Question about 1996 Geo Prizm
She starts fine, idle is fine, no leaks anywhere, not blowing smoke. 15-20 min later temp guage goes through the roof . I open the radiator cap, oil in the coolant. Is it the head gasket? Can it be something else? I replaced the thermostat about 20,000 miles ago not leaking from waterpump. Is the oil in the coolant hindering the cooling of the engine? I can take the head off and get to the gasget is there anything special I need to know about reassmbly, ie: torque # for head bolts or timing . Thank you for your time. Ben
Head gasket or cracked head. Thats the only way oil can get in the coolant.
Do a compression test on each cylinder to test for crack or leaking gasket.
