i just replaced my head gasket but can anyone tell me what the pressure should be on the head bolts ? and there is a plug going in to the back side of my thottle body that is broke any ideas? please help and thank you

 

first off you need to tell which engine you have in it.
as for the plug, no idea

 

i have a d15b

 

do you have a tourqe wrench

 

like a jdm vtec d15b? or did you leave out a number by chance?

by the sounds of it you did not torque the head bolts in sequence or to spec so it sounds like you'll be pulling the head and replacing the gasket again.

 

i'd recommend finding some directions,
either find access to a helms manual (ideal)
or at the very least there must be a writeup on the internet you can follow.

when I was first starting out wrenching, I didn't know what I was doing,
so I followed directions as best as possible. doing it on your own when you're not sure is a good way to get into trouble!
