Cracked the air intake on my 1999 Mercury Grand Marquis. It was made out of cheap plastic. I had to step on the throttle to get out of the way, and my car started steaming. Come to find out, the intake manifold cracked. It's only $300 for the part, not including labor.

My 1999 Mercury Grand Marquis has a persistant oil leak from the right rear of the engine head that is exactly as described in Ford Motor Company's technical service bulletin 02-22-07. The dealership, irvine Lincoln Mercury, has had three tries to correct the problem under warranty and have failed to succeed. The warranty expired last month and now they say that I will have to pay to have the problem repaired even though the unresolved complaint condition goes back well into the warranty period.

While driving 55 mph a loud noise was heard coming from the front. Vehicle then stalled. Consumer restarted the vehicle and pull over. Then, consumer noticed that oil leaked underneath. Consumer drove vehicle to the dealer for inspection, and mechanic determined that the cylinder head cracked, and needed to be replaced (20794 miles). Recently the consumer noticed another oil leak which appeared to be the same as that from the first cylinder head. The service manager inspected the vehicle and concluded that oil was leaking from the cylinder head again (59700 miles).
