Kicking off another post on how to install baffle seals from Gee-Bee. This time on a 252 / TSIO-360MB engine: Anyone have pictures of their original factory seals or a proper Gee-Bee install? I hear part drawings from Mooney are non-existent, however I'll try inquire with the factory this week. I'll also take good pictures of my install and post it here when I finish for future reference. Here's the starting condition...which has been verified to leak badly at the top and left side (Seal folds back in flight even when properly positioned at cowling install). AND here's the puzzle we need to solve

@Encore Driver, I have the same problem on a new “rebuilt” motor from globe so hoping it’s a setup/adjustment issue. Mine creeps open about 1/3 on its own unless I leave it in the closed position so the motor holds it against the closed switch.

Hi everyone, just joined, currently shopping for my first Mooney, and am looking at the M20K. Did not find a consolidated discussion on this topic via the search, so kicking one off. A few questions to start: I see the 231 has to be flown more carefully given it lack many of the 252 upgrades. What are the most important unique considerations relative to a 252? What are the must have upgrades on a 231? What are nice to have extras? Is the speed difference between the two noticeable? What is the bigest driver to making the 252 faster given similar HP? Any recurring ADs to watch for on either/both aircraft? What are the biggest problem areas to ask about beyond fuel tank re-seal, Turbo/Cylinders/CHT management? Thanks! Jay
