Ideas on a Sealant or Gasket

LOL! Oh yeah, I should have mentioned that was a big concern for me when I first found the hood, then dropped to 5% concern after I saw how everything was arranged and then went to 0% after this test drive.

The air goes through the "hood duct", turns 90 degrees down into another duct, drops a few inches, turns 45 degrees into the bottom of the air box (which has a 1/2" drain hole in the bottom.) The air filter is then 2 or 3" above the top of that last "45 degree duct."

I had perfect conditions to see exactly what could happen: 45 minutes out on the turnpike while it was raining so hard that I had to vary my speed between 40 & 65 MPH for safety. Typical Oklahoma, it went from deluge to dry pavement as if pulling in to a garage and I was able to immediately pull over at a rest stop and check everything out. There was a little moisture in the bottom of the box but the filter was bone dry.

I would mask it off on either side of the offending gap & lay a bead of clear 100% silicone caulking in there. Then strike it down with a moist fingertip, pull the masking tape & carefully smooth it down, again with a moist finger tip.

But that's just me, I did carpentry for 20 yrs & that's how I roll...

If you do this, do it in a place where you are guaranteed a dust free environment for at least a few hours while the caulking sets up.

Another option would be clear acrylic latex caulking...it won't last as long, but is easier to remove if anything goes horribly wrong...
