M20K 252 Baffle Seal Install

[Jay Aranha]

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

Here are some ideas: https://n252q.com/baffled-about-baffling/

One trick I learned is after drilling out the rivets of the old pieces of baffling. Lay the old baffling on top of the new one, and use it as a template to punch your rivet holes. 
I punched the first hole, then put a rivet in the two baffling pieces before punching the next hole. This keeps the two perfectly aligned all the way down the line.  My pieces fit perfectly.

@Jay Aranha any update to the baffle seal replacement?
