i just recently bought a 1994 Civic Dx hatch with a blown head gasket ! for a very good price!! I changed head gasket of which very obvious was bad! around the cyl sleeves it was caked with burn oil and coolant! and the gasket was broken thru any, how i got all the gaskets changed and all put together nothing broken or extra, i have to adjust the timing its running rough right now!! i think i have wires out of the 1342 order! but i what am asking why is the radiator overflowing!! the car its not overheating! rad fan comes on! temp gauge dont get to the hot range at all! i hear bubbles in the radiator! and it comes come out the rad cap! could it be that rad is clogged? please if any one has any tips or comments!!! as far as the car has 200.000 on the clock, but i dont think its the original engine the pistons are clean as a wistle, there was some build up on the valves of which got cleaned up, but i just dont understand why the coolant backs out!! car was smoking pretty bad! before head gasket! now its clean! nothing coming out the muffler like before! you could see oil and coolant! any comments or suggestion are greatly appreciated thanks!!!!
