~174k km's on mine. Using a couple tablespoons of coolant per week and can hear bubbles moving through the heater core. The bubbles seem to get particularly bad after a sustained high speed run. Darned if I can find any external leaks. I don't see bubbles in the radiator when running, it's not milkshaking the oil.
Been running a diesel fuel additive with potassium in it, so UOA may not show anything meaningful. Maybe an exhaust sniffer in the radiator outlet.
Current plan is to keep driving it, keep topping up coolant, and wait till it's bad enough to be definitive.
Any other ideas?
What's the current best head and gasket kit for a 1KZTE? Not looking for power, just reliability. Don't have to worry about this again.
