the beater DourFour needed a head gasket on its 250k D15b7. so i did that today and threw on a fresher B7 head that came off my hatch that had around 90k. Im SURE this head is fine. I used a z6 gasket i had and i kept the IM in the car and just unbolted it to swap the heads.

DONE.

the bitch is gushing coolant between the head and the IM in the left corner where it flows threw the mani!!!???

not only that..its reving as if the ignition is fucked up. im useing z6 msd wires cuz i tore a wire when removing the old head. if this is the cause of the hesitating reving please let me know. its choppy in the begining but get it up high and it sings as clear as a bird which gets me to think its ignition and not my timing.

i took the IM off the head and checked that area for a clogg cuz you hear it hissing real bad when i ran it... NOTHING, clear as a ************..
what could be causing this??? HELP!
this is my daily beater while i work on my hatch... i gotta get to my classes tomorrow... i shouldn't have to have down time with this POS...

as in the headgasket?? thats almost impossible cuz the end is sticking out on the right corner and there is writing on it.. there was only writing on the correct side up. the holes are blocked off on the left side of the gasket, i checked the other head i took off and the holes in the head are on the right side... which means the headgasket is on right...

i wanna know every possible factor that can cause this before i go doin this all over again tonight for nothing, so id appreciate a bit of explaination with your suggestions, or atleast be more specific

 

Are you sure the new gaskets you're using headgasket/intake mani gasket are not covering a coolant passage which of course would build pressure and start leaking one way or another.

Check out the gasket and make sure it's the exact same one as the old one you used.

 

Oh did you make sure the surface you put the gaskets on was clean as well if they werent it can lead to another few hours of expletives

 

i got 4 gaskets total layin around from 2 z6's and 2 b7's iev had. im looking right now at the one off the car originally and an identical z6 similar to the z6 one i had just put in... there like identical twin brother and sister, ones metal and the others composite...everything matches, i dont get it...

 

I'm not sure if the z6 is the same as the one for the b7.. probably is... but.. check the new one you put on there is the same as the one that worked before and wasn't causing you problems

did you connect the hoses right?

yes, as i said the leak is between the IM and the head, not the head and the block... so a greasy sealing area on a headgasket wouldnt cause such a leak.

thanks anyway

yea i know for a fact thats right, i only removed 2. the one coming from the rad to the front of the head and the one coming from the firewall to the side of the head...

thats what i just did, and to be positive is what i wanna avoid doing cuz that means doing it all over... i got t-5hrs till class

 

I wasn't the one that mentioned a greasy sealing area... I was talking about the ports on the head matching the ports on the intake manifold. Make sure that the gasket allows for coolant to pass where it's supposed to..

of course not having a flat and clean head/intake manifold surfaces might cause leaks as well

 

well would anyone happen to know if the MSD wires are causing the hesitation? in other words will MSD ignition wires specified for a SOHC VTEC 1.6 work on a D15b7 correctly or no and thats y its running like it is??? im getting some cheapy autozone wires tomorrow morning.. i just needed to throw a set on real quick to make sure everything works... (guess not....)

yea i know, n8byte did, not you lol

ill check again but im pretty sure since theyre both b7 motors that they should be the same.... if not then ill swap mani's with the one i had on that particular head back when it ran my hatch

 

The hesitation is most likely timing related...timing might be retarded.. or you had the timing slightly advanced prior... does the idle fluctuate?

slightly yes, but only after it heats up it would drop in idle pretty low.. i advanced the timing as much as possible.. i figured the idleing was cause of the loss in coolant... but it wasnt fluctuating like how i know your thinking. It changed slowly but slightly noticeably...

also keep in mind, it cuts up and hesitates when giving gas but when higher-high rpm's is reached its clear as can be. I remember a bad set of wires did that to me before... only i KNOW these are good cuz i boughtem and used them for like 2 days on my hatch...
