ok guys i just got done turboing my d15b7 , and she has been running great but the other day i was driving it and my hase from my iac broke and i lost my coolant , and she got hot [&:]so i was not to far from home , and i stopped to let her cool down and see why and what i could do . i cut the end of the hose and put it back on the iac but i know i was low on coolant but she was cooled down so i started home again but she got hot again ! i was able to shut her off and coast in to my drive then pushed it to the garage. i added coolant and let her cool then started up and everthing seemed good . now i ran a commpression test on the motor and i got 155psi on 1, and 157psi on 2 ,153psi on 3, and 160psi on 4.i drove her today after about 3 day of taking it easy on her since she got hot , and i got on her a little seemed good but when i got home she was misfiring on number one ? i pulled the plug and i think it might be burning water so i think the headgasket is bad , now i had a civic do this before after i changed a headgasket and found that i did not have it tight and when i retighted it it was ok ,so i tried this but no change . i got new plug wires ,plugs, distributor cap and rotor. still no change , i also changed the fuel filter and a injector , it was clogged from dirty fuel . now when i let it cool it does not misfire but when it warmsup it misfires , do you guys think that it still could be the headgasket , i dont use coolant and i dont see any in the oil , but could it be leaking ? and causing it to foul out the plug? any help would be great, thanks hugh

 

how hot it hot?

you could have done worse than the headgasket. it could have cracked the head its a possibility.
get colder plugs NGK 7's or something like that.

 

well i took the head off and the headgasket was blown . i flat ruled the head and block and all seems fine , as far as a crack i will find out tomarrow when the flow check it then i will put on my 2mm headgasket that i just got ordered tonite and it should be overnited so it should be here by friday so i can be racing by sat
