Did modify the plenum air vent covers by adding a layer of finer mesh to the underside to stop natures split pins (pine needles) from entering, and coarse foam (fish pond filter grade) made to fit the open drivers side. I wish they'd put the ecu's in the battery box and the battery in the boot like my old P6 V8 ....

Oh yes servo one can still block up clean and cut some off it 15mm

With the bad weather coming back with a vengence rain then snow and cold frosts check those plenums as water can freeze and cause a plug in the lower plenum and if it rains right after a cold spell they can fill up quickly ad we all know the outcome better to be safe than sorry Arctic.

Maybe only applicable to cars laid up Steve
The heat from the engine soon thaws the bulkhead through

Hi Jules noted i was thinking more of if the tube had a bit of debris in it and the flaps have not been cut off and the the tube being at the lowest point could still be frozen its like the Arctic here

Jacked car up today & cleaned out the plenum under the servo, it was totally blocked, also got all the muck out from around the servo & placed some mesh to stop leaves etc getting in again, thanks Artic for the thread info & photos, great help.
Thanks to you guys I'm getting to know this car slowly but surely, next jobs are PCV filter & air filter, cheers John.

So glad I read this, popped out to take a quick look tonight, and about 3" of water in there, sucked out with a hose for now, will get on with sorting that after work tomorrow . Thanks again probably saved me from a big issue, have ordered new pollen filter, luckily no sign of water inside the car, looks like I have gotten away with it.

Ahhh Chris but you have not solved the blocked pleum as it need to be rodded to get the muck out of the plenum tube if it pours downs agin which it will no doubt it will start to fill up again rod tomorrow as soon as you can be on the safe side

Well it is that time of year when we need to check the plenums at least once a week rain wind then sunny spells all amounts to blocked plenums due to the dust and rain mixing making sludge in the plenum chamber, so please check the weekend if you have a minute which is all it takes if you have the spyhole mod cheers Arctic.
