When I relieve the hydraulic pressure,usually by pulling back on the loader control lever, it helps tremendously. I tested the wires that plug into the solenoid on the main...

    .Water and oil mixing

    I assume it must be something happening when the engine gets hot. if I choose to use a sealer, should I use a radiator sealer or a block sealer? I asked that question because I'm not sure how block sealer works ugh with the o'rings at the bottom of the cylinder sleeves.

    .Water and oil mixing

    After running the engine for two hours I checked the oil and we have water in the oil again. So today I did a pressure check on the coolant system.
