good. As for venting the steam? It would be a SIMPLE test to really say what is in the steam. Get some LITMUS PAPER... Go flying for say an hour. Land and Open the Oil Cap and hold the Litmus Paper in the steam. By doing a comparison with the Litmus Chart you will get an idea of the pH of the steam. If it is just water you have to consider what will happen when the engine cools and what the humidity of the day is. You may draw in more humidity than you just let out. And what is escaping is ONLY what is in the area of the tube and is light enough to travel up the tube. Do you know what sits ABOVE the height of th e pick-up of the tube? The CAM. The Internet has a very short memory. A short time back I posted a lengthy synopsis of Corrosion & Rust on an engine that sat dissembled for slightly over a year. NO PROTECTION other than a plastic sheet draped over it. Ya know how much Corrosion and rust was formed after a year? NONE! Now someone may say that was because of the oil that was being used. Such as Exxon Elite. The answer to that is: The plane was a RENTAL... Do you really think FOB's use Exxon Elite on rentals? Bottom Line: There is NO correct answer. You do what makes YOU feel good and what fits your wallet. If this fellow had the money he would or have the plane fly.

"does venting the steam from the filler cap at the end of a flight make any sense? " it isn't likely going to have any effect. Odds are you'll be letting cooler air in that holds more water. ________________________________ From: lmassaro Sent: Sun, November 14, 2010 7:36:25 PM Subject: TeamGrumman-List: Re: Post Flight Question - Oil? I rarely fly less than 45 minutes at a clip for that very reason. Interesting side note... There is this old beater C152 tied down at my A/P. Never seen it fly, but have seen the owner get in multiple times, start it up, run it for 20 minutes at ~1500 RPM while its tied down. He thinks he's doing his engine good but in actuality is accelerating is ultimate death. Told him this but he didn't seem to pay much attention to us. So back to the original question...Given i fly long enough to get the oil hot (assuming 190 at the temp probe is >220 at the heads/etc.), does venting the steam from the filler cap at the end of a flight make any sense?

Neat airplanes those RVs and boy did we have fun ogling the experimental avionics like the new Dynon P/MFDs at AOPA Expo on Thursday.

The byproduct of combustion isn't just moisture, it's also acids, which will dissolve some of the metals that are vital for long engine life. The reason you want an extended engine run at temp is to boil off the acids that accumulate. > He circulates fresh oil through the engine which is better than > letting surfaces go dry. This is true. However, the oil drains in between engine runs, leaving the cam and cam followers exposed to the acidic environment. I'm no chemist, but the acidic environment may serve to remove the oil from the cam and cam followers which then leaves them open to rust. The rust .... even small amounts will wear the cam and follower .... and the engine efficiency goes down from there. A cam with no lobes ain't good. I'm not sure why, but when the cam followers deteriorate they get valleys etched in the face that look like filiform corrosion .... and they have sharp edges. Maybe someone else can enlighten us why that is!!! > He circulates fuel through the lines and carb which is good. Again, true. But 100LL doesn't have the varnish problems that mogas does ..... 100LL stays pretty volatile longer.

From: Anthony Dymond Thanks, this makes sense. Good reason to change the oil often. If you were putting a plane up for the winter would the procedure be to change the oil and run it just enough to circulate the oil? Doesn't water also get into the fuel through condensation? This is an issue, particularly in a boat where a fuel stabilizer is often used.
