2000 Chevy Prizm with Oil Caked on Spark Plug
 

I have white/gray smoke coming from my exhaust when i start driving and it disappears after driving awhile. The smoke does come back if I idle too long.

Below is an image of my spark plug

I am putting about 2 quarts of oil in my car every 2-3 weeks. I drive about 50 miles through city/highway streets each day. I have about 160,000 miles on the car.

I don't remember seeing a pool of oil in the cylinder. That doesn't mean it wasn't there though.

I took it to a mechanic they charged me $700 to fix the gasket, it worked well enough for about a month, but i still have the same problem.

Is this a gasket issue; pcv valve; cylinder; I am not a mechanic...can anyone help me?!

The problem is most likely valve seals however with that high mileage you likely heed to replace the engine.

Thanks. That's what I figured. I can replace the spark plug which helps for a short time but, is there any time of engine sealant I could use to tie me over until I could afford a new car?

There is no miracle in a can. You could spend/waste a few dollars here and there but the likely hood of any of the helping much or for very long is slim.
