ok so im new to this forum and it says introduce yourself lol so um this is me i own a 95 coupe live in the great state of OKLAHOMA love street racing and blowing ppls doors off....with all that said i have a problem: and was courious if i could get some help..............

yo i need some help here i have a 95 civic ex with a b18c1 swap boosted, ive had a continious problem with over heating and pressure building in the coolant resevoir, no coolant in my oil and ive done a gasket change also ive replaced the rad, thermostat, and all rad hoses ive also ran it long enought to get all the air bubbles out .....i thought i had it fixed went out for a drive and again pressure and over heating & bubbling in the resevoir....... HELP PLZ..... ive invested lots of time and $$$ into this project thought it was complete but i cant call it that till i fix this issue..... someone suggested the heater core clogged but idk so any help will be much appreciated!!!

 

are you sure that the cylinder walls arent cracked?
i just learned about this not to long ago. if your not sure if they arent that could be the problem.
have you done a pressure test?

 

better go for their replacement to any good service station, i am sure u would get resolved with the issue of it....

 

Sounds like possibly a flow problem. You should be able to just bypass the heater core to see if thats your problem
