d15b7 leaking antifreeze from the back of block, somewhere???
okay here we go, i just put my 95 civic coupe up on ramps to take off my stock header and oil pan and all to put my new turbo kit on, well after i ran the oil feed line a few minutes later i saw coolant dripping down the back of the block but it doesnt leak when it isnt on ramps, i checked all the hoses and and couldnt find anything but it looked like it was running off of this on the back of the block. here is a pic i found of it, i circled the part in red. can someone please tell me what this is
any thoughts and help would be very appriciated.

The box you circled is an oil water seperater/ pcv box. Coolant doesn't run through there. Could be head gasket, seals on the water pipe, or coolant hoses coming off the water pipe.

if it were the head gasket i would know it, it would be coming out of the exhaust. so there is no use in me doing a compression test

Do the compression test. Sometimes a head gasket failure isn't just between the cylinder walls on the block, sometimes it is an un-level deck/head, so it will still be useful to run the test.. don't ask for advice, then sit there and tell people to fuck off. you stubborn piece of shit. The pcv box is irrelevant in your quest. there are like 6 coolant lines"
-upper rad hose
-lower rad hose
-from block to heater core
-from heater core to block
-from block to hot side of intake manifold sensor
-from cold side of intake manifold sensor to block
other than that, check the o-rings on the water pipe, and replace the water pump and the seal. clean the mating surface well. Might as well run a pressure test on the radiator itself as well, rent the kit from advance. push the pressure up to 20/25 psi and look for leaks on a level surface. if you need help, pm me, but if you choose to ignore my advice, don't be a stupid ignorant piece of shit and tell me. I don't care.
Good luck.
