Oil Catch Can for D4

I had thoughts of fitting a provent after the factory crank case vent filter in the 3.6 tdv8. The CCV filter vents to the suction side (like most turbo setups incl my turboed 4BD1) of the driver side turbo. But now the EGR is retired all that’s left is a film of oil. No soot. So pretty much lost interest in the idea.

I have a 2.7 2011 D4
i have read a number of post discussing the EGR and it seems those in the know have done something about theirs so I’m leaning towards the same.

Does my car just need the software patch or is that a hardware change as well?
Also, did you then take steps to clean the existing intake etc afterwards? If so, which areas should specifically should be cleaned

i have 130,000km onthe clock

You’ll need the blanking plate AND an ECU reflash to disable the EGR system. If you have a GAP IIDTool, you can buy the remap from Bell Auto Services in the UK and do it yourself.

I’d reckon giving the intake a good clean after blanking would be a sensible thing to do. Plenty of intake cleaning chemicals around.

Most people don’t bother fitting aftermarket ones on the Discovery engines.

Thanks for the response and I didn't know my 2012 SDV6 had one but if it is a pseudo catchcan, how does it drain or does it need to be manually done. Dalil in his earlier post said he fitted an after market one to his 2011 TDV6 and was amazed at how much oil was collected.

I had one fitted to my D4 for free with install of re-map and exhaust by Roo Systems. When checked to date, never anything in it. It is a very tight fit but is located on RHS top of the radiator, when looking from the front.
Can post picks if required.

Self drains back into the sump. The gasses are extracted back into the intake, with less oil than it began its journey, but it’s not perfect. The crank case is only one of the places that produce intake oil. The turbos are also a great source of intake oil.

Thanks Chappo if you have pics you can post or ping me, that would great. Interesting the can was empty. How long between checks and do you do mostly city or hwy driving. Do you know if Roo Systems had to pull off the inner guard to get to the pipes to fit it.

Thanks for the info....sitting on the fence now whether to do it or not but if I do will need to find a competent mechanic in Melbourne rather than having the dealer do it which they may not want to anyway.
