    Brake Pedal to the Floor!

    So...where is the fluid going when you press the pedal. Since the truck is fairly new to you, I'd check for a missing brake pad (or shoe), or maybe even a rotor. I vaguely remember a possible issue with position of the MC piston...If it's not correct, fluid will just recirculate to the MC...

    I'm not much of a fan of engine "additives", but Water Wetter dropped my engine temps significantly.

    How to Desmog an FJ60

    Yes....to the big intake port under the carb. Don't forget to actually install a PVC valve.

    2f oil pump options

    It was a long time ago, when I took mine apart, but I'm pretty sure I reused the original hardware and didn't bother torquing anything.

    2f oil pump options

    I concur with the other guys. Rebuilt the engine at 160k (manifold gasket leak...melted piston) I bought a pump rebuild kit at the time, but the pump measured as new so I left it alone. At 300K+ oil pressure is great and the kit is still in the spares box.

    Move Over SHELL ROTELLA The New FSM Viscosity Chart Sheriff is in Town VALVOLINE 20w50 Full Synthetic

    For anyone who'd like to dig deeper....Check out Jim Comstock's oil test project. Jim is a Norton Motorcycle guru and put a lot of time and effort into this. Yes, ...this is designed to find the best oils for Norton Commando engines, but the flat tappet requirement is the same...

    AC Compressor ID

    Which compressor do I have? TIA I'm asking because this one sounds like it's grinding marbles and the ID tags are unreadable. Doesn't necessarily look like either of those available from Rock Auto.

    '84 A/C leak question

    Don't recharge without adequately evacuating the system. Moisture will react with refrigerants and cause corrosion over time. Moisture will accumulate at the expansion valve, freeze, and can close it off. The increased pressure can damage the compressor.

    Holley fuel pump module for fj60?

    I've been running a powerSurge with no problems so far. I went with the PowerSurge because I DID see a few references to fueling problems (FJ60 + Sniper) when using an inline pump alone, and didn't want to mess with the tank. I'd like to hear from anyone using an inline pump alone on a '60...

    Has anyone tried swapping the V6 motor and 6-speed trans from an FJ Cruiser into an FJ60?

    I lived in L.A. back in the 70's. Smog was horrible. You don't want to go back to that. Oh...and generators will be batteries. Ford F-150?

    Duracool-12A (TM), Envirosafe (TM), RedTek (TM), FrostyCool (TM) AKA Hydrocarbon AC Refrigerants

    Seems to be a little confusion here and there. Remember...Duracool and Envirosafe are hydrocarbon blends and not freons (fluorinated hydrocarbons). Please forgive my redundancy.
