hello all I have bought a 97 ls integra with a ls/vtec and I'm having an issue already. when I bought the car it had been stripped of the a/c p/s exhaust and both o2 sensors, but it ran so i drove it home without a problem since then I have put the p/s and a/c back on the car and a new exhaust system I'm using dc headers for a civic si connected to a magnaflow cat for a gsr and a extended 2dr exhaust system from topspeed pro one. all of witch worked really well together I was just lacking the 2 o2 sensors..... $200 later I have the sensors put them on and the car ran like a frickin champ!!! for a single key cycle that is. after shutting the car off I let it sit for a couple hours went out to restart and it had a hard time starting after it was runing i noticed what felt like a misfire and sure enough the check engine lite came on. i thought it may have been bad gas since it had been sitting for just about 2 years so I used a gas treat ment and filled the take back up and ...no fix. after that I let it sit for a lil bit and then pulled the spark plugs and to my suprise there was colant in cylinder 2-3. so I need a new headgasket but I have no clue witch one to get....
Thanks for your help

 

Oem b16 or b18c1... Do a compression check too

 

It probably didn't like running without O2 sensors. Make sure you have a good tune or you could blow the new gasket too.
