    the coolant is down just slightly and the oil seems to be topped right up...i did some research and found some ppl say it could be the egr ... i didnt know diesel engines had an egr... could this possibly be the problem?

White smoke would be an idication of coolant in the combustion chamber. Check coolant level,check oil to see if it is a milky color.May be a leaking head gasket or possible oil cooler leaking. Let me know if this helpful

    Oil in the coolant would indicate oil cooler leak

  • Crhen Feb 06, 2010

    The 7.3 diesel does NOT have an Egr. The egr coo;\ler leak is a problem with the newer 6.0 litre. I believe somehow coolant is getting into the oil. Just happened to think of another thing. Could be an injector cup with a pin hole,Allowing coolant to enter the combustion chamber. Each injector in this vehicle sits in a brass cup pressed into the head. This takes a knolegable mechanic with the right tools to repair.

SOURCE: 99 Ford F350 Powerstroke diesel; misfire code; loss of power

The first thing i would check is the Glow Plug Relay. Depending on your engine there should be (2 solenoids, or just one) sitting on the top front a little to the right of center. (right bank of engine that is) If you have 2 of them one should be smaller and it is the one furthest to the rear of the engine. It controls power to your glow plugs for cold start up. When you turn the key to the on position the 2 larger wires should both have power. When the ignition is off only one wire should have power. Check this if you do both these tests and only one wire has power with key on or off then you need to make sure that the key switch is sending power to the solenoid. Do this by checking the smaller wire with key off. It should not have power and then with key on it should have power. If this is good and test one is bad then the relay is bad. Note This is not true for the larger realy that sits furthest foward on the engine. The bigger one. This test will not work for it but it controls your intake heater. On another note: This is a timed circut and will "kick out" after about 1-2 minutes. In otherwords it does not stay on all the time that key switch is on it will for for about 1-2 minutes then shut off! Next would be your injectors are getting weak or bad and even your HPOP could be getting weak. or glow plugs in engine are out, In otherwords there are alot of possibilities causing your problems If you are getting a misfire code for your injectors then you may have some weak or inop injectors. Any way this will give you a pretty easy test for the most common failure which is the Glow plug relay. About 35-40 bucks at your local auto parts house.

hi themulks
dave here

if you have a rad cap open it and check your coolant level. if it is low fill the rad and leave cap off while you then put the recovery resorvoir at the proper cold level. Move your way along to the thermostat and look for a screw and nut at the top of the housing. If there is one then this is the highest point of the coolant in your vehicle and you will bleed it by opening this hole and running your engine until only coolant flows from the exposed hole. Do not remove the screw just turn it until the hole in the side is revealed. I basically almost remove the screw (till it kind of wobbles) and then turn it back in til it stable (like 1 turn). Be sure that the coolant is flowing without bubbles(air) and not just kinda trickling with short pauses.
If the housing for the thernostat is lower than the rad cap then you bleed it through the rad. Wait for the thernostat to open and the level to go down and then refill it and watch to see no more bubbles (air) escaping. Once the vehicle gets hot you may have to wait for the engine to cool(ie) turn it off for a while and redo it. Also if you are using the thermostat bleed hole be sure to put the rad cap back on before you start the bleed process and keep your eye on the coolant resorvoir adding coolant as needed so you dont **** more air into the engine.

P0344 = cam position sensor error
P0603 = Internal control module keep alive memory error.
P1670 = communication error between PCM and IDM
P0562 = system voltage low

My guess is you probably have some wiring issues but it's hard to tell exactly where.

F-350 turbo-diesel hard starting


Imagine the white smoke is unburnt diesel. Anybody standing in the middle of it will be able to tell you soon enough.

Most likely culprit is that one or two of the glow plugs aren't getting hot enough. Usually just that the plugs need replacing, but worth checking first that the busbar which runs between them all is getting +12V at the appropriate stage of the process.
