Chrysler Repair: 01 Sebring 2.7L Seeping Oil from PCV Hose, crankcase pressure, pipe sealant

Question

2.7 Engine Image Hi Roland,

I have a question that is really puzzling.

I have an 01 Sebring with an 04 engine in it that has only 40,000 miles on it. The car runs smooth and the engine has lots of power.

I run syn. 5W30 Mobile 1 and I change it every 3,000 miles or less. There is no sludge in the engine as far as I can see.

My problem is that oil is seeping out of the PCV hose at the valve cover. Actually, the PCV valve its self is always wet with oil.

I took the PCV hose apart and it is clean.

There is no air blow by when I take the PCV hose out while the engine is warm and running. However, I can see oil fumes coming out of the hose (less than smoke from a cigarette butt), but on the corse of few days, my PCV system gets wet with oil and starts seeping out again.

Is that normal or there might be something wrong? What to look for?

Thanks in advance for your help.

Hi Cam,
Here is the diagnosis and testing procedure for the valve:
With engine idling, remove the hose from the PCV valve. If the valve is not plugged a hissing noise will be heard as air passes through the valve. A strong vacuum should also be felt when a finger is placed over the valve inlet.
Install hose on PCV valve. Remove the make-up air hose from the plunum at the rear of the engine. Hold a piece of stiff paper loosely over the end of the make-up air hose.
After allowing approximately one minute for crankcase pressure to reduce, the paper should draw up against the hose with notable force. If the engine does not draw the paper against the grommet, after installing a new valve, replace the PCV valve hose.
The valve should rattle when removed and shaken.
You might try using a light coating of locktite pipe sealant with teflon on the threads of the valve and put it in the manifold, tightening to 60 inch-pounds.
