Anyone know of any ways to do this?? So far, I've replaced 3 of them cause they get waterlogged during watercrossings.[addsig]

I have found that the chemicals in the RTV silicone actually messes them up also.[addsig]

Does somebody make a waterproof spray?

If I remeber correctly they make them for ignition wires so they dont get wet...[addsig]

I´ve used plumbers puddy, on some things I want to get back into on occasion. The same product used in refrigeration applications seems to work better (doesn´t get hard and sticks better) just have to make sure it´s free of oil and you don´t get the oil from your fingers in there.

My son came up with a good idea, I´ve used with success on some pieces. A simple small plastic bag with the bottom cut out, and two twist ties or cable ties. Maybe a dab of puddy or silicon where it ties. You can see if there is moisture in there and it can be removed quickly.

I´ve always been a little affraid sealing sprays will get in the same place the water does and cause problems.[addsig]

I do the bag trick also...seems to work for me, and when I'm done, I just remove the bag and toss it away, I use duct seal though. Rob

The problem isn't the connection, it that water actually gets INSIDE the TPS. I would try the bag trick, but then I would have to cover the entire throttle body. Its mounted right to it. I thought of smearing dielectric grease all over it. That way it wouldn't conduct a charge and would keep water out. I also found that sealing the distributor car and running a vent hose from the vent on it helps out.

I have two things that will help out with this...The first is a spray called Wire Dryer which works almost like wd-40 to help to displace water. The second is a silicone waterproofing spray for electrical components (I can't remember what it's called but I'll post another reply with the name) which is supposed to leave a waterproof cover over the components. I haven't tryed either one yet as I just got them but I've heard they work pretty good from my local 4wd shop.[addsig]
