Wow DC, after watching that I’ve been doing it all wrong. I never lean on the ground and my engine CHTs run low 300s. I’ll start running them higher and leaning on the ground.

Hello, for about a month now on the first start of the day with a cold engine, after a few minutes I get a vibration on my engine. Along with the vibration I get an EGT drop (90 degrees) on the number two cylinder. This lasts about five seconds and then goes back to normal. I have an IO360 A1A (500 SMOH) with Lycoming fuel injectors initially I thought it was an ignition problem, but when I tested my magneto‘s at 1000 RPM, the EGT’s would spike up on a single magneto. This is making me think it’s a fuel issue. I removed and cleaned the injector and it looked fine. I remove spark plugs and they as well look fin. When the engine is warm I have no issues. Mag drops or less than 50 at run-up. Any ideas?

Hello, I have a 64 M20E with the IO360. It has 400hrs SMOH and 18hrs since IRAN (New cam, lifters, bearings, cylinders were reconditioned with new rings). I have been running Aeroshell 80 SAE 40 mineral oil for break in. I have original instrument cluster and a JPI 700 engine monitor with oil temp. When I start the engine I get 75ish psi at 1000rpm on the oil pressure gauge. When I push it up to 1500rpm the oil goes pressure goes up to mid 80s. At 2300rpm on the ground it goes to mid 90s. I have confirmed the pressure with a calibrated shop gauge. The pressure is in the green while I taxi and at takeoff power. once I level off I notice that the pressure starts to come down. In cruise I see roughly 55psi indicated at 24 squared. My oil temp is in the 180s per analog and JPI 700 gauges. I know that the vernatherm should be operating around roughly 180 to allow oil to flow to the cooler. The cooler was overhauled in 2011 before I owned it. The pressure relief valve has 6 washers (9 max per IPC) under it. I added a 7th washer but was seeing 115psi cold at 1500rpm. I did not want to go any hiring with the rpm. I opted to take out the 7th washer. I am going to remove oil cooler and flush out and see if that helps. Does anyone have any ideas on why the pressure drops like that?

So no one knows of a silicone style set of baffles for the mooneys

Hello I was wondering if anyone knew of a kit to replace my doghouse baffling to a "traditional" silicone style baffling? I have a 64 M20E.
