    Bolt on exhaust system recommendations

    I currently have a Walker stock exhaust - very small diameter. No turbo nor any plans for one. I like the Hypermax 3.5" as it appears to follow the stock installation - over the axle and exiting on the drinker's side of the truck $795. Hypermax isn't answering their phone or returning messages...

    Fleetguard coolant test

    Haven't done this test for a while... I watched a Fleetguard video on YouTube and if I understand correctly the Moly & Nitrate readings intersect in the green zone called "service" DCA additive is still required. Years ago I overdosed the coolant and maybe coincidentally the water pump started...

    Fumoto 1/2 - 20 source

    It appears that the proper size drain valve is out of stock - one EBay seller with a 92 positive rating does offer one - that's a red flag. Does anyone have a recent source? At this stage the drain plug is the only leak I have and I'd be just as happy with a quality standard drain plug with...

    Passenger seat belt anchor to floor problem

    1993 regular cab has been in the seat cover shop for 3 weeks. The owner does good work and can't find any good employees so there's a long wait... He starts removing the stock bench seat today and calls me telling me that the passenger seat belt anchor bolt can't be removed despite soaking it...

    Seat pad

    1993 F250, real good condition. I have a little extra money and have my eyes on an LMC Original Style Velour reupholstery kit. It's almost $600. The original seat sags on the driver's side and the fabric is torn where I slide in and out. I hear a foam pad for the seat would make a nice repair...

    ABS light comes on

    1993 F250 7.3 IDI E4OD 280,000 miles... ABS Light remains off until a moderate braking event - then light remains illuminated until the engine is shut off. Red brake warning light sometimes lights simultaneously. Truck always brakes as well as it ever did when new. ABS on the rear axle never...

    Front differential drip

    State safety inspection coming up this week and anticipating 2 drops per week from the front differential housing might be a "safety" issue in Maine that could cause the truck to fail its annual inspection. I cleaned up the housing and the leak appears to be coming from the bolt at the 4:00...

    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...
