2005 Chevrolet Monte Carlo Owner Comments

Monte Carlo

  • miles


My engine (V6 3.8L 3800 series) is leaking oil on the engine. My mechanic told me this yesterday (11/2/16) when he replaced the plastic elbows as I had antifreeze leaking from them. He said the 3.8 L engine has a recall for this, oil leaking from the valve cover gaskets and said Chevrolet has a recall to replace them. I do remember seeing this recall online somewhere, but have not seen it while searching the last two days. My mechanic old me it will cause a fire. I have 87771 miles on my car. I have to add a quart of oil in between oil changes. I have had to do this since I purchased the car 6/2008. The car has been leaking oil for awhile now.

Monte Carlo 6-cyl

  • 49,400 miles
I have been the sole owner of this 2005 Monte Carlo. I had an oil leak and the Chevy dealer ran a dye test to see where the leak was coming from. The test show it was the rear main seal that was bad. I have taken my car in on all scheduled oil changes, running mobil 1 synthetic (recommended) and having all scheduled maintenance done. I do not feel a rear main seal should be going out on this low mileage vehicle (under 50,000 miles). I feel this is a defect. I called the Chevrolet customer care line, and they were no help.
