Where pulleys are

I disconnected serp belt and still does it

There are known issues with the valve cover causing a squeal noise so before we do anything else try , blocking the breather port of the Positive Crankcase Ventilation (PCV) diaphragm with your finger with the engine running and see if the noise stops.

Where is it

It should be the Hose that attaches to the valve cover. Remove it and plug it with your finger with the engine running.

There are no hoses but blocked a hole and sqealing started,was not squealingthis time

The common cause requires replacing the valve cover but to verify you need to check it when the noise is present. Are you saying it was not present when you checked it

Hello Ron; I replaced valve cover, got it to operating temp,no squealing still suction when removing oil filler cap,and engine changes when removing filler cap or oil dip stick,also a ticking noise

Its normal for the engine to change the way its running when you remove the oil cap. The suction is normal as well. Its from the PCV.

What causes valve cover to go bad,could catalytic cause it

I think is was a design flay and should not be cause by the catalytic converter. If you have a failing converter you will usually get a fault code and usually a loss of power.
