Hi all i recently got a 01 b4 twin turbo. I dont know too much about turbos as uts my 1st one ive ever owened but its got some issues the small turbo passenger side blows smoke from it and under neather it is pissing out oil all over the ground. Any help would be great thanks.Ok no worries

step 1: find and fix the oil leak.

 

There's an oil line goes into a banjo bolt, then a return line.  If its pissing out (high pressure?) - then likely to be the banjo bolt side.

 

Find out if the leak is just external (hopefully.. ) or internal

  -- is the smoke just the oil burning off the outside of the exhaust?

  -- pull off the intercooler and look for evidence of oil coming from that turbo into the intercooler.  If there's oil there, then you need a new turbo or get the turbo rebuilt.

Yeah there is oil in the intercooler going into the intake manifold

Yes - there always will be some.. mostly from blowby via the crankcase/PCV.

 

Check if there's any significant amount of oil in the plastic piping from the primary (passenger side) turbo to the IC or the turbo outlet. (The secondary piping often has oil pooled in it - this is where the blowby stuff tends to collect because the secondary doesn't get used much).

 

If there is oil in the primary outlet - your turbo seals are probably blown and it needs a replace/rebuild.

 

Cause ?  Just shitty maintenance / old age / blocked primary oil feed filter, or maybe the banjo restriction has been screwed with and the primary was running with too much oil pressure.

 

ps: you don't have a dodgy catch-can installation that's been done wrong, do you?

Good time to start some reading.

Thanks mate my mechanic has told me bith turbo need rwbuilding and 2 rockwr cover gaskets and left cam seal

[duncanm]

Wot Kong says! also you'll find you can probably source 2 second hand turbos cheaper than a rebuild. Either locally or via yahoo JP: http://buyee.jp/item...tion/o147008381

 

If he's going to do cam seals - make sure he pulls out that primary oil feed filter and gives it a clean (it can only be accessed after the cam sprocket's taken off).

It was running alot better when i 1st got it but not the way it should have ran im gonna get a second opinion on it

[Dylan720]

Ok mate thanks heaps i will do that tomorrow and let you know if your close enough to my locarion maybe even work something out gibe you some $$$ to have a look you seem to know a lot about them

[Dylan720]

So my mechanics quoted me 5800$ for everything to be done on it im pivking it up tomorrrow and ill find out why the engine lights on im gonna take it somewhere else cause that cant be right

[cowie165]

Wow! There's a decimal point error there :-)

[Jimbo]

Could buy another B4 for that much!

[Dylan720]

Thats right im thinking about another second hand motor with the turbos you can get them with under 100k for 1800
