Hi gang..so I got a 2007 tl-s that I recently acquired that I've put 1k miles on... today, after not driving for a week or so...there is smoke coming from the front, near the oxygen sensor, is this just a leaky oil gasket, ( it is oily) burning off on the exhaust manifold.... And, is this a big deal/ repair....thanks in advance

It appears that your head cover gasket, #6 below, is leaking.

 

Valve cover gasket. Pretty easy to DIY if you have basic tools, time, and common sense.

 

Thanks.. I have all that stuff... Except, I've been told, the common sense.
I'll watch a few videos

 

was it the valve or head gasket I’m having the same problem

 

Hi...it was the valve cover gasket... thankfully
