Today was the second attempt at getting my new motor running for more than 30 seconds. Last weeks attempt showed my original starter to be inadequate for the tighter motor. So after replacing it with a new gear-reduction one, we gave it another go this morning. First thing to happen was the oil gauge feed tube snapped off the sending unit at the block, sending about a quart of oil onto the floor. Knowing we had good pressure, we fitted a bolt into the housing and tried again. Started right up, but it had a hard time idling so we adjusted the dual Webers until it was running smoothly. Checked the temperature gauge and it's in the red zone! Shut the motor off. After releasing the pressure through the radiator cap, we opened up the thermostat housing to find the thermostat was wide open. Stuck a meat thermometer in the opened radiator and it read 160 degrees! Now what is going on? Replaced the lost fluid and re-started the engine. Temperature gauge was now just below the red zone and it stayed there...for awhile. Then it started to climb and the meat thermometer started to climb to 170, then 180, 190...so we shut the engine down. /ubbthreads/images/graemlins/confused.gif
The only things I thought of that could be causing this are 1). a weak water pump; 2). crap from the heater core is plugging something in the system; 3). a more efficient radiator and an electric fan might help cool things down.
My plan right now is to flush the entire system and try again. But I'm really wondering what is going on here. Has anyone else ever had this type of problem before?
