I need to report my 2000 Buick Lesabre, apparently has and oil leak. While driving, you can smell oil leaking on the exhaust pipes/manifold system. I read where some engines with the 3.8l engines: Chevy's, Pontiac's, Buick regal's are being recalled for oil leaking from valve cover gaskets (when hard braking is applied) on to the exhaust system parts and could cause a fire, in the engine compartment.. I am experiencing the same problem on my 2000 Buick Lesabre. With the 3.8l engine. I would like for this to be investigated on these model Buick's 2000 - 2005, for oil leaking onto exhaust system. They should be included as well.

Leaking oil onto exhaust manifold causing burning smell and smoke which permeates passenger compartment. This car has the 3.8 series ll engine which has a recall for this problem on the regal but not the Lesabre. This is definitely a problem on the Lesabre too. Why is it not included in the recall? Often happens while driving but the last time was when I had just pulled into my driveway and smoke poured out from the hood. Using the recirculating air setting seems to help smoke from entering the cabin. Why is this not included in the factory recall!!
