Hi folks - just about reached the end of my patience today with trying to get the standard oil filter housing to seal properly - both filters (genuine and aftermarket) I have purchased have seals that don't seem to sit in the groove properly and then leak as the canister won't seat correctly. This afternoons efforts resulted in a large pool of fresh oil on the workshop floor as the seal seems to have pushed out somewhere around its circumference. So done with messing about - does any one have a recommended source for a spin on conversion kit - tried most of the usual places with their search functions but can't seem to find one unless I am being particularly useless (entirely possible). Any pointers gratefully received - it's a diesel Series 3 by the way.
Many thanks.....Ian

Have you told checked the no old seal left against the engine block?

Moorhouse2 · Apr 16, 2023

Hi there - its the ring seal that goes between the actual cylindrical filter canister and the housing I am am having trouble with rather than the seal between the block and the filter housing. Both seals just seem to want to twist as soon as the canister bolt is tightened (I'm being careful not to overtighten) and then subsequently leak. Probably a function of the rubbish quality of any rubber part I seem to buy for any vehicle these days.

I’ve found if you turn the body as you tighten it helps but no need to overtighten

but this will save all the oil up your sleeves

The one off a 2.5 NA also fits

Thems expensive. I’ve only ever had one leak on me and it was my fault for being too lazy to swap the seal. In fact I did one a couple of weeks ago and the crap houses sent me a britpart one.
Turners engineering do them but at those prices I’ll stick with the original.

Be vat and postage in that too.

I used a Rocky Mountain (?) one on my Lightweight 5 years ago. No problems & makes filter changes much easier. Also now uses same filter as my 200tdi Defender so no worries about ordering wrong one!

You probably just need to tighten it a bit more, get the housing to pop up into the groove.
And make sure you have removed all old seals from the groove.
And have a bucket underneath through removal and replacement, save on floor cleaning.
It is quite easy when you get the technique. I use Britpart filters, they are a couple of quid, whereas canisters are more expensive.

Thanks for the various suggestions above - much appreciated. As you say, it seems like quite an expensive fix although I guess its a one time cost - I found something in the US as well at about half the price but not sure if they ship here so waiting to hear back. In the meantime, I put the canister part on a true flat surface and there was a very slight unevenness to the rim so have rubbed that flat and waiting for a new rubber seal to arrive to see if that solves the problem. Has been like that since I got the vehicle so not sure why it chose this time to leak - we'll see. Thanks again......Ian

My brother bought one of those conversion kits for his 2.25 petrol and discovered there was not enough clearance between the complete assembly and the frame. This was because he had an oli cooler takeoff as part of the original assembly. Had to send it back.

Some Series supplied for military use in various territories had an oil cooler.
As you say, takeoffs for the pipes behind the oil filter adaptor, and the cooler itself was a finned pipe bent into several U bends, which fitted behind the grille and in front of the radiator.

Yes, my brother's 5 door 109 is supposed to be X Dutch military. Has " convoy lights" and a few other peculiarities.
