I own a 1989 Honda Accord with 60k miles. The car loses coolant, however I never see anything on the ground and the oil is fine. The car runs same as always and I have had it to 2 shops and pressure test do not show a leak and the car seems to hold the pressure. I have replaced the radiator cap but it did not make a difference. Has anybody experience this type of problem?

 

Check the passenger side floorboard,it could be your heater core leaking.

if the heater core was leaking the pressure test would have failed. he mentioned the pressure test held. how much coolant loss ? is this a lx or lxi? the lx had a base plate that had a problem with leaking into the intake. also could be a head gasket leaking internally into the cumbustion chamber. most pressure test wil lnot show a head gasket leaking the best way is to discon the dist harness and open the rad cap and make sure the coolant is to the top and have some one crank it over and if the coolant starts to bubble or push out i would have to say a head gasket issue. as far as the oil in the coolant is not a honda trait the only time i have seen oil and coolant mix is a cracked head and the 86-89 accord had some issues of cracked heads inder the cam shaft.
