thank you guys for the suggestions.
@autophile i will try and compare it with a similar car.
@spectra r u really sure that its a sign of a engine failure because my car does not eat up oil i do change it regularly as well.
@testdriver a mechanic also asked me to check for this thermostat valve but i didnt give too much attention to it cause i dont realy know exactly what it is. also i have got the radiator cleaned thoroughly twice no effect and obviously the coolent level is fine as well although having said that i always fill up the rardiator with a mixute of cooolant and water and not just purely coolent but that should not make any difference should it for civic 95?
@timelessfahad by heating up i mean really heating up like going to the red sign and all teh coolent and water boiling and trying to get out of the radiator really hot!
