Oil in induction air/system

Hi everyone

Since curing the overheating incident the P38 2.5 diesel 2001 has been trouble free for a a few thousand miles.

I fitted one of those erg bypass kits, removing the penny block and the old valve, not sure if it was placebo but it seemed to run a little better since fitting.

However I checked under the bonnet today after a London to Cornwall run and there was a substantial oil leaking from where the new bypass tube hits the intake manifold (metal to metal)

There just seems to be so much oil in the induction system.

I know this has been covered recently but this just doesn't seem normal

How can I cure this, there is a weep on the turbo outlet side, I did not Hylomar it when I assembled it about 13000 miles ago, where is all this oil coming from or is it normal for an engine with 140k on it.


Thanks in advance

No need to spend silly money on a EGR bypass just clean out the old one make sure the spring holding it closed is good and pull the vac pipe off it. Oil in turbo hoses is normal, but excess oil in turbo pipes maybe due to gummed up oil separator and vent valve in cam cover. Or a weeping turbo seal.

Thanks for the reply

Yes I realise the kit was a load of tosh, just looking to tidy up the area really. When I removed the old erg it wasn't all caked up with soot as to was prior to blocking the egr feed pipe so not much restriction but it was wet with oil

The vent tube just goes straight int the induction system and there appears to be no AOS present?

How tricky is it to access the turbo seal, is that a major?

Thanks again

You can't do the turbo seal unless you really know what you are doing. Turbo out a stripped down. Oil in turbo pipes and inlet is normal. Swimming in oil is not normal. It depends on the severity.
