Oil In IC Pipes & in Air Box

My car has been really down on power recently and has been feeling very laggy until 5k so I decided to take a look under the bonnet to find out if everything is ok.

What I found was lots of oil inside the IC DV take off & inside my R2D2 DV itself. Also some oil in the stock airbox and on the stock recently replaced filter.

 

Also there was a patch of oil around the turbo closest to the front of the car. Also there's more oil inside the IC pipes.

 

Can someone confirm if this is the oil seal on the first turbo that's gone?

 

Am I right in saying that the 1st turbo needs replacing and the FMIC needs a clean along with all the pipes?

Id say the boost leak in the first picture is why its a bit down on power. When did you last remove the pipework to check it? Not sure its the oil seal as the one that goes is in the exhaust. Checked your PCV valve, see if its stuck?

Deffo remove the pipework and cooler and flush it out.

Do you use much oil?

It's not a bit down on power but it's none existant until 5k revs. Boost leak in first picture? I can't see any boost leaks on it afaik. I've checked & the FMIC was recently fitted so the pipes are all connected ok. I've checked all the clips.

 

So all that oil on the right side of the first pic is not from the turbo?

 

I checked the oil level and it seemed fine. Will check it again soon.

 

The last time the pipework was removed was a month ago when the FMIC was fitted.

 

The turbo closest to the bulkhead seems dry as it should be.

The first picture, that spray pattern on the heat shield? Thats a boost leak, the oil in your pipework is getting blown out. Id check the condition of that corrugated rubber pipe, I suspect a hole.

The PCV is a valve in the intake cam cover that stops boost pressure entering the vent system, if its stuck youre gonna get alot of oil in the intake system as its blown out of the engine ;)

i had a similar problem with my GT4,it gradually lost power oil in the pipework & air filter duct smoke coming from the bonnet vents in slow traffic, did a compression test & no 2 piston was about half what it should be, so might be worth doing a compression test if only to rule it out
