You might of read about poor Boris in Mini Chat if not ill explain. When we changed his Oil and filter today Oil started Spurting out of his oil filter at the Bolt end under high pressure  this is a situation weve never encountered before so we rang our Gearbox Rebuilder who thinks it could be the little O ring that sits behind the Bolt so hes sending us some out  Are we the only ones this has ever happened to? If anybody here has ever experienced this before please share your experiences  Was it the O ring? Did it Cure it? And how do you get the Bolt completely out of the bowl to replace that O ring as ive never stripped it to its componants before   Any help would be very gratefully received Huggz Jodie |

Not on an auto, but yes on a Mk1 I used to own many moons ago  I think what happens is the rubber washer gets deformed and hardens over time. This means it's fine until you disturb it - then when you re-assemble everything......... Also the washer is actually more sort of 'top hat' shaped (maybe boater rather ) so careful insertion into the hole in the end of the cannister is a good idea, as is making sure all the old crud is removed and check for the edges of the cannister being distorted (this is what made the Mk1 leak) as some people do them up too tight to cure a leak. They should be tight enough to seal no more- ; no less Removing the bolt is a simply a matter of pulling it out, but claggy old rubber may be gripping it so give it a wiggle Emma |

Thanks Emma borris doesnt have n O ring like a top hat shape though Boris just has a little rubber ring somewhat like in appearance to the one of the dipstick,is this right or is there something missing? on the outside of the canister there is the Bolt head of coarse below that is a metal washer then below that between the bowl itself and that washer is a little rounded rubber O ring ? By the way did you get my PM? Huggz Jodie |

Nope...the manuals only show an 'O' ring thingy. To a degree that makes life simple as these are readily available in all sorts of sizes. I would suggest thatwhat is needed would a snug fit on the bolt, and fairly chunky in section.

Here we go....  To remove the bolt, you'll need to take the circlip off first. Then once you've picked it all up off the floor, clean it and re-assemble with a new O ring . The oil filters I have in stock (yes I have a stock of parts, sad aren't I?) some have new sealing washers in, it's fact like an ordinary washer but made of rubber type stuff. Don't forget to put the great big o ring back in the filter housing once you have pulled the old one out (unless you've already done that of course) Emma |

Right lets go through the numbers as they appear left to right 1 Unipart GFE 479 got one of those 2 circlip got on of those(so thats why the bolt wont come fully out) 8 deffo got one of those 7&3 not sure but i assume they are lurking behind the plate(8)? 6 i must have the spring cuz if you push the filter against that plate it springs back kinda thang 4 thats the little blighter causing me my problems methinks? 5 deffo have one of those its holding the rest of the thing together just before the bolt head theres like a cup washer its not numbered there but shown butted up to the bolt head,i have one of those too but mine moves its over the bolt shaft but not fixed,its kind of trapped between the Filter bowl and Bolthead is that right? and the side that sits against the filter bowl is kind of hollowed out that side so it fits over that Leaky O ring. Yup i changed the large O ring thats supplied with the Filter and no your not sad for keeping a stock though all the ones ive had only have the big sealing O ring that fits betwen the filter Bowl and filter housing "some have new sealing washers in, it's fact like an ordinary washer but made of rubber type stuff" where do they go? are they in the piccy?

*phew* I'm glad I'm not sad ....The rubber washer is part 7 Yes you are perfectly correct in saying the cup shaped washer sits over the O ring. Perhaps it has worn? It's the only thing keeping the O ring in the corrct place. A thought that has just struck me, is the bolt/cup/O rin properly centered (in the right place - ie over the centre of ) on the end of the cannister? I'll have a play with some I have here tomorrow - see what's what  Emma |

I think they are all centred in the right place? The canister has a indent in it that the cup washer/bolt sits in And the O ring im guessing well as it sits around the bolt it would be hard for it not to be seated correctly? If i were to get another O ring that sits tight around the bolt but is bigger and thicker when done up tight shouldnt it seal itself? Im guessing thats what Martin was saying his are now a little larger im guessing so they seal better? wow this threads getting long  all for a little bit of Rubber ;D |

"wow this threads getting long all for a little bit of Rubber ;D " *sniggers* long ones are better ................................ threads that is Yes a new fatter O ring should cure the problem. The reason for me experimenting is simply to check out a few ideas that may shed more light ......that's all Emma (invetrate investigator of pointless things) |

were not 100% certain its the O ring its worrying because if theres a problem with the filter bowl where on earth do you get a replacement from thesedays? Just hoping its the O ring Fingers Crossed |

I've had this exact same problem recently when i did an oil change and my problem was over tightening of the bolt which then distorts the bowl and the trouble is it never gets tight. When i read the haynes manuel it says do it up finger tight (erm yeah right) but it's kinda right basically it's a bit of trial and error! just look at the bowl end and the housing and when the two meet do it up a little more then give it a try (less is more in this instance) and tighten slightly if needed but never over tighten because you cannot buy these bowls anymore, i tried everywhere and got told (and sometimes laughed at) that i had no hope. luckily i found a good second hand one to replace mine because i proper mashed my bowl bell end ;D up through over tightening, but i did fix it while i was on the search for a replacement by using a sealing washer (number 7 in above diagram) underneath the o ring then re-tightened it and it worked  i managed to get 1,4,7 and 8 (in above diagram) from mini spares and now with the new (second hand) bowl it's as good as new. If you have to buy a second hand bowl make sure it's in good condition with what i can only describe as a nipple at the end where the bolt goes in as this is what pushes against the o ring to create a seal and once this is over tightened this is the first thing to go. |

Methinks it's time for me to invent a cannister modification Emma |

not really the replacement i got never had the circlip either Could be wrong but i think the only reason its there is to stop all the bits falling out when doing a filter change The pressure plate,spring,and metal and rubber washers cannot go anywhere once the bowls on its just when its removed that all the bits fall onto the floor but you soon learn the order they go on in and so long as you don't loose any buts just pop them back on,though the circlip is handy if you can get one but not essential |
