Oil in hose to throttle housing above turbo on tdi 130

[pmdc199]

My car has been making strange noises. I took the air in take apart and to the right of the throttle housing is fine, to the left the big fat pipe that goes down to the intercooler has oil in it. Not lots but enough to make me think that is not corect?

Any ideas how oil could get there and whether the car is very unwell?

Help greatly appreciated

Oil from the oil breather perhaps?

Or sludge rather than oil? If you take the intercooler pipe off you'll probably find a bit on the inside. Don't think all the breather pipes are ever totally dry inside.

Make sure the breather pipes are clear (plus EGR valve).

None of this would account for the 'strange noises' though. Turbo problems?

Teah that's what I think I have an extended warranty may see weather thay are worth the paper they are written on

It's quite normal to get some oil in the intake pipes, it comes from the crankcase ventilation system (CCV) which vents oil vapours back into the inlet so they get burnt rather than escaping to air.

Can you describe the "strange noises" ?

it is a grunting sound when you accelerate hard or put the engine under a lot of load. It happens mainly on an incline or with lots of people in the car. I think the turbo maybe on the way out, but I am not sure

if it was the turbo it would smoke loads. mine money is on the intercooler hose banging against the fuel filter.

of the dual mass flywheel has had it, but check the hose first.

If it's the type of noise I'm thinking of, it's quite normal - both my Ibiza and Passat did it.
Under load, such as a hill etc when you put your foot down, it's kind of a cross between a screech and a hum (try to hum and whistle at the same time, it's kind of like that!!!).

Just read a couple of the EGR threads and I am seeing a very small amount of oil on the flange of the pipe where the EGR blanking plate goes ie the top of the pipe that routes the exhaust into the EGR/ASV housing:-

Prior to this I have fitted a blanking plate, but still got a CEL and could not be bothered to remove the plate so I am running with blanking plate and the EGR vacuum hose disconnected and plugged. Also I have bypassed the CCV by plugging the hole back into the inlet duct (just after the MAF) and then connecting a crankcase filter (which vents to atmosphere) to the hose which connects to the rocker cover outlet. Therefore, there should be no oil in my inlet and whatsmore, even if there was, it cannot escape via a possibly leaky EGR blanking plate because the EGR valve (with no vacuum) is permanently closed.

The other possibility is that the EGR blanking plate is leaking from the other (exhaust) side and allowing some exhaust gases to escape here, however, I cannot hear anything and why should the exhaust gases be oily?

Maybe my imagination, but the exhaust seems a little smokier than usual, although there has been no drop in power or torque. So, just where is this oil coming from? It is not a great amount, but I have cleaned it off with a piece of kitchen roll only to see it back the next day. Do you think that my CCV mod is possibly not letting the crankcase breathe enough and therefore oil is being pushed out somewhere else?
