    Stanadyne Performance formula

    I installed a Monitor KHW demand water heater in 1993. It burns kerosene which is stored outside. The water heater was discontinued by Monitor a year or two after I bought it. Replacement parts other than the nozzle and electrodes are unobtainium. It's a complex thing and even though I'm...

    Should remote power mirrors work when the key is off?

    Should remote power mirrors work when the key is off? 1993 F250 XLT. Are these supposed to be powered all the time, even when parked?

    Loud rattle

    The saga continues. The current problem is a loud rattle that goes away when the engine is under load. The transmission shifts fine - no more flashing OD light. Around town the rattle is quite loud but accelerating quiets the motor. Sometimes the rattle starts and stops as if it's a loose...

    Removed cluster now gauges are off

    1993 F250 with the automatic. While checking for electrical issues I removed the instrument cluster. I was careful handling it. I found no issues and reinstalled it. Now the fuel, voltage, oil pressure, and temperature gauges are all off. Most read very low, the fuel gauge reads 3/4 on either...

    Codes 43 63

    The rebuilt transmission with 4,000 miles on it continues to get worse. The OD light will start flashing within 2 miles of starting. The transmission hunts between 2-3 a lot now - it used to just hunt around 42mph but now it hunts at a wider ranger of speeds. I've gone over every conceivable...

    Front speakers out out. New radio gets hot

    I'm currently chasing down a flashing OD light and electrical issues. I've gone through 3 replacement radios this year on top of the flashing OD light. Something is screwy.... 1) Both front speakers (in the door) ohm out open circuits. Both speakers have a good positive feed but no ground. Both...

    Coolant leak

    After weeks of zero leaks on the garage floor (fixed ATF, diesel, and motor oil leaks) a large dog sized *** puddle presented itself this morning. It seems to be coming from the the passenger side toward the rear of the motor but I can't see where it's coming from. The truck (1993 280K miles) is...

    TCM R&R

    In a 1993 F250 with the 7.3 IDI and E4OD the TCM is located below and to the right of the master cylinder. The TCM is removed and replaced by pulling/pushing into the firewall. There is no reason to remove the kick panel inside the cab. The inner fender has to be moved but not necessarily...

    Rebuilt E4OD 800 miles ago now having problems

    A local shop, member of ATRA installed a rebuilt E4OD last fall. I bought the 4 year warranty transmission. Recently the first drive after warming up will have some barely noticeable shuttering up shifts which lights the shifter LED and starts the limp home mode with harsh upshifts. If I shut...

    Cleaning out clogged AC drain.

    Drove the truck Saturday (5 days ago) and it's still leaving a puddle of water on the garage floor. The AC works great but I'd like to get the drain to flow faster. It comes out near the passenger's feet under the truck (outside, no leaks inside yet). Thanks!

    Exhaust manifold gasket question

    I believe I'm being cheated at a local chain for a state inspection. The same shop has inspected all my vehicles for years - I left off two vehicles last week for the required annual Maine inspection. The shop claims the exhaust manifold gaskets are leaking and need to be replaced in order to...

    Leaks when it rains

    1993 regular cab - the drips form on the plastic trim that frames the windshield directly above the turn signal stalk. First I suspected the clearance lights and replaced the foam gaskets and the clearance lights with what looks to be original equipment. I added LED lights and it looks great...

    Number 8 keeps dripping

    The return line or plastic housing has developed a leak that o-rings and new lines have not corrected. The engine starts fine, I don't like the diesel fuel smell and small puddle on the garage floor. I have not replaced the flimsy looking black plastic cap (weren't the original caps metallic?)...

    Driver's door suddenly hard to close right

    There's no noticeable play in the hinge pins when I checked and the striker pin looks OK - there's a very thin plastic covering over the pin that is torn but I can't imagine that would be the cause. I've lubed the mechanism and nothing looks broken. Getting the door closed properly requires a...

    Where is the iron sludge in the rear axle coming from?

    It's a 4.11 limited slip full floating axle with 280K miles. I'm finding iron sludge attaching itself to the magnet in the fill plug and on the speed sensor at the top of the differential. This eventually causes the transmission to go into the limp mode until I clean the sensor (shutting off the...

    Re-power with crate?

    I bought the truck new in 1993 - it's still in good condition but has 280,000 miles on it. The transmission, last rebuilt in 2004 is going into limp mode and last ATF change there was a fair amount of metal in the pan. The motor has never been apart and it's naturally aspired. A new truck is...

    E4OD cooler line OD

    I added 2 transmission coolers 15 years ago to the 1993 7.3 IDI pickup. I had to splice into the steel cooler lines to add the auxiliary coolers. Where the rubber hose connects to the factory steel lines has been an issue - the small stainless steel hose clamps are of poor quality and loosen. I...

    Issues come in bunches

    The fuel selector valve went bad so I farmed out the repair to a good shop. Replacing the fuel tank valve weakened the fuel lines where they attach to the top of the tank. A new sender, some fuel line repairs and the truck had air in fuel symptoms. The shop stood by their work and made it right...

    Air in fuel system after selector valve replacement

    A local shop replaced the fuel selector valve, dropped both tanks and replaced the fuel (tube or sock) in each tank. When I picked the truck up it started hard, surged and bucked. The fuel filter/water separator was wet on the bottom so I replaced that and cleaned the fittings and schrader valve...

    Fuel tank switchover problem

    The truck ran fine on the front tank but when I switched over to the rear tank at 80mph the motor started bucking and the fuel filter light came on. Switched back to the front tank and the motor ran fine again. I did use the rear tank at lower speeds and it seemed to work fine. I don't think...

    quick question. steering wheel

    I replaced the steering shaft and now the steering wheel is at the 2:00 position on a straight road. Rather than going through all the grief at the steering box (removing and resetting the splined connection) Can I pull the steering wheel and center it that way? I can't remember of the steering...

    Rotor and pad suggestions to improve braking

    My '93 F-250 has always had poor braking since new. The rear drums probably do 10% of the work, the front disks could be better. The current disks are gouged. On another vehicle I tried slotted and drilled rotors and was very happy. The quality matters too - some Chinese rotors rust overnight...

    Black smoke under moderate acceleration

    At 270K miles I had the injectors and injection pump replaced by a local shop. The truck used to smoke only at higher elevations - around 8,000' and higher. Now the truck smokes at speeds over 40 when I accelerate. I towed a 3 ton travel trailer a few days ago and it smoked more - a grade made...

    DB Starters

    I've been throwing parts and money at hard starting problems in my '93 7.3IDI that I bought new 270K miles ago. New batteries, new injector pump, new return lines, new glow plugs but the truck continued to start hard despite being kept in a 45F degree heated garage. For $95 a DB starter changed...

    What size hose from auxillary trans cooler to steel factory line?

    It's a 1993 F-250. I have had lots of trouble getting a good seal where the rubber line attaches between the after market auxiliary cooler to the steel cooler lines - plus the hose clamps I can find are really flimsy and strip out easily. Anyone know the size of the stock steel cooler lines...
