Those of you that have helped me so far will probably laugh that I've started another thread because of issues with my head gasket change.

Got everything back together and it started on the button, no white smoke, sounding good... revved it up and at about 3000 revs the engine makes a fairly horrible squealing sound. I'm not sure if this is new as I rarely go into the 3k range when driving and you can only really hear it with the bonnet up standing at the front. Don't think its a belt as it sounds like its coming from back of the engine.

Maybe one of the pumps? Gear box?

The intake pipe is off the turbo as I'm refurbing the air filter box. Thought maybe the turbo winding up but sounds ****ing horrible

Don't know about the noise, but you don't want foreign objects going in to the turbo. Not even small ones.

That funny noise from a 200 TDi is possibly the sound of it running!
However, to be serious, is the noise there on a hot or cold engine?
If cold, it could be the water squirting through the not-fully-opened stat, and if hot it could be exactly the same!

Sounds OKish to me, turbo whistle?

Nver easy on an audio recording but nothing sounds serious. Do you have any gasket leaks?

Where does the noise come from?
