lower plenum drain

spent all day yesterday trying to fit a replacement lower plenum rubber drainage hose. .... what a nightmare. ...

looking from underneath the car it is very very difficult to spot. i eventually found it after threading in from the top, a bright coloured stick. it lives above and around the nearside lower arm rear bush and antiroll bar bush. what a pain to get access. !! simply put you cannot. you would need to remove lots of suspension parts to even think about going in there. i did manage however , to get one finger and thumb in there to pinch the end of the drainage nozzle, but no further. my original was split in the middle by some over zealous plenum rodding at some point by a previous owner or garage . the new replacement (second hand as no longer available ) was very difficult to fit after removing scuttle panels and pollen filter. so with only access from the top hole in the plenum, i managed to press out the old ripped one and seat the replacement part into its seat at the top. the bottom seal could not be made into the chamber, no matter how you tried with various pipes/tools. as long as the exit pipe sat 2 ins externally , it made no difference as drainage was still achieved. the upper seal in the plenum , i made sure that it was well seated and for strength, i used a strong adhesive to seal and stick it firmly into its grooves. the replacement has an arrow to indicate direction of fitting on the top seal. as it is cranked at an angle to the bottom seal and is very difficult to align. im glad its now done , but this job is a nightmare and even with 2 people it would be ... let alone on your own. ... never again , unless there is a tool to use to fit it , god knows how they did it in the factory ...
