Put on the back aluminum engine baffles. Some really large gaps around the two holes for the dynafocal/durometer mounts. Is there a recommended way to seal this area? By large gap I mean 1/4 to 3/4".
Thanks,

Hi Tom.....

We used red Hi-temp RTV on all the gaps, including those at the back. Also in the front, against the case, forcing all cooling air to go between the cylinders and to not let any escape. Three and a half years/ 450 hours later and it's all still in place.

Regards,
 
Looking closer, I realize that where the larger gap is goes right to the dynafocal mount which is mounted flush to the engine.

So, although there's a large gap at the entry hole through the baffle, it is effectively sealed off two inches later.

I'll be able to use either hi temp rtv or baffle seal but my concern isn't anywhere as big now.

Thanks,
tom
 
I use a bead of RTV alone for gaps up to about 1/4". Bigger holes than that I usually cut a piece of baffle seal to cover the gap and "glue" it in place with RTV - just uses less RTV.

The aluminum HVAC Tape works really well for this type of stuff and lasts forever. (Currently going on 5 years and 430 on my RV9A.
