Two problems related to gasoline engine have been reported for the 1999 Ford F-350. The most recently reported issues are listed below.
I bought my truck in Feb. Of '99 and change the oil and filter every 3000 mi. . I use motorcraft parts and I only use the truck for hauling soda drinks for my business. Needless to say, the truck is still like brand new!! from the very beginning,the engine would develop a slight knocking about 10 to 20 seconds after initial start-up in morning. As the miles increased, so did the length of time the knock took to go away. The knock has gotten louder and longer and the dealer where I took it on sat. 3/17/2001, told me I need new motor!!.
1. The engine is starved of air when driven on snow and ice. Snow gets packed in the air cleaner box and freezes. The air intake is pulled from the wheel well. 2. Road debris and rocks load up the bottom of all doors. Weatherstripping is required.
