Default Large baffle leak

The picture below is the baffle at the rear of the engine with the top motor mount protruding through it. I'm looking for an easy effective way to plug up/cover this huge pressure leak.

You can mold or buy a fiberglass cup which mounts to the baffles and covers the hole. Alternately, you can take a piece of baffle fabric and make a baffle to seal the opening.

If you are careful, you can seal it with RTV on the backside.

I just made some nice looking fiberglass covers for mine using 8 oz disposable food containers as plugs. The kind you get at the deli for stuff. Someone does make and sell them though.

Default Hole plugs

$40 for the set plus $15 fixed shipping from So Africa.

They will work on anyplane, not just RV-10?s.

I made my own out of fiberglass. Use a greek yogurt single serve container and clay to make the form.

A piece of aluminum or stainless steel tape will work just fine. Just pull off annually for inspection and reapply.

Default Engine Mount Covers

I hammered a pair of covers out of some 3003 half-hard sheet. Annealed twice during the work if I remember.
