    Clutch won't disengage

    For some time, my clutch pedal would not immediately return to "pedal-up" position, mainly when shifting out of gear when coming to a stop. Pedal would come to about 75% off the floor and then pop to 100% off the floor after a few seconds. I figured the problem was mechanical in the pedal...

    Leaking Coolant

    List: After some years of (nearly) trouble-free performance, which is in itself remarkable for an aged vehicle @ 245K miles, my '88 F-350 began leaking coolant yesterday. I'm getting about 5 good drips per second, some from the joint between the vibration damper and the oil pan but mostly...

    Where can I acquire one of these tools? Is this the same as an OTC 7269? A Lisle 28000? And what tool do I need for the front axle spindle nuts? The manual was unclear (or I was looking in the wrong place). Thanks and regards,

    How does PEX hold up in diesel fuel?

    I need to fix/replace the fuel filler to my rear tank. I have searched and seen info on the fuel filler mod, but I think I'd like to stick with the stock pipe-in-pipe configuration so the tank connection(s) don't need to be changed. My inner pipe (which appears to be for fuel into tank)...
