Correctionar was smoking today even with the A/C on . This weekend I'll change the oil,the rear valve cover gasket and check the oil returns back there.

Were the proper O-Rings installed on the PCV?

Yes....but I will recheck that today.

When I take the PCV out it doesn't smoke.....but of course it whistles at idle so I put it back in.

When I took off the upper intake to check for proper PCV tube position I noticed oil filling the left rear of the lower intake same as it was before I replaced the gaskets. Is this NORMAL? This is my fifth car with the 3800 SERIES 2 and I never had oil burning prior to this one.

left rear of lower intake oil filling is normal right were alt mounts
and right front near thermostat
every one will leave oil there
in those 2 areas

Why does it build up there?

it does because those 2 areas are recessed and the vacuum of the engine cant draw it in to be burned if you notice the whole lower intake has a oil film when you pull off the upper intake all 3800 do this its normal

PLEASE HELP..........SOMEONE MUST HAVE EXPERIENCED THIS PROBLEM. How about some ideas Mike from Elmira?

Did you put a O RING around the base of the PVC valve?
