Hey, I started my car to let it warm up and when I came back the snow behind the muffler was black for about 3 feet. I'm thinking this could be the rings now cuz I just had the head done about two months ago. Keep in mind this engine has 143k miles now. any thoughts? thanks in advance!

 

anyone?

 

anyone?!?!

 

if you really want the right answer do a leakdown test.
