Question about 1990 Honda Civic
Hi, I have a way to test for a blown head gasket. Since you have good compression, yours would have to be small. Recommend you park on an incline, remove the radiator cap, set the heater on high, start the car and let it warm up until there is flow in the radiator. Fill the radiator and keep it full while the engine continues to run. Look for any bleed ports the system may have either in the hoses or at the attach point housings. Crack any bleeders open to allow any air out. Top off the radiator all the way to the neck and make sure there are no bubbles coming up. Bubbles coming out the radiator are an indication of a blown head gasket.
Please let me know if you have questions, and thanks for using FixYa.
