In my only other post I asked about oil in the spark plug tube, and was told to change the valve cover gaskets. I am waiting for them to arrive in the mail. 

The car is running kind of rough at times, though is still very drivable. 

I have a 75 mile commute, and not a lot of options while I wait for the parts. 

Am I going to destroy my engine if I drive it a few days this week? 

 

The engine may be fine, but the cats may overheat. And they are $$$ to replace.
