I'm going to drain some oil out of my system, my AP put too much in, and when cold it shows 8.2 on the stick, too much oil also caused reading not correct and flow not right, so that will be my first fix

my ap says seating looks good, so i dont know what could go wrong

I have a question regarding my oil temperature. Since my oil temp had been running high (around 200-205°F), I recently replaced my Vernatherm a few days ago. However, during my first flight after the replacement, the oil temperature climbed to 225°F and was still rising, so I immediately returned to the airport. I wanted to ask what could cause a new Vernatherm to result in even higher oil temperatures. I also compared the new and old Vernatherm valves at the same temperature, and I noticed that the new one expands significantly more than the old one. I would appreciate your insights. Thanks! 1968 Mooney m20f, 201 cowl, overhauled oil cooler

Thank you, the fins is clear of rtv

nice panel btw! Do you mean the area I circled in red is needed some airflow?

Do you have similar setup? Any pics you can share with?

I’m little bit confused now, without the RTV on both sides, there are two big gaps in between, isn’t the high pressure air will just escape from the gaps and not flow through the oil cooler?

RTV there just to fill the gaps, it forces the air to flow through middle than escaping from the side

Actually yes, I think my oil turn black pretty quick. How should I fix things like stuck rings?

This picture (cruise)took from previous flight . All number are identical except the oil temperature (current) is around 205

That’s during climb, full cowl flaps open. 23c

I have a 1968 M20F with a modified J-model cowling and the cooler located at the back. When I first bought the plane, my oil temperature was stable around 195°F. A few months later, it started staying between 205-210°F during cruise. During this time, I switched from 15W50 to 100W Plus oil, overhauled the oil cooler, and replaced the rubber seals around it, but none of these made any difference. My CHT during cruise is normal, ranging between 360-370°F. I’m wondering if I should consider replacing the thermal valve?

Hi everyone I would like to install a surefly mag for my 1968 m20f based in KCNO is there any shop or experienced person that are recommended to do the installation? Any suggestions is appreciated
