I have a 2003 cts with a oil leak on the right upper back part of the engine against the fire wall. Both valve covers gaskets have been changed two months ago. the engine was steam cleaned to see where the...

That's a blowback/EGR hose. Excess gas from the compression in the piston goes back in the crankcase and passes into the valve train/cover and the gas by means of EGR valve was sucked again by the intake manifold.

That is why there is oil in the hose, excessive oil means a blocked EGR valve. Either clean the or replace it with new one.

Hope that explains everything.
Thanks for asking FixYa!

Where is the pcv valve located ?

It is a hose with a metal/plastic made one way valve. Locate on top of your engine oil cover ( you could see it by the side of the cover ), the air which came from the over excess compress gas from piston, its called blowback.
The blow back gas goes through that PVC valve and goes back to the intake manifold.
Just look for the hose from the cover of the engine and connected to the airfilter intake hose! Look at the hose closely between end you will see the valve.
Hope that helps you out!

I have changed pcv valve twice and still getting oil in breather

The PCV valve does not control the oil situation, it just keeps the pans and valve covers from blowing off during a backfire. Excessive Oil in the breather is a result of excessive crankcase pressures, usually due to a worn engine, specifically rings.
SOME oil is normal, especially if you are loaded heavily and hard on the throttle.
There is a tester that measures crankcase pressures, but usually some other manifestation shows, like excessive oil consumption.

the PCV system draws crankcase fumes into the intake at idle and lower throttle situations. air going into the crankcase is filtered by the small PCV filter, where the oil shows up....

At highter throttle and lower intake manifold pressures, the system reverses, the PCV valve closes, and the fumes exit the crankcase VIA the breather filter. All of this is normal.

It costs tons less to periodically clean or replace the PCV filter.

Oil in air filter wot causes this car in qustion is a jag xj8

This issue is caused by crankcase pressure issue.
Normally filtered air enters the engine, runs through the crank case and then is pulled into the intake through the PCV valve. Durning hard acceleration, the PCV valve closes (to prevent explosion of fumes in crank case and blowing valve covers and pan off) and the PCV system reverses, with fumes coming back through the filtered intake.

Usually there is minimal oil that gets back into the air cleaner.

So, when somthing goes wrong, like excessive blow by, for example, the crankcase pressure overcomes the PCV valve and intake of fumes capability, and oily starts showing up in the air filter.

Investigate the crankcase pressure and PCV system.

Could that be causing oil in intake and exhaust

Look at center of engine, at back, and you'll see a black tube coming from drivers side rocker cover, to a short black piece of rubber hose like a 90 degree elbow (which usually cracks or collapses and causes problems).
That should attach to your PCV valve.
