Plenum Check - The Reason Why **ALL OWNERS PLEASE NOTE** - Page 12

johnnyb44 · 6th January 2014, 17:43

Thankyou both for putting my mind at rest. I've done the spyhole mod a few weeks back and as you say, it takes 2 mins to check to plenum drain making it so much less hasel of a job. . The previous owner has cut the tube as when I peer down the spyhole I can see straight through the drain tube at the road below. Next mod will be Jules filter to stop all the rubbish getting there in the first place
Many thanks
John

My plenum was clear under the ecu but still found water was pooling up on the drivers side as the drain under the servo was blocked. Maybe the car was parked at a slight angle but the water drains away from the plenum a lot better now that I have cleared the one under the brake servo. I would recommend doing it, I managed to do it from above.

Hi Ian.
now with added video jusy to show once the spy hole mod is in place how quick you can check the plenum and rod it, even more so with the bad weather we are having at the moment, Arctic

Hi buddy, thanks for the detailed advice and illustrations....fantastic for a an inexperienced DIY mechanic like me. Looking at the unblocking rod you used to push the build up of leaf litter twigs etc, it seems to me if the rod will push right through to the floor, is it a practical idea to try and get access from below with a hooked and thinner wire to pull any blockage down?
Thanks again and as soon as this rain stops I'll get right to it.

Best wishes for 2014

Yes easy to cut the bottom of both lower plenum tubes off from below.
Even easier on a ramp.

A job we do do on every 75 we MOT together with greasing all the metal brake pipes

Am so glad I checked my plennums today! Water a third of the way up the pollen filter and plennum drain blocked. Rodded it and the passenger side one too with a piece of garden cane. Both blocked. Have now fitted Jules' plennum mod. Just in time for a heavy shower. Thank God I did it today!
