Alright well whenever I have my car out for a while oil starts to drip onto the exhaust manifold (right next to the cat). I am assuming this is the oil pan gasket? What else should I look for before buying a new gasket? I already checked drain plug. thanks

 

Check to see that the bolts that hold the oil pan are tightened to specs.

 

And that the Oil filter is on properly, tight and no double gasket or anything weird like that...

 

yea its very possible its just the oil filter
before you go buying parts, just jack the car up and LOOK
