Plenum Drains - Pollen filter ECU ?
 

Hi all,

So I spotted the car was misted up, tell tale sign there must be some water inside, I hoped I had left a window slightly open.
Turned out the drivers plenum chamber was blocked.


Cleaned out the plenums, a bit different on the V8 it seems. No rubber tubes, instead a small diameter metal tube, sadly easily blocked on the drivers side - dammit - so I have a little water to dry out from the carpet.


Under the windscreen scuttles, I of course found the pollen filter, which I will also replace, but where is the ECU for these V8's? On the other Rovers/MG the ECU is in the same chamber as the pollen filter :shrug:



Any one done any sort of mod for the plenum chambers, especially the drivers side, since the drain tube is so small, thinking of doing the Jules type mod to stop debris from getting into the chamber, but what about drilling a bigger diameter hole - treat the newly cut metal and put in a wiring grommet.
Any thoughts one and all.
Cheers

The ECU is behind the glovebox, the best way of ensuring a clean plenum is to clean and dry it all out then fit fish tank pump filter foam in each side of the plenum, this will keep debris out while allowing water to pass through.

Hi Andy many thanks mate, since I have to do the sunroof mod on the saloon, when I dismantle the passenger side to get access I would have spotted it and probably wondered what the heck it was :)
I will get some of that foam, cheers.
Perhaps fitting a bilge pump would be a permanent solution haha
Although the drain tube on the drivers side is under the Servo, it is pretty easy to get to from the engine bay.
My real concern was the small size of the metal tube.

I have never bothered to clear the drain under the servo, as long as the passenger side one is clear the water finds its way out.
