patch1 Posted September 22, 2008 Share Posted September 22, 2008 I think it leaks out from the turbo. As I understand it its the boost pressure the turbo creates that holds the oil back on these as I dont think they have oil seals in. I just wash mine out with petrol every now ond then; then stick it back on. Mark Quote Link to comment Share on other sites More sharing options...

JimAttrill Posted September 23, 2008 Share Posted September 23, 2008 We had a Defender 300Tdi with a power problem. Ok, it did have 600 000 kms on it, but the engine and turbo had done only about half that. I noticed when I test drove it that as I lifted off to change gear there was a big puff of black smoke out of the exhaust. We took out the intercooler and found it just about blocked with burnt on oil deposits. It took quite a bit of cleaning including soaking in engine cleaner for the weekend. After that it went just fine. What was happening was that the turbo pressurises the system, and when I lifted off, the pressure in the system could not release quickly. This caused the injector pump to think that the turbo was still boosting, so it would overfuel momentarily until the pressure dropped, causing the puff of black smoke.

I put a straight through exhaust on it, blanked off the ERG and i have just had a upgraded drop in intercooler delivered from Brunnel Performance. I will let you know if there are any further improvements but the exhaust mod made a vast difference so the CAT must have been clogged up. Does any one know if the intercooler can be fitted without taking the fan out ? Thanks Andy Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted September 23, 2008 Share Posted September 23, 2008 you may find it's a build up of oil from the breather my last disco had it and my TD90 used to get it in the air fillter if i were you next time it's running take the breather pipe off see how much blow buy there is if there quite a bit i'd think thats were its come from.
