    GUNK in the TD5 inlet manifold.....

    Well yesterday I removed and blanked my egr.... now I've heard from other posters here about how dirty it is inside the manifold, but until I saw it myself, I just would never believed it. Considering the sludge buildup over time I am puzzled how it isn't a scheduled service for the engine say at 100,000km, and how Land Rover have seemed to ignore it, knowing full well that it is there. I believe that with enough buildup over time and hot conditions to liquefy it a bit , it could find its way into the valves and cause a runaway. I carefully scraped out as much as I could with a long screwdriver and then wrapped it in absorbent rag (old towel) and continued cleaning and it never seemed to stop. Its a real pity as I had the head off a few months ago and should have thought of it then but didn't. If you haven't done your egr blanking and you've got a few km's on your td5 I would recommend a weekend in your shed and remove and clean the manifold.....there are procedures for this illustrated in the Pinnacles?.....I think....some one may point to it. I have heard of a few runaway td5's and this may well be a cause....food for thought. Anyway if I was you and haven't done the egr blank, I would be removing my manifold and cleaning it....I believe it is that necessary.

    Really? I've never heard of a runaway Td5.....then again I haven't been here that long
    It's pretty filthy in there, soon as my EGR blank arrives I get the fun job of pulling it off and cleaning it.
    I'm sure I've heard someone mention letting it soak in some sort of fluid....

    you don't need a kit if you're reasonably skilled and have a bit of gasket eliminator. even silastic will do.....

    I'd prefer to use a kit than risk bodging it myself, but that's because it's me
    I did google it.
    I found evidence of maybe.....4 or 5....
    Injector O-rings leaking diesel into the sump seems to be a candidate, or turbo failure.
    Not a particularly common occurrence it would seem.

    not sure if the sooty sludge will cause a runaway but it can't be good.

    Cleaned my manifold with a parts cleaner and pressure cleaner

    I used degreaser and a Gerni and got quite a bit out/all over me.
    Cleaning the EGR valve and butterfly seems to have made a difference in smoothness on teh expressway when easing off then on..

    I have a AGR delete kit but knowing my luck I am not going to try to fit it until I (a) have a full exhaust gasket kit and (b) have to work on the exhaust for something else as sure as night follows day a bolt will snap off in the exhaust manifold.LOL

    There are a few products on the market specifically for cleaning out your EGR valve and inlet section of engine.

    WYNNS DIESEL EGR CLEANER 150ml SPRAY - CLEANS AIR INTAKE FLOW SENSOR INLET VALVE on eBay!

    You pull off your intake hose and with engine running at roughly 2500rpm squirt in the entire can in short bursts. Last time I did it, I used 2 cans to do a good job of it

    My Ranger is overdue for a can. Most mechanics who use it seem to think it should be done every 20000km if not every service

    Did my EGR removal weekend before last. Could not believe how easy it was.

    My inlet was crappy but as mine has done 170,000 km, I reckon that the fuel pressure regulator will need doing soon, so I will remove inlet manifold to do this, and clean it

    I was asked " Is it ignorance or apathy?" I replied "I don't know and I don't care."

    I wonder how you do it without putting it through the turbo and MAF?

    I guess you could do it after the MAF and the engine would run in limp home but should you put stuff like that through the turbo, as it must be very corrosive to move the black gunk and carbon.
    My engine D2 Eu3 hardly runs with a hose off after the turbo.
