I noticed today that there is smoke coming from around the oil fill cap on the valve cover on my Mustang. Does anyone else see this on their cars - is it something I shouold be worried about?

Thanks.

 

tell us more like did it start then go away, smoke color, was it just a little or alot, but its not sounding to good to start out with

 

it's is leaking from around the oil fill cap - i checked and the cap is on tight. the smoke is white, there is not a lot, but it is continuous. I let the car idle for about 10 minutes or so and it never stopped, decreased or increased.

 

that smoke is blow by into the crankcase it could mean worn rings. check your pcv valve and hose.
