On the 1997-2003 Buick Regal, buick Regals from 1997 through 2003 equipped with the 3.8L naturally aspirated V6 fall under GM recall 09V116000. The defect is an oil leak path that lets drops of engine oil land on the exhaust manifold when the car is braked hard. Should the manifold be hot enough and the oil run underneath the heat shield, the oil can ignite into a small flame. From there the fire can travel to the plastic spark plug wire channel and beyond, which is what makes an otherwise ordinary oil weep a fire hazard rather than just a mess. This is one of the longest year spans in the campaign — nearly every 3.8L naturally aspirated Regal of that generation is in scope. Supercharged Regal GS models are not covered by this campaign, which is specific to the naturally aspirated 3.8L. NHTSA lists 1,497,516 vehicles for the campaign as a whole, spanning all the GM models involved.
Common Symptoms
Burning oil odor, often noticed after hard braking
Smoke rising from the engine bay
Oil residue on or around the front valve cover and exhaust manifold area
How to Fix
Correction is free at a Buick/GM dealer. The dealer fits a redesigned front valve cover and front valve cover gasket, and takes off the engine's plastic cover and the plastic oil fill tube extension — removing both the leak source and the nearby plastic that could carry a flame. Given the age of these cars, verify the recall's status by VIN at nhtsa.gov/recalls before booking, since a prior owner may have already had it done.
On the 1997-2003 Buick Regal, gM recalled Buick Regals built for the 1997-2003 model years that came with the supercharged 3.8L V-6 — in the Regal line that is the GS-style supercharged car, not the naturally aspirated version. On these engines the front rocker (valve) cover gasket runs at higher temperatures than normal, so the gasket can degrade earlier than expected and begin letting engine oil seep out. NHTSA's consequence statement is the serious part: oil that seeps or is spilled at the front of the engine can be flung onto the exhaust manifold, and hard braking is specifically called out as the motion that deposits those drops. If the manifold is hot enough and the oil runs down below the heat shield, it can ignite into a small flame and, in some cases, a larger underhood fire. The campaign covers 207,542 vehicles in total across every model included in the recall — that figure is campaign-wide and is not a count of Regals. GM advised owners not to wait for symptoms: until the remedy was performed, the recommendation was to have any oil seepage taken seriously rather than treated as a normal old-car leak.
Common Symptoms
Engine oil seepage from the front rocker (valve) cover area
Oil dripping onto the exhaust manifold, sometimes noticed after hard braking
Burning oil smell or smoke from under the hood
In some cases a small flame or underhood fire
How to Fix
Take the Regal to a Buick/GM dealer — the recall repair is free regardless of the car's age or mileage. The dealer replaces the front valve cover and the front valve cover gasket with redesigned parts, and also removes the engine's plastic cover, the plastic oil-fill-tube extension, and the 1-3-5 spark plug wire retainers, all of which are part of the fix rather than optional extras. Because this is a fire-risk campaign on a car that is now decades old, confirm the work was actually done: enter the VIN at nhtsa.gov/recalls to see whether recall 08V118000 is still listed as open for that specific vehicle. If it shows open, book the dealer visit and in the meantime treat any oil smell, smoke, or fresh seepage at the front of the engine as urgent.
