I was researching catch cans as I was considering fitting one to the 2.4 Puma. I e-mailed Mann-Hummel regarding their Provent2 unit. They advised me AGAINST fitting it as an after market installation. I know people do fit catch cans and I presume Mann-Hummel's reasoning against self installation will stand for all units not just their own. Here is the e-mail.

Thank you very much for your interest in our products
ProVent² is basically feasible for Diesel engines but it needs to be adjusted to the specific requirements of each engine type. Different parameters influence the performance and could, if applied wrong and not validated correctly, severe damage to your engine. Therefore we only supply this filter type directly to OEM´s and go through several development loops together with them. I am sorry to give you this negative feedback but in your case we are not able to support your inquiry.
Mit freundlichen Grüßen

So it is not just a matter of buying one, conjuring up the pipework and fixing it in place. Other factors need to be taken in to consideration. Seems to me that if factory fitted the ECU will be notified and the catch can integrated into the system 1982 88" 2.25 diesel

That reeks of corporate liability paranoia to me. I am sure that on engines with more sophisticated breathing systems there is likely to be scope for closer integration, but on something as rudimentary as the Defender engine there is no apparent engineering substance to that remark. If you fitted one incorrectly then undoubtedly you could cause damage (for example leaving it open to atmosphere), but then if you are stupid you shouldn't be modifying you vehicle in the first place.

On a positive note, not fitting one will save you around £200 and there are ways to spend that which are more fun than a catch can! Alternatively it could be the start of the new engine fund.

Having seen what mine collects and how much cleaner the induction system is since fitting it, I will certainly be fitting them to any future Defenders I may own.

1st service since fitting a Provent, I always remove the MAP to clean - normally covered in black gunk, not this time totally clean 👍 got to be better not having that stuff go thru 2.4TDCI 90 - everyday brilliance

S3 lightweight - 2nd car 24V fire risk with a full tilt and the windscreen down
S1 80" - first car fun - 75mph in neutral downhill once #wobblesallround

I do not have the Provent fitted so both my 2.4 Pumas are standard. The MAF sensor is always clean when I check it. 1982 88" 2.25 diesel

Minch90 did say MAP sensor not MAF sensor. The former gets gunked up, the latter doesn't, due to their locations.

lightning, IMHO with a higher mileage vehicle, it's not only the engine you have to be concerned with, it's the rest of the vehicle too, which has done the high mileage,..doors hinges seats, transmission bodywork etc etc. I'd be going for a low mileage unit every time, with a good owner/service history.

Sorry about that. Funnily enough it is never too bad. I clean it every so often with a bit of diesel on a piece of kitchen roll. I just put the twist of kitchen roll with a bit of diesel on it through the plastic sides and twist it about and whatever dirt is there comes off. 1982 88" 2.25 diesel

I have to disagree with that. In my opinion, you’re just paying a premium (almost double the price) for the mileage on the clock - to still have to replace components due to lack of use. I.e perished hoses, dried out bearings, cracked tyres etc. I’d rather the high mileage vehicle that will have had most the tired out items replaced. Saving half the money also lets you modify/customise the vehicle without any worry of devaluing it like you would a pristine, low mileage equivalent. 2008 2.4 110 Utility Station Wagon XS.

So what you're saying is, don't fit the catch can, save the money, ruin the engine, with saved money fit a M57? My kinda thinking. Especially fitting a M57 for £200. Where do I sign up? Whistle Laughing Monsieur Le Grenadier

I did say "start" of the engine fund! With interest rates as they are, your £200 could have increased to about £211.03 after ten years you need the new motor. Rolling with laughter

Rolling with laughter and then after 10 years, you will realize that your £211.03 will only buy you half of a decent catch can in the event that you change your mind Rolling with laughter because IC engines will be obsolete. New 2.4s are already difficult to source. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Indeed they are, which is rather disturbing when you have one with more than a quarter of a million miles on the clock. Sad
