Found the Screaming sound; vacuum leak under the inlet pipe.  Apparently, I
have left a piece of the old gasket's paper on it.
But first I took off the belts to see, and when it was still going, I took
off that double pipe and fixed it.

Now, I'm wondering why the engine is pulsating as it's idling.  Would I need
to use a different ECU?  Raising the idle is not helping so far.

Thanks to all,
Zoltan

Hi Zoltan,

Loose belt?  I doubt it's a bad pump, that would be a real bummer.

Hi to all,

I have just put an older engine in with new water pump, into a 1.9 van.
Although not immediately, but very soon a high pitch screaming sound is
coming from the left side.  I’m suspecting the new water pump, but someone
else would say otherwise.  Any ideas?
