so now that im finally putting some miles on the 323 ive ran into an issue. first, the car has brand new hoses, new water pump, a fresh radiator flush, oil change, etc. im not running a thermostat. it doesnt smoke except on initial start up, but quits shortly after. it starts to get hot about 20+ minutes of driving/idling. i dont think its the headgasket because it doesnt smoke. but i do slowly lose coolant after a few days also. i thought maybe it could be a bottom end problem, like main bearings going bad. any help would be appreciated. thanks!
its a 1988 mazda 323, 1.6L 8 valve SOHC B6.
