I’m sure people will tell me if I’m wrong but doesn’t most of the oil/crap come from the breather pipe feeding into the air intake.
So taking off the EGR will stop some of the crap out. But the EGR only operates at low speed/idle as I understand it.
If you wish to keep the air intake system “CLEAN” and cool you also need to remove breather pipe.
Or you’ll need to do this regularly.
The breather oil itself simply washes through, but when mixed with the carbon from the EGR creates a very sticky black paste that keeps building up.Quote:

To try to deal with this I built an oil separater between the air breather outlet and the intake before the Turbo. My next step would be to fit a Proventor.
Dishwasher would be fine i guess but how would you clean the ports though?
The reason for giving caution in cleaning is there are gasket and other surfaces that could be damaged If care is not taken .

I had a mate that used a dishwasher to clean his alloy motorbike parts.:D
That dishwasher is now in his garage, his wife came home and found the parts, made him go out that day and buy a new dishwasher.
Must look at the oil in the manifold as I received my EGR kit today, had to clean the loom today so a new on of them is also on the cards:(

Porgey, what did the oil separator look like ? Do you have any pictures that you are able to upload to this site that will give me an idea ? Yes, when inspecting the air intake pipe from the aircleaner box to the turbo the other day, I was concerned at the 'grundge' on the inside of the rubber pipe. I think I should at least make an effort to clean this.
Funny you should ask. I was looking under the bonnet of jf1056's Td5 Disco and he has an oil separator. He said it was $60 from Supercheap.
I cleaned my manifold the other day.. no probs.. degreaaser gets it off. The main problem was cleaning me... took hours, 1 bar of solvol and a full tank of hot water.... and i still kept finding black spots a week later....:):)
I remember this well, and being tight on solvents, I held it up in front of me and hit it with the high pressure water washer first and then solvent to finish the job. All was going well until most of it came back on me. Given I had so much of it, it was worth it. $40 plus dollars for a new inlet gasket but you could reuse and finally, a chance to torque up for leaks.
Its just the fuel cooler removal first that was the slow point pain and time to clean.
Would I do it again, use a torch and mirror first to check how much and if excessive then yes.
I don't know if this crud actually moves with fine oil spray but I suspect over time yes at the final inlet stages.
And Mike is right, allow a week for the spots on the bod!
