High pitched wail.
When we are rolling it screams when i accelerate. Can't get rolling as fast as it usually does. Runs and sounds great otherwise.

Check your bus to make sure my ex wife isn't hiding in it!

The intercooler is nothing more than a radiator for the compressed air.

No moving parts in an intercooler. It's just a RADIATOR. The wailing comes from a moving part. Get a LONG handled screwdriver, hold the tip to moving parts and hold the other end to your head next to your ear. Bone conduction will do the rest. It acts as a stethoscope.

Of it is poorly accelerating, check any rubber connections post turbo. The wailing may be a hole it rip in a rubber boot... Turbo whine and air escaping?
Otherwise I would concentrate on your turbo 1st.

Ditto that. Check for an air leak after the turbo. Torn boot, loose connection, etc. Noise can come from moving air.

I can't find it. Maybe the turbo is bad. It has been over heating now also.

Does it make the noise when it's stopped? What about revved up when stopped? Where does it sound like it's coming from, towards the front, rear, left right? Need a lot more info on whats going on.

No. Not when we are stopped and revved. Can't really tell where it's coming from.

Could be the water pump.

I'm thinking so too. Water pump is shot and the wail is either the bearings or the belt. Pull the belt off and see how the pump turns.

Damn. The water pump. It only screams when the turbo should be running, but I'll check the water pump. I'm out on the highway.
