greasy turbo pipe (T4) = lack of power?

Ive had my v40 for about a year now, & for a long time now its felt a bit Lame,
also for a long time ive noticed that the only part of the engine that ever has any oil on it is the fat rubber pipe that comes directly out of the turbo, it allways seems to have a film of oil on it, I wipe it off, & it reappears.

I took it off this evening, and inside the pipe is rather dirty looking engine oil (only a couple of ml) & the exit port of the turbo looks clean on the inside.

so..
could the pipe have become porous? unlikely

is the oil just blowing out from the gap, ie jubilee clibs not tight enough?

is that amount of oil ok? the car drinks about 4L every 5000 miles but no blue smoke from exhast as far as i know

Alfonz,

Will have a look at mine tomorrow and let you know...

4L sounds a lot. Mine uses about 1L every 2-3,000, and does burn it visibly after idling for a few mins when you pull away agin.

That is excessive! My car does not consume a drop between successive oil & filter changes so I think its something worth getting checked out.

so wheres it going then? engine bay is dry, Can only be going out of the exhaust? because shurely i cant be loosing 4L into the intercooler.

btw, have cleaned the pipe and turbo outlet, checked the pipe for leeks and refitted, seriously tightened up the jubilee clips,

uptake on the turbo is much better now, and sofar the pipe has stayed dry, so i guess that that was just leaking air/oil into the engine bay,

someone on another forum suggested the oil in the pipe may have just been from crank case ventilation, wht you think?

I have a V40SD(2002) The pics look like the plastic pipe from the intercooler to inlet manifold (I know mine is a diesel and yours is a petrol)? If they are, mine has a slight leak too, just enough to attract the dust and dirt etc on the inlet manifold near rear top of the motor. I've taken the plastic pipe off and there are traces of oil in the pipe too. My motor has done over 73K miles now and doesn't use any oil between changes (I change it every 6K). I've been told by another V40SD of the same age, his has the same level of leak and has been told by someone in the know that this is not un-common and don't worry. I have a feeling that it has something to do with a crank case breather as there is a stainless steel pipe coming from the back of the block (as far as I can see) to the under side of the inlet manifold that may be a breather pipe??? Mine just flew through it's MOT at 72K miles and the immissions were lower than last year.

Hi Mark,

yep, petrol

no, its a rubber pipe that connects from the turbo to a plastic pipe that go's over the top of the engine to the intercooler

[Mark]

Hiya,
Hmmm. The pipe that goes from the turbo on my SD goes to the bottom of the intercooler around the side of the engine. The other side of the turbo has the pipe going to the air filter box. The pipe I was talking about comes from the top of the intercooler to the inlet manifold.

On your's is the oiled pipe upstream of the turbo (Air filter side) or down stream of the turbo (inlet manifold side)? I was wondering if you are getting oil mist from the turbo lubrication system?

Mark

directly downstream, its between the turbo and the plasic pipe that go's to the bottom of the intercooler, more round the side than over the top, i misslead you there i think

found these pics on the net, have stuck arrow on to show position

I'm no expert, but I rekcon that the pipes we are talking about are for doing the same job on both of our engines. If that is the case, I've been told by another guy on the this site that there is no need to worry about the slight oil leak. I'm not loosing any power though, or using any oil between changes.

I'm not sure if this is helping you out at all? Sorry.
