Maybe these could work but lack flexiblity and the bonnet may well get in the way still opt for the 10mm or 15mm plumbers pipe spring £3.50 from any good DIY shop Arctic.

And once you've cleaned the lower drains out why not stop all the debris going down there in the first place.
We all know how to do that don't we?

And it's not a plug to buy my plenum guard leaf shield BTW (whatever you want to call it !)
There's netting and sponge you can source yourselves.

Then stop worrying about drains and just check them on the annual service.
Put some water down the RH bonnet hinge area every time you wash the car, see it coming out below, you know they are clear ............done and dusted !

Checking them every week is a little paranoid me thinks

I was surprised after cleaning all the muck out of mine and flushing through with a hose pipe that the driver's side drain under the servo was blocked as noticed it when under the car and cleaned it out with a long screwdriver ... not sure if it's good for the complexion, but certainly got a face full of rotting muck and water just from what was in the tube ! lol.
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

Some early cars had a low partition between the two sides, so it was essential to ensure both drains worked well. Later ones could at least drain via one of the two, but obviously not good relying on one being clear.

I am confused.
I have a 03 plate MG - so do I just have 2 plenums drains to check (driver + passenger side) under scuttle guard?

Is this another mod?
Is the plenum guard same as Jules scuttle guard?

And even more important this time of year with the Autum leaf fall etc.


Yesterday a member of the club Mike came to have his handbrake mod fitted, as i always do i checked the plenum's after asking if he had checked them it turned out he had only brought the car Sunday so the car was very new to him, he had looked at the plenums from the drivers side and could see some water and he also heard the sloshing sound when driving.

The results can be seen below so come on gents lets keep on top of these plenums do the spyhole mod and its only takes 2 minutes to check for water once applied.

Pic 1 water at least 3" deep

Below is how to do the spyhole mod you will need a rule pencil 25mm drill bit and a 25mm rubber bung Fig 1

With the scuttle shield panel removed measure 97mm and 180mm from the points in the photo below Fig 2/3

Here you can see my template which i use at meets so i can easly turn over a good volume of trays in a few minutes Fig 4

With the panel marked out and your drill ready with its 25mm bit we/you can now drill the spyhole Fig 5

When you drill the scuttle tray makes sure you have support under the tray at all times Fig 6

Once drilled trim the hole to make it neat for the rubber bung to fit nice Fig 11

If you intend to use the plumbers spring look for a 10mm or 15mm a boot lace and a tube mine was from an old wendy house but any 15mm tube will do 12" to 15" long Fig 15

Also grind or file the end of the spring to remove the curl so it is smooth and will easly go into the tube Fig 16

Hope this helps the new members and remember check the plenums regular Arctic.

Excellent Steve - I will need to get one of those plumber springs
