It seemed like a good idea after paint to take the cowling off and start evaluating and correcting any baffle adjustments/leaks that need attention.
One of my known leaks is the cutout area around the inlet ramp that accommodates the prop governor.
I know from a loose oil plug on the engine case that this is essentially sucking air forward, back through and into the spinner area. A contributing factor could also be the cut out for the AC Compressor belt but that's a different issue that I have a path forward to resolve. I've tried to seal this with baffling material that I have around the governor itself but I've tried different shapes and sizes and it's just not sealing.
For those that have decided to just close it out, what has worked for people? Some ideas I have are;

For those that have decided to just close it out, what has worked for people? Some ideas I have are;
- Use scrap fiberglass and cut to size some close out pieces. My concern is there's no solid way I can think of to secure these since I won't have access to the back.
- Use new cloth, scarf the inlet ramps and drape the it over to cover the area. My concern here is having the 'walls' flat. I also can't reinforce the back at all with any flox fillets.
- My last idea is to tape out the 'walls' ensuring everything is nice and closed out. Cut a hole and use some fire resistant spray foam and fill up the voids.
- Same as above, but after it 'gasses out' cover it with new cloth and have the foam as reinforcement.
