PCV VALVE QUESTION

1997 Acura Integra

1997 Acura Integra 4 cyl Front Wheel Drive Manual 170000 miles

I just have a quick question about the PCV valve on my car. I'm doing regular maintenance and a 3,000 mile oil change, and I'm considering doing the PCV valve and grommet simply because I don't know how long it's been in there. The car runs very well, does not burn oil whatsoever, and idles perfectly fine--so the replacement is simply because it's time for it to be done. I popped it out to examine it today, and it was almost brand new looking except for a somewhat thick film of clean amber colored oil around the neck of the valve (the part that actually goes inside the valve cover)--is a layer of oil to be expected on it or is oil not supposed to be present at all in this portion of the valve cover? The area surrounding it seemed to be clean of oil.

Hi Wgrace07,

For a vehicle of the age and mileage, some oil around the PCV is normal. Blowby gases would carry some oil with it to the PCV when they are being pushed to the intake.

There is nothing to worry about.
