I don't know why it is that everyone (almost everyone) who installs baffles puts the #3 baffle on top of the #1 baffle. The short one holds the long one down.
It's too late to fix the left rear corner on this one without new baffles. It will always bleed air here.
Nose gear: so, the guy removing it says, "I know why it's so hard to remove, they forgot to cut it out to clear the thingy on the strut. There. Problem solved."

I would rather see a SPLIT Nose Pant - Like on the RV-6A. Front and back separate and you have total access to the nose wheel.

WRONG!
THE SHORT ONE HOLDS THE LONG ONE DOWN.
On the left side of the engine, the front (#2 cylinder baffle) is long. It goes UNDER the short rear (#4 cylinder) baffle.
On the right side of the engine, the front (#1 cylinder baffle) is short. It goes ON TOP of the long rear (#3 cylinder) baffle.

why? Oh, I see, so there is never an excuse to lubricate any of the rest of the moving parts.

I don't see how that is wrong?Think about it this way... As the air enters the top part of the engine... Baffled area.
It rushes in and is pushing OUT in all directions.
If the REAR baffle is on the INSIDE <--- As per your explanation. The air will PUSH out on the front baffle OPENING the gap/overlap and allowing air to escape.
Are you trying to say that the short baffle is STIFFER than the long baffle?
By a farts breath maybe - But you are putting the leading edge of the baffle into the air stream allowing that air to get under the leading edge and opening the gap/overlap.
BUT! By putting the front baffle INSIDE the rear baffle... The edge is now trailing in the air stream AND even the farts breath of stiffness becomes a sealed overlap.
This is using the SAME aerodynamics as should be used on the soft flexible baffling.

Barry,
It takes very little pressure to move the #3 baffle out if it's on the outside. Try it yourself. It isn't rocket science. There is no way "The air will PUSH out on the front baffle OPENING the gap/overlap and allowing air to escape. " if the #3 is on top.

Barry,
take a look at the pics I sent. THe #3 is hanging out. Why? because there bolt is on the bottom a long way from the baffle seal. Put it behind the #1 and the #1 holds it in place.

Gary:
I'm lost. You will have to explain your thought process / findings on this one.
Why does it take 'very little pressure' to move the #3 but the #1 is not affected?
Why doesn't the direction of flow effect how air will escape?
Since I am not currently working as a Rocket Scientist, how would you devise a method of proving your statement?
