Slow day in the vintage Mooney world so here's another esoteric topic - moving cowl flaps - specifically they disappeared one plane before mine -SN 680002 - rolled off the line. I don't know if they ever came back on the C or if any other planes lack them. Can anyone enlighten us? Also, has anyon...

What kind of CHT, EGT's and Cruise speeds do yall get up at elevation? What RPM setting do you use? Mooney Zoom's with a tail wind and LOP - 8.6GPH SAD HEADWIND ------------...

Quick question vintage Mooney officianado's, I've put roughly 35 hours on my new to me 67 M20F since taking ownership and finally was able to download the EDM 700 data. The engine is a Lyc remanufactured IO-360-A1A installed in Feb of this year by prior owners. Normal cowl but it does have t...

Mooney M20F, Lycoming IO360-A1A I thought would put this out there for some advice & feedback. Recently I had my mechanic examine my engine and he mentioned pooling of oil and possible cylinder glazing. Cylinder glazing is a condition that occurs where oil film left on the bore "glazes" to a...

Hello all. Over the last 4 or 5 months, I have noticed my CHT's have been steadily rising and the spread from the hottest to the coolest is increasing as well. (Used to be 30 degrees, now it varies between 35 & 40) It is to the point where I can't fully close the cowl flaps. This hasn't been an issu...

Hi all, I am a proud new owner of a 1980 M20K 231. A bit more than I need, but I hope to grow into it. I have been reading this forum as a guest for a while and have just signed up to hopefully get some answers from some experienced and willing people. Keep in mind, I am very green. This is...

Oil pressure and CHT gauges (all stock) in my M20K are close to death and need to be swapped. I'm unable to find replacement parts by Googling. Could someone help me with the part numbers? Or even better, maybe one of you are getting a JPI upgrade and would like to sell me your old gauges? What...

I've had my 231 about six weeks and just took it for the first trip of any significance. My first question, what cylinder is the factory CHT probe on ? 1985, serial # 25-878, the normal LB engine. My #3 CHT temperature is limiting everything I do with the airplane and I'm wondering if the facto...

The original CHT sending unit for M20J IO-360 isn't working and I'd like to find a working one for replacement. Does anyone know what the cost and where to get a new one or have a used one for sale?

I've been on here quite a bit looking for a solution to the high CHT problem with my C. A related problem was leaning. Sometimes I couldn't get below 11 gph and EGT's were all over the place. CHT's were also all over the place with the front cylinders up to 60 degrees cooler than the rear, or specif...

Based on the related thread in "Modern Mooneys," I've been considering this topic but didn't want to muck up commentary on someone's big bore Continental with balanced injectors by blabbing on about my trusty but primitive carb'd Lycoming O-360. Specifically I've been musing about my EGTs and...

This is the opposite of the typical issue. Not even sure if I want to call it a problem. My '64 E has always run cool CHTs. This is not an indication problem, as I have had it this way with two analyzers and the factory indication. Now that we are living back in CT and doing winter flying I figu...

The analog CHT gauge in my M20J is reading well below (about 75 deg) what I see on my JPI engine monitor. Anyone know of a way to calibrate this instrument? The lead to the probe was shortened a little bit when the terminal at the end corroded, but it was probably a half inch, I can't imagine that...

What's a normal CHT spread for a 1990 201? I'm seeing: 1. 291 2. 329 3. 354 4. 340 Or to put it another way, the spread is pretty consistently 50-75 degrees with #1 seeming pretty cold. They never really get hot unless you really screw up the mixture. I've replaced all 4 sensors, and their EGTs ar...

I am looking for response from anyone flying a turbo or turbo-normalized aircraft. Most of the engines have a max manifold pressure based on continuous ROP max power settings. Have any of you experimented with trying to attain high horsepower numbers on the lean side of peak? I am assuming that runn...

I have read a lot of post on the forums that mention swapping fuel injectors to help with EGT and GAMI spreads. I have not seen an overview of the process from ground zero. As I have read some of the threads it seems as simple as swapping the high EGT injector with the low EGT injector. As I read...

I have a problem with the oil temp and CHT gauges. Oil temp sometimes works, sometimes doesn't. When I turn power on, both gauge needles dive to the left. When I disconnect the sender for the oil temp, it does the same thing. When I ground the sending units lead (off of the sending unit), it deflec...

My "J" is ready for its first annual since I bought it one year ago. My new mechanic refuses to sign it off because the original EGT has been replaced with a EI analyzer which he says is not a "primary" part. He wants me to replace it with the old original part. He also has an issue with the na...

Hello Forum, I just bought my first Mooney (a '68 M20F with J windshield, cowl closure, and other mods). What a great plane. But on the 15 hour flight back home, I noticed EGT readings I didn't understand. I was wondering if anyone on the forum had any thoughts on the issue. The plane has...

I've been messing around with running LOP and like the results as far as GPH (8.5 at 7-8k) and CHT temps ( -30 degrees) go. My question is regarding my EGT's. While running 100 degrees ROP the highest and lowest are on average only 10 degrees apart. LOP they are 80-90 degrees apart and overall abou...
