Turbo questions

[ste68blue]

Hi guys can anyone offer some advice please?

On friday i changed my MAF and whilst i had it off i noticed what appears to have been an oily looking stuff inside the intake pipe from the MAF to the turbo.

I have to say that the intake into the intercooler always has an oily substance on it too and i do plan on cleaning the intercooler out with petrol.

Firstly, should i be concerned by the oily stuff?
Is it possible for a DIY mechanic to repair or refurb the turbo or is it a matter of buying a refurbed one?

Any help or advice is much appreciated

Cheers
Stephen

I think everything around there is always a bit oily, more so with the "wrong" grade of engine oil, don't worry about it!

Hi thanks for the replies.

This blow by control valve....does the post say i can block the end going to the turbo or even fit a catch tank of some kind?

How do i clean this valve out for a starting point?

i have used a splash of petrol to clean this!

A quick update a possibly a few more questions may need answering...

Today i took off the intercooler, inlet pipe, blow by control valve and other associated pipes to wash and degrease.

Whilst i was cleaning the intercooler, as expected the degreaser and the petrol i used to wash it out turned horribly oily, i rinsed it out a good few times until the fluid coming out was pretty clean.

What i did notice also was that when i cleaned/ washed the blow by valve the fluid easily poured out of all three pipes, does this mean the valve inside is stuck open?
Can i simply block the pipe off that goes to the inlet pipe towards the turbo, stopping any future oil contamination or could this cause me problems?
If so how do i free it as it doesn't look like it can be dismantled without breaking it?
I checked the turbo turbine on the inlet side whilst i had the pipework off and it spun freely although there did seem to be a little movement on the end of the shaft, is this acceptable?

So, just to put it all back together and try it.
