#287 of 1186 Engine noise/knock goes away at cursing speed
Feb 08, 2008 (5:04 pm)
My 1990 International 7.3L Diesel (Ford F-350 box truck, 190K) just started making a noise that seems to be coming from the engine. The truck is running a little rough at idle and the noise seems to come and go. While driving it gets louder during acceleration (not extremely loud and slight power loss) after getting up to speed the truck runs and sounds fine. No overheating. No oil in water or water in oil. Oil pressure fine. The only other thing is there seems to be a stronger exhaust smell. Exhaust pipe and manifold look fine, no signs of leeks. No hard starting.
Any help would be greatly appreciated.
Also can anyone recommend a diesel mechanic in the Fort Pierce, Florida area.

Check the engine oil for a fuel dilution. You may have an injector going bad. If the oil smells like fuel get it repaired quickly. A fuel dilution can wipe out the main bearings very quickly. The Ford dealerships seem very good with these engines. Good luck.

You should always replace axle-related items in pairs. Brake Pads, Calipers, bearings, brake cylinders, etc.
First and foremost, for your's and everyone else's safety on the road: you want the vehicle to steer and stop evenly and straight. If you only replace one side, you could find that the new side now spins freely, but the other old side spins slower by comparison due to wear, etc., and as a result your truck is pulling to one side or the other. Could make driving a challenge......
Second, if one side failed, the other usually isn't far behind.
70K miles isn't unheard of. Have the bearings ever been cleaned and repacked with grease? It's usually done when the brakes are serviced. If they weren't, then dust and moisture contamination in the grease could've increased bearing wear leading to a failure.

#291 of 1186 Starting to go bad i think
Feb 23, 2008 (12:23 pm)
I have a 2000 F250 7.3 (the real powerstroke, haha). I bought it with 209,000 miles on it and i havent had any problems with it besides an alternator around 225,000...until now. Around about 240,000 It started having a hissing sound come from the passenger floorboard. When i got on the pedal it would continue, however, when it stopped i noticed a slight gain in power without changing pedal pressure. It only happens when its cold outside. Now there are more little things going wrong with it. I have a hum when i accelerate, when i turn, and when i brake. I can "feel" the hum in my foot on either pedal. I was thinking it had something to do with the booster but im not sure. All fluid levels are OK.
Ive always been a Chevy man and i have since been converted to a Ford man by owning this truck. It now has about 250,000 miles on it and i tow a 12,000lb. mini excavator around 2 to 3 times per week. I drive it pretty hard, but not hard enough to break it, this is a tough truck. I change the oil at least every 5000, air filter every 2 oil changes. If someone could give me an idea on at least where to start it would be appreciated.

I have a 1999 that makes the same noise when its cold outside.I think it is the turbo wastegate. I bought mine new and it has always done it when it is cold.

#295 of 1186 F-350 Diesel
Feb 28, 2008 (4:07 pm)
I have a 2004 F-350 diesel. 6.0 Bought it when it had only 18,000 miles on it. Its been in the shop more then its been on the road. When I stop at a light or stop sign or just get out of the truck a few minuets it will sputter and try to quit running then idle fine again. Sometimes it will try to take off by itself at a stop light or stop sign momentaraly. Ford replaced sensors, fuel peddle, and the whole entire wire harness under the hood. Truck still does it. Its still under warrenty but have to pay the deductable every time. With all the records in hand, can this piece of junk be a lemon? thx

I have 03 F250 Diesel 6.0 that leaks coolant out of the reservoir cap.
DO you have any information about this problem.
