I have a 2000 F150 5.4L. The right side head was replaced at 24000 mile under warranty due to oil leak. The diagnosis was defective head "problem solved". Now the truck has 49,000 miles and is out of warranty and again leaking oil from the right side head. The truck is again at the dealership who tell me it may cost thousands to fix. I contacted Ford about assistance and was bluntly told the vehicle was out of warranty and it was my tough luck. I know this is a very common problem that Ford will not step up and address. Has anyone had any luck getting Ford to help out? Any lawyers out there need a good class action lawsuit? I hate to say it but I've bought my last Ford!
