General Motors says it will replace some key engine parts to stop oil leaks that have caused over 1,300 fires and four recalls of older cars.
But parts aren't available yet, so GM is still recommending that the cars be parked outside until they can be repaired.
The company tells dealers it will replace the front valve cover and gasket with improved parts under two recalls announced earlier this year.
The recalls cover about 1.4 million cars with 3.8-liter V6 engines from 1997 through 2004. Included are the Buick Regal, Oldsmobile Intrigue, Pontiac Grand Prix and the Chevrolet Impala, Lumina and Monte Carlo.
Oil can seep through gaskets under hard braking, drip onto the exhaust manifold and catch fire. Previous repairs on most of the cars didn't stop the leaks.
