I purchased a 2000 F150 4x4 last week. I have an engine knock that has me stumped. When I crank the engine cold it sounds fine. I put the truck in drive , and it knocks for around 5 to 10 seconds. After that it goes away. I am not that familiar with this engine. I am assumming that it has a cam on each head by looking at some drawings. Does this engine have lifters? My problem sounds like a weak lifter until it builds pressure. I changed the oil today with a Motorcraft filter, & Mobil 1 oil. Didn't seem to help!
Any suggestions would be appreciated!
