2004 Chevrolet Impala. Consumer writes in regards to difficulty getting parts for engine oil leak on exhaust manifold recall.
After parking my car, I just happened to noticed smoke coming out from the front of car and I was fortunate enough to have a dry chemical fire extinguisher available to put out the flames. It appears that there was a valve cover oil leak that had dripped onto the exhaust manifold that caused the oil to ignite into flames. Resulting damage that I'm visually able to see was to all spark plug wires, engine coils, plastic engine cover, oil dipstick, right engine strut, wiring harness pigtail going to coil pack assembly and under hood insulation. I will not know full extent of damage until I attempt to perform the repairs myself. I have photos if someone would like to view them. Also, the mileage I listed of 99,400 is approximate, it is not exact as I am not near my car at the moment.
