Note to DriVer or 007 and all Rain Experts

[tvp]

Hey on another note : Still with all the modifications : Newmar new air intake , new plug wires and Workhorse fresh air kit,
and Bulb Weather Striping


Still when it rains heavy...after about 30 min driving in rain ....engine misses on load,

Stops Rainning and 1/2 hr later runs great ??

Could water be spraying off tires on Plug wires or ??

take a close look at the wheel well mounted filter box. ANY small open seam will allow wet air to get sucked in.

tvp... I had the same problem with the engine missing on load when the road was very wet, with or without it raining. This was on my previous 2001 P32 chassis with the 8.1 engine. I checked it once and the whole right side of the engine, including the coils, plug wires, etc. were soaking wet. This problem happened almost everytime the road was wet .

I devised a heavy rubber like plastic deflector and mounted it on the very short metal deflector Workhorse had along the right side. After this install I no longer noticed the problem.

Take it for what its worth but it worked for me.

As ED Gray has said 04-06 air filter boxes have very loose fitting tube and box seams, some people have been able to put a credit card thru seam of box, so when you draw in alot of wet air under load, in comes the water to senser.
I have a 02 chassis everything is tight into my box, plus my spark plug cables are wide open to any water from wheels driving in rain, I have had no skipping with this. In fact have not had any trouble driving in rain with the weather strip install since I put it in, in 04, I will still leave it in because it protects the windshield motor and plug from rain water.
I'am going to put this to rest because I have purchased the new air-intake system from BRAZELS. It removes the TUBA allowing more air to pass thru the radiator and it is more efficient allowing more air into engine. There is a post on the new system and a install on DriVers coach with pictures, its a DYI install. "007"

tvp - From an earlier post, you can see that the factory airbox on my coach was open on one side enough to allow water to enter the intake system after the filer.

I replaced the factory intake with a cold air intake and "fixed" my problem. We have had a lot of rain in S. Indiana this week and I can atest to my "fix". No problems in driving rain.

[Bob (WA0MQE)]

Drivers correct regarding actions taken. I considered the air flow also when installing the deflector. Although I believe the deflector actually helped with better air flow over the right side of the engine just to be on the safe side I also installed a homebrew "Engine Ventilation Cooling Kit". This was back in 2002.

But as we're all are aware of different manufacturer's have caused their own set of problems due to different designs.

Good point , WaOmqe....we must watch all the modifications we make that it does not cause other problems,....seems like the manufacture can do this on there own......lol
