Okay, so I recently just did a head swap on my d16y7. I threw a y8 head from a 00' civic onto my 98' civic hatch. I did the head swap everything went smoothly with the head gasket replacement and then torquing everything down to spec. I started with 14 ft-lbs then 36, and 49 twice just as the service manual says. I did not even get to start the car yet. As soon as I filled it up with fluids I went inside to grab a drink came back out and noticed that the coolant was all over the ground. I know I am gonna get a whole lot of shit for not doing it correctly and trying to get by with a half-ass job, so please spare me the embarrassment. I just need help. I'd not clean the old intake manifold gasket off and I did not buy a new one. I know that the y7 Intake Manifold has a coolant hole that runs to the thermo housing. With that being said I bolted the intake manifold directly up to the head with no gasket... Could this be the cause of why coolant was rushing straight out of that area? or is it more likely that the head was warped when I bought it and it needs to be resurfaced? I even tried to tighten the IM bolts down as tight as possible and it didn't slow the leak. I couldn't pinpoint the leak but I could see a stream of coolant after filling it up coming from either the corner of where the head meets the deck or that coolant hole that is on the IM. My only indication that it may be warped is I wasn't sure if coolant would run through the thermo housing and to the IM without starting the car and just filling it up. Any help is appreciated.
