Ford F53 Water injestation in the air intake

We have a 2001 Itasca Suncruiser with Ford F53 V10 gas engine.
There was a technical service bulletin for water injestation into the air intake. At times, during heavy rains while driving, the air intake would suck in water, drowning the air filter and causing the engine to stall or lose power. The fix for this from Ford (since parts are no longer available for the fix) was to use a dryer vent hose and reroute the air intake higher up inside the hood. I did this, but the problem continued. So, I brought it to the Ford F53 service center and they suggested that I raise the dryer vent hose even higher inside the hood, so we did that (raised to the maximum amount pointed the open end toward the rear). But still the problem continues. Water gets sucked in while driving. I am using the flexible aluminum dryer hose. Has anyone had this problem and what is the REAL fix for it (other than not driving during rain of course). ???
Does the Banks Cold Air Intake fix solve this problem??
  • A small amount if water ingestion is not a problem, but a large amount can cause catastrophic engine failure. Some intake systems allow water to pool in an area and then the engine gets a big slug when you go around a corner.

    If the area where it is pool is in FRONT of the mass air flow sensor, simply drill a hole in the low spot.

    It looks basically like this, except I used the metal dryer flexible vent hose.

    Where is the dryer vent hose pointing to or at? Have you tried pointing it back towards the fire wall behind the engine?

    YES, we expanded the metal dryer vent hose up and turned the opening facing the fire wall. We even have the dryer lid on the hose (with the flapper removed). This is pointing to the fire wall, not open toward the hood.

  • Banks intake will solve the problem. Plus, combine it with a free flowing muffler (which you're probably due for if you still have the original) and you'll gain a little more power too. Note: there's plenty off muffler options besides banks which work as well. I went with magnaflow last time around.
