    Fuel transducer routing in an M20C

    Is that plastic string holding the firesleeve on? You get the purpose of firesleeve, right?

    M20J oil pressure anomaly

    Old wives tale. The regulator simply dumps excess oil above a certain pressure.
  3. The same reason a radial engine hydrolocks after a fuel stop. Theres no way to guarantee it wont, and it trashes the engine if it does.
  4. be sure to un-hydrolock the cylinders before starting it
  5. Its not the camshaft so much as the lifter faces. The cam is hardened steel, however the lifters are chilled cast iron. All the photos of these spalled engines, its always the spalled lifters running on a no-so-bad looking cam lobe. Often, the lifter is in the beginning stages of spalling while the cam lobe is still serviceable. A lot more about this is being written over on Beechtalk. They accept the fact that "fly it often" isnt enough, and even "pour camguard and dont worry" isnt enough either. Many pilots there will pull lifters for a pre-buy or after a fishy iron reading on the oil analysis. They often catch the beginning stages of lifter face spalling and are able to save the engine. Of course, our Lycoming engine lifters (except the -76 series) cannot be removed without splitting the case, so it doesnt help us. I did pull a couple lifters out of a IO-550 in a 2002 M20R while they had the cylinder off. Both showed early signs of failure. One has parallel scratching and the other had very slight pitting and worm trails. Cam was perfect. Its almost always the lifters first.
  6. The most important and most highly loaded parts are the lifter faces and cam lobes. No way to pre-oil them. only thing to do is fly it and hope for the best. A plug-in engine dehumidifier is worth the money. No water, no corrosion.
  7. K&W aviation at Laporte has been maintaining my Mooney and two others for the better part of 10 years. I’d recommend them.

    I haven’t been excited about a small piece of kit like this in a long time but this thing looks really coolI haven’t been excited about a small piece of kit like this in a long time but this thing looks really cool
  9. Is the engine on this airplane painted red, by chance?

    ILS vs LPV

    Let me be more clear. You don’t have enough gas to go missed and try again. You declare an emergency and you are going to land. How low does the LPV approach give guidance? That’s the question I have.

    ILS vs LPV

    let’s say the weather is right at 200 1/2 or maybe even a little bit lower and you are really running low on fuel. We know and ILS will give guidance all the way down to the runway for the most part. CAT 2 and 3 Approach certified facilities certainly will, and cat 1 facilities will provide guidance although it’s not really tested in that area. But still, the needles work...But are we sure that a LPV does the same thing ? In other words what do you do whenever you get to DA and the needles disappear on the LPV, what do you do then? Admittedly I haven’t tried to fly a GTN750 below DA but IIRC it suspends and gives a “missed approach point reached” message. IDK if the needles are removed from the Sandel I’m not advocating busting minimums anything like that. I’m just saying that if you’re really there running low on fuel and you really have to make it in and you may have to continue below MDA to the runway because it’s safer option than going around, are you sure that an LPV approach gives guidance below DA?

    When should I change the oil?

    I bet your next time will go much faster, not having to fix others shoddy workmanship

    When should I change the oil?

    I’m surprised it took your IA seven years to know that there’s one there.

    Mooney down in Paramus NJ

    I agree, keeping the water out is most important. But what do you do about water that did get in there. A line guy left the cap loose, or installed it in a cocked manner. Now the water is in there, and you sump it and sump it until its clear. What about the water that is still there, in the tank, you cant remove?

    im not sure what data says 100 hours on the oil is safe, but I dont think the oil goes poof at 54 hours. But it isnt logical to arbitrarily double something and assume its ok. A Piper Cherokee in the Utility category is rated to +4.4 G's, but you cant just say well its good to 8.8 G.
