1.6 hdi air filter box mounting bushes

Post by PaulC5 »

Our 1.6 hdi Cactus started becoming noisy under the bonnet and I found the back of the air filter could be lifted about 1 inch so was banging about. Apparently this is common as the mounting rubber bushes wear through. This U-tube video shows what is involved in replacing the bushes, part no. 1623159380, £18 for the 4 bushes from a Peugeot dealer .

It was a pain though as I could not remove the small pipe top right that connects to the box cover nozzle so could only move the cover to one side (I always did this anyway when replacing the air filter) so the lower part of the filter box could not be extracted or moved enough to give much space. I managed to replace the front and left rear bushes (looking from the front) with a bit of washing up liquid so they slipped easier into their holes. To do the right rear one was not easy and would not go in its hole due to lack of hand space and I nearly dropped the bush down the back of the engine so in the end had to remove the pipe from the cover. Whilst doing this the nozzle on the cover broke off leaving it in the pipe. With the cover removed the lower box was easy to get out and then I found the bush could easily be slid sideways into its hole as there was a cut out which I wrongly thought was damage - if I had known this the cover and its pipe did not need fully removing. A right side wiring clip was also difficult to undo until I found sliding a small screwdriver down the back of it released its cover.

I managed to get the cover nozzle out of the pipe using force/pliers/a small screwdriver to lever out its side clips. Using Loctite All Plastics super glue I stuck the nozzle back and once set put silicone sealant on as well in case of air leaks. The pipe then clicked back in place and so far has been ok and not broken off. In the video you can see the cover nozzle is also broken off and this seems to be common as when looking at used filter boxes the connection is broken off on many. Used ones are around £60 but new from a dealer well over £200.

Got a set of these to fit on our Picasso - although since I actually put it back on its mountings rather than the 'somewhere near' it was left after the thermostat was replaced, it is much quieter!

It's a bit late now, but the pipe... viewtopic.php?t=90014

It's only the breather from the the turbo solenoid - on earlier cars it was just vented to atmosphere, not sure why it is on the air box, either to reduce any HC emissions, or perhaps to give a bit of vacuum to get it to close quicker. It probably doesn't matter if not connected, but you want to block off the hole in the air box lid so it doesn't suck dirty air in.

Good to know if it breaks off it is not important so I will not bother sourcing another filter box.

When I broke that little spigot on the filter casing I got bongs and an EML until it was fixed.

Did you go to the expense of another casing to fix it or did you stick the spigot back ?

I did a fix. I used a bit of old brake pipe and cut a thread on the outside. I cut a matching thread on the inside of the broken spigot and casing.

I didn't cut the thread in the plastic all the way so that there was a certain amount of tightening up as it was screwed back together. I was lucky that the broken edges matched almost exactly.

It's posted here somewhere.
