to reduce combustion temperatures. The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997. GM recalled 1.5 million vehicles with this engine on April 14, 2009 due to risk of fire from engine oil leaking under the valve cover gaskets onto hot exhaust manifolds. The fire could spread to the nearby plastic spark plug wire retainers on the valve cover and then to the rest of the engine compartment. GM fitted the affected vehicles with redesigned spark plug wire retainers. These engines were noted for having problems with the plastic upper intake manifold cracking around the EGR passage. The engine would then hydrolock. The lower intake gaskets and upper intake manifolds were revised, correcting all these issues.

It uses the Eaton Generation III M90 supercharger with a pulley, a larger throttle body, and different fuel injectors, different cylinder heads, as well as different lower intake manifold and pistons than the L36 uses. Both engines share the same engine blocks, but compression is reduced from 9.4:1 in the L36 to 8.5:1 for the L67. GM listed the engine output as and of torque. Final drive ratios are reduced in most applications, for better fuel economy and for improved use of the engine's torque in the low RPM range. Like most 3800 V6s, the engine is well known for its reliability and low maintenance costs. The engine is a popular choice for aftermarket modification thanks to its very strong internals and impressive power gains from basic upgrades. The engine was built in Flint, Michigan and was certified LEV in 2001. 1996 Buick Park Avenue Ultra (C-body) 1997–2005 Buick Park Avenue Ultra (G-body) 1997.5–2004 Buick Regal GS / GSE / GSX (SLP) 1996–1999 Buick Riviera
