[bHey Guys, finally got my truck delivered. Turns out the motor may not be junk after all. At start-up, the engine has a loud knock that last for about 6 seconds then seems to disapear.I let it idle for about 7 minutes, and the knock slowly returned. As soon as I "reved" the engine, the knock disappeared. So, could I have just a low oil pressure problem caused by a worn oil pump? Engine has 110,000 miles on it. I called local auto parts to purchase a high volume oil pump, but they did not list a high volume pump for the 5.4 motor. So I called melling. Melling gave me a phone number to call. When I called it, FORD Racing answered the phone. He said, how did you get this number? I told him that melling had refered me to him. Told him I had a 1999 f250, with a 5.4 motor. He said, all you need part number 6600-D46. Turns out this is a Cobra high volumer oil pump. He said, It is a direct bolt-in for the stock pump. Shipping is 4 days. I'm hoping it will take care of my problem. I could still have other issues, but a high volume pump can't hurt. Seems as if Ford Racing was familar with my problem.
Any suggestions on what else I should try?

 

perhaps online searching or surfing will do....my friend once got minor problem on exhaust with his ford..since he craves for competitive driving or racing that demands more power boost and reliability, ford racing performance parts met this qualifications... since my friend craves for unbeatable road mobility, he had his enhancements on his vehicle with it..
