Perhaps you've heard that the catch-can needs draining every few thousand miles (which solely depends on how much oil is blowing out of the breather)?
Probably this is what I heard. Makes more sense than oil change every few thousand miles  |

personally I'm out.
according to video egr improves mgg. I and others have seen a circa 10% increase in mpg following egr blanking. according to video the egr helps reduce thermal stress on engine yet if I interpreted it correctly it states egr is closed on max throttle which is when I would have assumed there would be max thermal stress? doesn't stack up to me but what do I know. for now I'll stick with the blank 
it might not be all good but I'm happy in the knowledge that I'm using less fuel so that has to have some benefits to the planet  |

The problem is that there is no printed evidence (that I know of) on the exact implication of removing the EGR.
I want to return to exactly how my defender left the factory so hence the decision to re-instate the EGR. I also would hate to be on the wrong end of some jerk from an insurance company trying to find any reason not to pay a claim should I have an accident and believe me they do. Is it legal to drive a modified vehicle which has had its emissions control features altered?? |

Probably not . It was put on to meet emission regs, so without it it will most likely not. 1983 Series 3 Pick up in Marine Blue

Wayne - agree bud. My jury is out re the EGR benefits (or not), but the Catch Can doesnt not seem to have a downside, just stops oil from the engine breather gunking up the inlet system... Years back my mates used to put the breather from the engine into a beer can strapped to the frame for the same reason... Defender "Puma" 2.4 110 County Utility (possibly the last of the 2.4's) |

Thanks to all on this thread, especially Blackwolf for the guidance in fitting. And Bob for selling me the ProVent.
I just completed mine:  Click image to enlarge The existing 19mm pipe from the top of the engine to the air intake system fitted perfectly with a "Reducer" as Blackwolf said. It just needed shortening by a few cm to fit bang on. The lower vent goes to the air system, and was a bit of a pain. I ended up using a 25mm to 19mm "reducer" elbow pipe with a 2nd 90 degree plastic elbow. The ProVent drains through the one-way valve into a little plastic shampoo bottle ("borrowed" from a hotel) below. I'll be watching for any oil residue. From my pic earlier in the thread, I'm definitely getting a bit of oil residue into the pipework - it'll be interesting to see how much it collects! I have one (still sealed) left-over "reducer" as per https://www.ebay.co.uk/itm/Provent-200-Red...Sw7CBdR4f9 I also have a spare LLN500030 (unused) if anyone wants one.

I'll take the hose, please Martin. This job is on my 'list of things to do' and that's the final piece of the puzzle. Let me know who you'd like paying.
I'm intrigued how you've ended up with a spare reducer? Darren 110 USW BUILD THREAD - EXPEDITION TRAILER - 200tdi 90 BUILD THREAD - SANKEY TRAILER - IG@landroveranorak "You came in that thing? You're braver than I thought!" - Princess Leia |

All yours, LRA... Where are you? can I drop it off on my travels? ZED - Provent Reducer reserved for you I didn't use the 2nd reducer, as I bought a 25mm - 19mm reducer hose (fitted better in my installation) for the lower port. Like https://www.ebay.co.uk/itm/90-Degree-Silic...2749.l2649 However the reducer I am selling is perfect for the top port as this attaches to the 19mm hose direct from the top of the engine.

Ah, cunning! I'll PM about the hose. Darren

I've been asked by PM for a bit more info on the ProVent install.
First...the mounting. If you have a look back on this thread at Blackwolf's pics, you will see he's created a bracket to bring the ProVent out into the engine bay a bit, away from the wing. About 5-6 cm away from the wing. I had to do the same. Basically there's not enough height between the wheelarch plastic liner, and the (closed) bonnet, so it has to be extended into the engine bay. Here's mine: Click image to enlarge Next easiest is the "feed" from the breather at the top of the engine. It just pulls off at the Air Filter end. Here's the next smart "find" from Blackwolf, the KAON reducer screws into the ProVent and changes the diameter of the ProVent vent from 25mm to 19mm. If you do that the existing pipe is a direct fit (once you shorten it and trim a few CM off the end). I tried to make sure the pipe was flowing downwards from the engine to the ProVent to make sure it doesn't get a block of sludge. Here: Click image to enlarge Linky to the KAON reducer: https://www.ebay.co.uk/itm/Provent-200-Red...4902.l9144 Next thing (Blackwolf has a very nice Nugget airbox, but if you have standard one). Taking the lower ProVent port back to the Air Box connector. This was really tight for me. I had expected to use the KAON again, but did not have enough room. So i bought a 25mm - 19mm angle elbow from ebay, and a plastic 19mm bend. Pics: Click image to enlarge and Click image to enlarge The 25mm - 19mm elbow (sadly they only have in blue) here: https://www.ebay.co.uk/itm/90-Degree-Silic...4902.l9144 The 90 degree bend here: https://www.ebay.co.uk/itm/Tefen-Nylon-Pip...2749.l2648 Finally, the drain. You can just see this on one of the pictures (2nd above), it's a half-inch pipe, through a one way valve. Mine just connects into a small shampoo bottle beside the wheelarch (careful as not to foul the steering column). Blackwolf explains that you need the one way valve because the system runs in negative (i.e. sucking) pressure, and will draw in unfiltered air without the valve. One way valve here: https://www.ebay.co.uk/itm/PROVENT-200-bre...SwaA5WjToh Also... lots of jubilee clips. My brackets are not the best (they are off a Suzuki GS850 pannier mounting system!). Seems OK so far, but I may improve the design in time...The ProVent is VERY close (about 2mm) from the brake master cylinder... Hope that helps!

to my mind this provent is definitely a benefit from standard, BUT I'M not convinced its as good or better than blanking the egr but please bear in mind that's from an un-educated fool.
