well, i changed headgasket bought a crv headgasket. I think that when i had the motor rebuilt to 84mm they used a b18b1 and enlarged the the cylinder holes. The car with the old hg would send my coolant into the overflow tank but wouldn't return. I had to fill my radiator but its also cause the water in the overflow didn't go back to the radiator. I also was having high pressure in the radiator and my need was closeto H even with the fan running all the time(made a switch). With the new gasket the water doesn't over flow to the tank. I haven't checked my oil to see if its milky brown. I still have high pressure in the radiator but i think its because of the 11:1 pistons. I went ahead and order a fluidyne radiator which should be here thurs. I already had to fix my radiator with jb weld twice. Thanks for your info. Any more comments is welcomed on my engine problems.
