several questions about a 94 F350 drw 7.3 turbo
Hi, awesome forum! Thanks to all who contribute. I just got my first diesel F350 and I have several questions for some members that might could help.
The truck is a 1994 model with the turbo diesel engine, and has been sitting for about a year. I put a new battery in it and it started right up. Immediately, white smoke covered the whole truck like the thing was on fire. I let it idle for a few minutes, but to no avail. I checked the oil and found that it had about 2 quarts too much, so I drained it and refilled with Rotella 5w-40. Round 2... I started it back up and let it idle for a few minutes. It still blows white smoke, and this time I noticed a healthy dribble of fuel coming from the oil pan area on both sides of the truck. I shut it back off, crawled under it, and noticed a heavy accumulation of oily, greasy stuff on some sort of fuel system component (possibly the high pressure fuel pump) on the inside of the frame on the drivers side, near the bend close to the firewall. If the truck sits for a few minutes, I can start it and it doesn't appear to leak. If it runs for a few minutes, it starts leaking again. It white-smokes all the time it is running...So, here are a few questions, and thanks in advance for the help!
1. The vin indicates a 7.3 liter engine, turbocharged. Is this a Ford engine or did some other company make it?
2. Is part that is leaking fuel the high pressure pump? (see description above)
3. What causes the white smoke? Is there an official flowchart to diagnose it?
4. My truck has a red LED light on the panel opposite the headlight switch. I cant tell if it is factory installed. If I rev the engine, it will flicker on for a second (occasionally), then go back out. Any idea what that might be?
