91 Camry SV32

[Vince_K_12]

1991 Toyota Camry SV32 4 Cylinder, 2L auto. Pod Filter installed. low 300,000km

Needs to be jacked up at front when filling up radiator to avoid an airlock because radiator is positioned lower then the top of the motor by about 1/2inch.

Uses about a litre to a litre and a half of water within 100km on occasion, not all the time driven, can't find where its coming from, had the radiator flushed out, radiator top tank replaced, new water pump about 6 months ago and also renewed thermostat. If left sitting not used it seems to drain near 3/4 of the radiator within a week. Can't find any signs of leakage, little bit comes out of exhaust but could be condensation. Otherwise totally reliable.
Any Suggestions

Only ideas are that it could be a cracked head or gasket, but want anothers advise before replacing engine.

Thanks
Vince

"If left sitting not used it seems to drain near 3/4 of the radiator within a week"
does it happen WHiLE car is not used (during the sitting period), or it uses that amount AFTER the car is started and driven after it sitting for a week??

If left sitting without being driven, it drains that amout within the week.
