P38A Thor engine....Air Con breather pipes.

Hi
I have read about the recurring problem of water spraying onto passengers feet(get a new car she said!) so was able to check it all out today. Located the passenger well rubber pipe which was patently seeking to burst its banks so I went underneath where I was expecting a pipe coming sown the side of the gearbox. The only thing I could see was a rubber valve way up by the tunnel that looked like a quartered heart valve. Gave this a good poke about with a long handled screw driver and hey presto was covered with blocked overflow. Very satisfying but apart from me, it covered a couple of electrical connectors. Is this the right fitting or should there be a pipe coming down below crankcase level?
Observations welcome!

Thats the end of the drain,there should be two of them one passenger side one driver's side.you only need to squeeze themand get an armfull of water and crap.shouldn't need poking.

Had to use the screwdriver as it is so high up and it was a tight squeeze under there(no ramp you see) and presumed the valve was stuck together. If that is the right fitting why is it above electrics?

When I've done mine I raise the suspension and use axle stands.slide your arm up between the body and bellhousing.works unless you have arms like Popeye.

The electrics you mean is the xyz switch. it shd either be a sealed unit or have a breather hole with a pipe to the engine bay - either way - design flaw, I agree.
I have heard of folks just cutting out one petal - then nowhere to get clogged, and it's pretty unlikely you'll get a blob of mud up there, unless you're a hard core off roader, or I suppose you can just jam a short length of tube in there

It's a one way valve for wading. Although it probably gets air locked up there anyway. I (just) got away with going above the recommended depth. Not intentionally, I might add. The river was running higher than expected one day. @Dopey really went for it once and got away with it. They're really quite well designed with little touches like that.

Dopeys one had a real good bath he had to hose out the mud i found the tide marks inside the car when working on it, i think he was trying for his submariners certificate

like the immortal scene from Risky business

BECM and car were fine. Dry as a bone. That's what rubber seals and grommets are for! And breathers and 1 way valves!

Mine was about the same depth. You were unlucky there. I did fond water in my airfilter afterwards do I only just got away with it. Air intake is behind the first wing skin so once water is above the wheelarch it gets hoovered up.

There is a maximum wade depth quoted in specs. Go over it at your peril.

My mistake, it was me that was lucky!

It was one of those point of no return things. If I'd stopped to reverse out I would have lost the bow-wave and the water pushing on that side of the car would have gone even higher up the wing and almost certainly blown it. I gambled on carrying on and got lucky.

Squeezed mine a few years ago but needed a poke also and yes an arm full of cold crap gushed out but sorted the problem. Hey ho what fun.
