Hello to all, I have a 2008 Pontiac Grand Prix. Traveling along I noticed blue like smoke, obviously I check it out.  There is oil all over the bottomof the car. I checked the oil level and was only about a quart low. The leakage appeared to be located to the passanger side. The smoke was hitting the exhaust piping, this is why I had blue smoke,however I can't locate the leak. If someone has had this issue or now of a location it could be leaking. I would so much appreciate it.  Thankyou......................................Steve,

Steve, the 3800 is notorious for two places. The first was valve cover gaskets, but the more obscure place is the intake plenum on the front of the motor. Which is the passenger side. It leaks where it is sealed at the block. Look for a oily wet area behind where the serpentine belt is. Likewise do the same at the font and rear valve cover. If you can’t tell where it is for sure, spray the Motor down with Gunk engine cleaner, hose it down let it dry and then run it. It should than become obvious.

Thanks so much for the fast response. I am planning on working today on this issue. I will check both recomendations.  Google garage web sites indicated it could also be a oil press. sending unit or a oil level sending unit. How do you feel about those recomendations. I am trying to gather all intel I can as I only have one car and once you pull it apart your stuck. Anyway I do appreciate your input as well.............................Steve,

Obviously anything that involves oil could be responsible, but what you describe sounds like a none pressure side of oil! If this is the case the two things I described would tend to be my thoughts. Also both of those are technical service bulletins on the 3800 and well documented as a problem.
