Ive got some issues with my 07 impala LT

I have a 2007 chevy impala LT with the 3.5L Flex Fuel. When my car sits for a while the oil leaks out the bottom of the engine pan. my question is what could be causing this? and what will i need to replace?

Where is it leaking from
If it's the drain plug then I would suggest you remove it and see if the O ring is pooched/cracked/missing whatever.
If it's running down the sides or from the front or rear then pan removal and new gasket(s) are required, or perhaps front or rear crankshaft seals.
But
Sounds like O ring on the drain plug to me, or perhaps the oil life sensor ( if that is on the 3.5)

Late to the party, I know. But the oil filter adapter is also a problem area.

Oil Leaks common?

How common is it for a Chevy engine to develop oil leaks? Knock on wood I've had Hondas go well over 100k with not even a drop leaking. My 2007 Impala 3.9L has been in the shop no less than 5 times with oil leaks - 2 head gaskets, 2 crank seals and 1 oil pan gasket. That's in addition to twice being in for header cross-over pipes leaking coolant. The service rep at my stealer told me it's okay because it's warrantied for 100k - but now mine is out of warranty and now I'm paying for repairs. He seemed to think it was quite normal that each repair only lasted 12 months. My first leak developed at just over 50k. He couldn't understand why I would think of keeping my car after 100k - his response was that most people don't drive a car past 100k - they get a new one. He's losing me as a Chevy driver.

Your service rep is an idiot, so hopefully that answers all your questions. Repairs should last well over 12 months, that's pathetic.

Sorry to be late to the thread as well, but I don't usually work weekends and am catching up on my return to the office today!

48Lowes48, I can definitely understand your frustration and would be happy to set up a service request (case) for you that would allow me to get in touch with your dealer to work towards a resolution with you! Simply send me a direct message with your name/address/phone/last eight of your VIN/current mileage/dealership info, and I will be able to create that case for you. (If your Impala is still in the shop and you would like more immediate assistance, my phone hotline counterparts at our Chevrolet Customer Assistance Center are available 8am to9pm ET at 800-222-1020 and they can create a case for you as well!)

Best,

Katie

Sorry, I no longer take my Impala to the dealer since it is out of warranty. Nor will I ever take it to that particular dealer again. If you check the earlier threads I posted one of the other Chevy Customer Service reps got involved and pretty much dropped it when the dealer service manager stated the repair is warrantied for 12 months. Yes a repair may be warrantied for 12 months but when an engine keeps developing new leaks after 12 months has elapsed, then there is definitely something either wrong with the engine or the technicians working on the car or both - in my opinion. Since I am the consumer it's my opinion that counts - not yours and not the dealer's. I will let my decision dictate my future actions (read: no longer buying Chevys and certainly never deal with P.O. Chevy again).

Never purchasing a Chevrolet again because of one bad car is a bit hasty. I know people don't buy cars regularly but I wouldn't avoid the company for one bad vehicle as its not the norm.

All companies have their lemons.

48Lowes48, thank you very much for the clarification. I can understand your perspective and am really sorry to hear about your past frustrations; I'll be sure to search for the past thread you mentioned. GM takes comments such as yours very seriously, and I have documented your concern along with your comments where many General Motors departments can view it. General Motors relies heavily on loyal customers and I hope one day we may be given the chance to earn your business again

Best,

Katie

Kingnutin, replaced the the oil adapter seal and torqued it to 18ft #'s all is good. FYI the dealer sold it for like $14.00, parts store $27.00. Oil leak is gone for now. Thank you for the information.
