Problems and pictures.
Ok, so I recently traded an 03 ranger for a 1999 F350 with the 7.3 The tag on the engine says it was produced 03/dec/98, so I assume its a 99.5-03 version of the engine? Its a dually, with the automatic, it has 178K miles on it. New water pump, tensioner, power steering pump, ect..
The issues im having.
1. Takes a while to start sometimes. If I let the truck sit for a couple days, when I come back out to start it, I have to crank it 3 times for about 10-15 secs a try to get it to start. Once the truck has run for a bit and warmed up, it fires right up. If it sits a day, and its not a cold day, it will start after about 10-15 secs of cranking. Yes, it runs rough while cold, however once it warms up, its nice and smooth with plenty of power.. Pulled apart a 20K lb tow strap with ease.. (Sigh, one more thing to go buy again, guess I'll remove the stump the right way this time...)
If its cold (Under 30 degrees.), it has to be plugged in. Yes I know some of the glowplugs are bad. I followed the instructions I found here and tested em. Plus the big whitish grey cloud in the mornings gives it away. 10K+ resistance = not good. I plan on replacing thoes shortly (When I take everything else apart to do the turbo.
2. Please take a look at the pic, and let me know if you have any ideas as to what might cause the turbo impeller to look like this. I found a new impeller on ebay for $35. Other than the impeller, am I going to need anything else when I take the turbo apart? Can the gaskets/o-rings be reused as long as they are intact and in good shape? The casing for the turbo looks pretty new. Also, any advice on where the missing peices might be, or a good way to REMOVE them from the intake system so they never get sucked through the engine? Also, how can you tell when the "soft" hoses for the turbo system need to be replaced, and is there an inexpensive alternative? (Anyone have a spare set lying around after upgrading to an expensive set?)
3. I've read a bit on the forums about injector buzz tests. Do you need a special tool or a scanner to do that, or can that be done somehow without a scan tool?
4. Im not looking to build a race truck out of this, and I havent finished browsing the forums, but if im taking all this stuff apart, does anyone have any advice for things that can be done to improve fuel mileage while I have everything apart? Currently, I think im getting about 18mpg.
5. I am thinking of putting in a 2000w power inverter, and running 0/0 gauge power wire. The wire I have is almost like welding cable, flexible and very fine strands, you can cut it with scissors if you go slow. Would it be a good idea or even worth it to replace any existing battery cables with the stuff as well?
I appreciate the help guys. Thanks.
