    Question on CDR Valve

    I assumed the CDR valve, was a check valve in one direction. When I took mine off, I can blow in either port, and it is free flowing both directions. This does not sound right. If it is, I don't see the point of the valve. Just use a piece of pipe or hose to go from valley pan to back of the...

    Rear Main Seal Questions

    Ok. Finally pulled tranny to rebuild and fix significant oil leak from rear main. A quart of oil every week. I pulled seal mounting plate off and saw the crankshaft seal surface. What is with that groove?? That can't be as designed. No wonder it was leaking cause that spot is about where the...

    Question about fuel filter housing

    Well my fuel filter heater started leaking bad so it needed fixed asap. I have read that most guys generally remove it and plug the hole and simply eliminate it. Since I am in Florida, I also saw no need for the heater and figured I would do the same. I did not do the typical 1/2 NPT pipe thread...

    What is this pressure sensor for?

    I have been sorting thru and repairing all the things left to make the truck right. On the filter housing is this pressure sensor. What and where does it go to and operate? Since it looks to be a pressure sensor, I am guessing it may hook to the fuel filter warning light on the dash. The light...

    Putting Oil Change into the Tank

    Was just changing the oil in my truck (1994 7.3 IDI NA) and was wondering if there is any harm in just putting the waste oil into the fuel tank. We're talking like 12 quarts plus. I would make sure the tank is full of diesel, about 18 gallons so it would dilute sufficiently. I have a 500 mesh...

    Question regarding E4OD

    Last summer I picked up a non-running 1994 Vin K regular cab 4x4 with an E4OD. The engine is not the turbo version according to the engine block number (7.3 U2U1028595). There was evidence of a turbo since there are firewall scorch marks in the paint on passenger side firewall. Not sure what...

    Question about glow plug controller

    Just a simple question. If I leave the ignition key in the On position where everything in the truck is energized, the glow plugs start to warm up. What if you leave the key in that position for say, a couple of minutes, will you burn up the plugs? Or is the controller smart enough to time...

    Fuel Gauge pegged - where to start looking

    I have a 94 F-250 HD 4x4 Vin K truck with a NA motor. Systematically going thru it and making repairs. Next is the fuel gauge. I have replaced the the dual tank switch on the dash as it was broken. The gauge sits fully pegged on full regardless of which tank it is switched to and I know the...

    Removing Timing Cover

    Hi all, First time posting. Have been following this site awhile and have learned a lot. I picked up a 1994 F-250 HD Vin K regular cab 4x4 at a good price. I have been going thru it systematically fixing all the things that needs to be done. It was a turbo truck but somewhere in the past the...
