My 540 died in last Friday's monsoon. Only about 8 inches water, but apparently enough to allow water to flood the combustion chambers. I tried to start several times after the water subsided, only to be met with a gruesome, very short ker-phung, ker-phung sound. My mechanic thought I'd need a new engine, but was surprised to find that after removing the spark plugs, then starting the vehicle, about a gallon of water spewed out the exhaust pipe, and things seem to be back to normal. Obviously there were abnormal stresses on the timing chain, tie rods, and crank shaft. My question to you all is: have any of you experienced anything similar? Are my engine's days numbered? Should I ditch the car for a new model. It is a 2001 with 55,000 miles on it. [target]
