I just had to pull the head off a jdm d15b today, to replace some bent valves, and I was wondering if the head gasket needed to be replaced. The head gasket was just replaced about a week ago, so i guess my question is whether it will seal ok, or if it needs to be replaced if it has been torqued down. thanks.

 

Junk it, if you want to do it right
those gaskets are compressed sealed.

 

why junk something that anit broken?

i use to always junk it
but after one time when i had to pull a head over 4 times to find out why it was smokeing

i have been saveing and reuseing headgaskets

 

I would replace it. it will seal a lot better.

 

i would junk it, its my experiance that its not good to reuse them...

 

clean it copper spray it and put it back in make sure the mating surfaces are clean to, unless you got HG $$ to burn.

 

Yeah, that was my plan. make sure everything is perfectly clean, copper gasket spray, and then reassemble. seems like that should work out ok. if anyone has any horror stories of reusing head gaskets, post them tho.
