Another thread, but this time on how to change your oil breather. If your like me and get worried about how your engines running, then this is a must.
Before we start i need to say:
*****I have performed the maintainace myself and i am comfortable with my ability to do so and i can not be held responsible if you damage your vehicle in an event to follow my guide.*****
OK lets start:
I bought the replacement filter for £28 from my local dealership or you could get it from BM Mini Parts (www.bmminiparts.com - Home), part no.:7793163.
Take the oil cap off and place some where safe.
At the front of the engine you will see an air duct,
The front part is held down by 2 plastic rivet pins, with some pliers or removal tool, pull them out:
Now take out the holding clips:
There is a 5mm hex bolt in the middle that needs to be unscrewed:
Once unscrewed, pull the duct away from the engine:
The duct should be free and the engine should be like this:
Disconnect the battery connector which is on the left hand side on the right wheel housing:
It will be a 16mm hex nut for the bigger cable and 10mm hex nut for the smaller cable:
Pull the wires out and make sure they are free and not touching metal as it is still connected to the battery
The wires are clipped the wheel housing which need to be unclip the first:
Then on the pollen filter housing there will be 2 more for a pipe:
Get a small flat head screw driver and prise it to one side and it should come loose:
Once you have unclipped them, pull the pipe out of the clips:
You will now need to pull the wires off the housing which are held on by another 2 clips:
Pull them upwards and they will come loose:
Take the wires and lean them on the right hand side of the engine.
You will need to take the pollen filter out (can be replaced when you rebuild the car), which is located infront of the windscreen:
There are three clips, one on each side and one on the front,
turn them and they should pop up and they have springs supporting them.
Lift the panel up:
You will need to take the panel out, so be careful and pull from one side and it will come out. Once out, take the old filter out:
where the filter was, you will see 4 T30 (Torx30) screws holding another panel in place:
Unscrew the 4 screws which are Torx 30:
Once you have done that, you can now take the panel out. Lift the panel first and pull from centre:
We now need to remove the middle cover, which is held down by 4 5mm bolts, 3 are visible and 1 is on the side where the air duct pipe was:
Once taken out, lift the cover from the left side and take the cover off carefully:
Now for the air filter cover. there is a little cap that needs to be taken off, use a small flat head screwdriver to prise it out, but be careful as they are flimsy:
There are 5 bolts holding the cover on, 2 at the front, 1 in the middle (which the cap was covering) and 2 at the back of the cover. The front and middle screws are visible and are easy to get to but be care with the 2 at the rear:
The rachet is in the top rear olt and you can just make out the lower rear on the left. Be really careful as if you drop these, they're gone.
Once you've taken the bolts out, lift the air filter cover off and take it out:
Next to the air filter you will see the breather cover:
The cover is held down by by 4 5mm hex-head bolts, unscrew them:
You will now need to unscrew the wiring rail for the injectors, which are 3 T4 bolts:
Whe you are uncscrewing them or putting them back, be carelful as they can snap easily.
Carefully lift the rail and take the cover off:
This is how mine looked:
There is a holding clip, give it a tug and it will come off:
Get a cloth or a rag and pull the old filter off:
Give it a wipe down and put the new filter in, make sure you put the rubber seal in as well. (Sorry got no pics of the rubber seal)
Put the holding clip back on:
And now its ready to go back in:
On the engine, you need to replace 2 seals, they will have little tabs on them which you can see and use to take them out:
New seals on the left, old on the right:
Before i put the new seals in, i gave the holder a wipe down to get rid of any excess oil:
In with the new seals:
And slowly and carefully put the new breather and cover on:
Screw the 4 bolts back in and reverse the guide to get the engine back to normal.
thanks for looking
