oil in intercooler

[FullFlxd]

Hey guys,

Yesterday I installed the exhaust on the 09 patrol. Whilst doing that I had to take the pipe off that goes from turbo to intercooler. I found a fair bit of oil in there. I remember reading something about it but can't find it when doing a search.

Can someone please remind me what the cause is and possible fixes??? Also after driving around a bit testing the difference I noticed a little bit of oil sitting at the tip of the exhaust (definately engine oil mix with exhaust soot) is that ok or is the turbo playing up??

Cheers

P.S does anybody know whether patrol4x4 forums are de-bugged yet???
(not that I don't like this forum)

Check the breather and inlet pre turbo for oil.
If it is oily a catch can on the breather line is a solution.
If that is oil free i would be looking at the turbo itself could have a bad seal or be worn to the point oil is escaping through a seal.

Cool I'll check that out

Does anyone have pics of where to block egr on the crd's? I had a look but couldn't figure it out. I think it throws codes but i was thinking partial block??

By the way the trol has on done 27,000Km's

yes it is, and im not taking it to Nissan any more services don't trust them! It just costs me money when they try to find what the problems are while telling me they don;t know

http://www.nissanpatrol.com.au/forum...ng-MAF-sensors . Have a read of this post , you will have to do it if youve got oil in your intake .

the MAF in the troll is right after the air box not after where the breather connects to the pipe , thus has no oil or soot on it at all. I checked it earlier.

I didi notice something interesting and that is the Air box has a small hole in the base which opens the box to water intake if you were to do a river crossing. In my case mud last weekend. Do any of you with have this??

If it (turbo) was pouring oil in to exhaust it would be smokey. You've mentioned exhaust fitment it is quite possible residual oil from the new exhaust or installation perhaps. Oil in the intercooler is probably from the CCV (Closed Crankcase Ventilation) breather it is a typical find on all turbo diesels which don't have the oil separator (so called catch can) fitted. Typical bloody car manufacturers "cheap skating"!
Fit one ASAP.
The small hole on the base of the airbox is a drain/vent hole and it is on every unit. Feel free to work out an alternative for it but blocking it outright is also not the smartest thing.

Im not much of a reader, but I take it we are talking about a ZD30. Overboosting is very common on this engine.
You can add an Oil/Air Separator or Catch Can to reduce the amount of crankcase blow-by oil that enters the intake system and contaminates the MAF sensorcan, a turbo timmer would be nice too.
Also, to be sure, chk your compression on each cyl, specially #3 and #4 to make sure no other problems are soon to come.
Forgot to mention that adding a manual boost controller would be nice, toghether with pyro and boost gauges. AME are good an dependable...

Could not be the intercooler itself? Mine is cactus at the moment. It is very dirty with what is obviously oils and suit and other shit. My mechanic tells me its a problem that will defiantly happen on 3L.
