Oil on Air Filter and in air intake

[alafly]

Hi Guys, my 96 Avalon is running great, gets great MPG, and I thought was doing very well at 180,000. I changed the air filter about 4-5 months ago, but yesterday (after not looking at air filter since changing it) noticed the air filter has an oil stain and prob several teaspoons of oil in the air intake system above the air filter.

I have added just a little oil between oil changes and there are no leaks on the driveway.

PCV change as first cheap fix? Are my rings stuck or broken? Should I be very concerned? Thanks so much

I think I noticed the same thing on mine, last time I replaced my air filter. I hope someone has an idea what this is.....

Clean out the PCV and check pcv hoses.

The small rubber hose from above air filter to valve cover is where the oil came from. That is the crank case fresh air supply (clean air through your filter).
