strange BX oil filter

tim · Post by **tim** » Sat Oct 09, 2010 6:22 pm

Found an oddity I hope you experts can shed some light on. I ordered a filter for the BX19 TXD, and while working on the wagon the mk 1 eyeball told me that the existing filter looked wider than what I'd been sold. I shrugged off the idea as a trick of the light or lack of alcohol, but next day the idea persisted so out came the calipers and sho'nuff, the filter was just over 85mm, number 066 as I recall (it's dark and I ain't going out there again). The stock item is just over 75mm. The filter in question came on AEP's list as a Renault item. So what has happened? I assume the housing would have been changed as well or this filter couldn't fit. What would be the purpose of such a mod?
The hydraulic saga is nearly over and I'll post something once the MOT is my sweaty palm.......

have a look at this link you might be able to check deatails,

all BX's use the same oil filter except the early 1.4,

but some makes might differ in external dimensions, which as long as it fits in the space and the sealing surface and thread are correct i would not worry,

I can check the thread size on my (OE Purflux) filters if that helps?

There aren't actually all that many filter thread sizes and mounting sizes, so it's not surprising that some non-standard filters will fit. The difficulty is knowing whether the internal structure is right for the car – surface area of the filter, and the pressure relief valve in particular. If they are suitable, then so long as it fits, all well and good – 2CV filters are also correct for Ducati engines, IIRC...!

Changed the filter this p.m., and the housing seemed standard, in any event the 'correct' filter spun on OK and didn't leak so job done. Thanks chaps.

Sorry to exhume such a long-buried post, but I picked up a couple of NOS oil filters from a mate the other day, one of which was the same as I've always fitted to my BXs, a Purflux LS187B, as listed for the BX by Purflux. The other was a genuine Citroen one, marked as suitable for BX and a long list of others. That was a Purflux LS468A. Same mounting but bigger body, as in Tim's original post. Looked it up in a mid-nineties Purflux catalogue and that was the original fitment for al BXs except early 14s (as well as early Xantias). The smaller LS187B fitment has presumably replaced it over the years.
The Purflux catalogue also yielded a load of cross-references for the original type filter from other manufacturers – if anyone's interested I'll post them up. Might come in handy if looking at Eflog or at an autojumble!

That would be interesting.
I wonder how it would affect a BX owner who had one of the current smaller style oil filter if his or her car which was of concours standard and being entered in a competition?
I suppose its a silly question and i dont have nor ever will have a car of such standard but just a thought.

I wouldn't have thought a concours judge would know whether the correct filter was fitted or not, just how clean whichever one was on the car at the time of judging

It's not supposed to be just cleaning and polishing though!

Wikipedia wrote:Numerous local organizations sponsor 'Concours' events; traditionally vehicle judging at a Concours d'Elegance is much more demanding than that of a neighborhood or general automobile show. Trained judges examine the vehicle thoroughly and in its entirety. They rate each and every component. Only those vehicles that are judged perfect (or very nearly so) in every way, are considered eligible for trophy class.

Often the competitiveness of a Concours d'Elegance forces restoration of a vehicle to surpass 'mint' condition. Mint condition would be the state of the vehicle when it originally left the factory. Concours-quality cars often are given upholstery, paint, plating, and mechanical restoration to a standard far exceeding that of the car when it was new.

Concours d'Elegance competitions also are run for classic cars. Here, the emphasis is as much on originality as the condition, although this also is very important. The general aim is to present a vehicle that is in the same, or better, condition than it was in when it left the production line. Unless original, modifications are not allowed, and components must be suitable for the year and model of the automobile. Even components or features fitted to automobiles of the same type, but in a different production year or trim level, are not allowed. Original-equipment-accessories from the manufacturers own range are allowed and some competitions allow after-market equipment and accessories, provided they are of the correct period. On top of this, automobiles must be presented in flawless visual condition, as with other Concours-grade cars.

My grandad used to enter his motorbikes in VMCC concours competitions - that is until he was marked down on a bike because he had (correctly) painted the tank instead of plating it. He decided to concentrate on using them instead and ended up having a lot more fun!
