I have two air intakes bolted to the grill of my "new" 2006 Voyage 33-V that feed into 3 to 4 inch round corrugated ducts. I noticed the hoses are sagging down below the bumper and found the sag is due to water in the ducts.

So I have two questions:

Are these engine or heat/AC ducts?
Is this water from condensate and/or the road during rain or do I have a real problem?

Many thanks for any thoughts you can share.

THey are neither engine heat nor A/C ducts. they are engine COOL ducts

They counduct air over the spark plug wires to improve cooling it is the fix Workhorse came up with to fix a problem caused by body builders not letting the outside of the engine breath properly. (not enough front grill, too small of a dog house) For some reason.. i do not need those.

You may drain the water by any means you like, a quarter inch hole would be my recommendation. or perhaps smaller.

Yeah, I'm surprised you need them on the Voyage - it's gonna be identical to my Sunrise and never had an issue. That is once I got decent plug wires on it. Keep the factory heat sheilds!

Our configuration is wide open on the sides into the front wheel wells - ventilation isn't an issue. It's common for the 8.1 to burn plug wires due to them routing right next to the exhaust manifold.

And yes, likely water from driving in the rain.

Drilling drain holes is a great idea.

Thanks to both of you. I'll be at the RV shed tomorrow with my trusty cordless.

DON: I suggest you look to see if the "sagging" may have caused the discharge end of the ventilation "tubes" to be misplaced or poorly aimed. Their purpose was to discharge cool air into the spark plug area near the rear of the engine on each side.

Thanks for posting your issue, because I've never thought to look-see if mine are holding water-but I can certainly see how that could happen. Ed
