so i took my 2010 cobalt to get an oil change nd i noticed a couple days afterwards that theres oil all ovr the bottom of the valve cover nd theres a reoccuring puddle in the block right behind the oil filter...could u guys help me fig this out...could it b that they didnt tighten the lid enuf....lemme no if any1 could give me som insight...thanks

 

Your cam endplate is leaking. There is a tech bulletin for it. Tell your dealer, they'll put dye in your oil, then on the next oil change, they see that you were right about the leak and actually fix it, instead of telling you that you're doing it during the oil change.

 

thanx for your help!!!
