Sienna :: 2002 - Dripping Oil On Ground?

I have written a lot over past years about my 2002 Sienna. It has always been very low on oil consumption, even over 200,000 miles.

In Sept/Oct during my annual visit to the States it used a quart in 3200 miles, which is more than in the past.

Last week, for the first time ever, I saw oil under the car on the concrete. First thing I looked at was the drain plug. Solid, and no oil on it.

Then, the filter. Ditto. No oil on the bottom nor under it.

I looked further and there is oil around the edge of the metal part on top of the motor which is obviously the valve cover. So, I am assuming the valve cover gaskets are oozing based on where the oil is visible.

But, first, I will check to see if the screws on the cover are loose, just in case.

As time passes, I will look around in other places. I realize a quart in 3200 miles is not the end of the world, but if I can make it better, why not?

If I can, I will wait until my next trip to the States, next October to do repairs other than checking for loose bolts/screws.
