i have a d16y8. It was overheated before i got the car. i changed the hg and now it runs like ****. The idle is crazy and when its cold it gets coolant into the combustion chamber. I know this because when its cold it burn coolant but once warm it stops. I think the head is warped but i didnt check when i had the head off (dumb move). i used the same head bolts and im thinking about buying new head bolts and i hope this will help. I guess my ? is will the new bolts help??

 

doubt the bolts will do anything. double check your head and block for warpage.

 

ya i just didnt want to take the head back off but i guess ill need to. What about reusing the head gasket.

 

you can reuse a head gasket if its not old...i don't recommend it but you can. Get studs, don't get bolts, head bolts are ****.

 

maybe your problem was the headgasket???? and resuing the headgasket is just as dumb as resuing the same headstuds

 

this is the second head gasket i put on it because i thought it was the gasket but still same issue. i think ill go to honda today and get some head bolts.

 

Your head is more then likely warped. Get a straight edge and check the surface of the head for warpage and minus well check the block deck once you've removed the head. You can reuse one of the newer head gaskets, but make sure you use some copper spray. I'm assuming you're re-torque your head studs to factory specs?

 

well just got back from honda and got 10 new head bolts. If the head is slightly warped will new bolts help any???

 

i said no

 

i really dont want to take the head off again since i have done it twice in like a month. i got the bolts since iv always heard head bolts are not good reused. Anyone got a b18 ls they wanna sell lol

 

As quoted, no it will not help. You have a better chance of getting the head resurfaced & using the old head studs. But since you have new studs, use those.

I'm 99% sure it's your head. More then often an aluminum head will warp when the engine overheats.

 

do this: get the head resurfaced, get a new headgasket and use your new headstuds...make sure you torque the headstuds in the right pattern and correct amount of torque...this should minimize most of your probelms

 

thanks fellas. When i bought the car and removed the valve cover it was BLACK. I made the rookie mistake of not checking the surface when i did this the first time.( live and learn) Ill be checking it in about 2 weeks so fingers crossed!!

 

i have a question related to this. i just put a d16y7 block with a d16y8 head, head is from my car block is from another. i checked the head for warpege b4 putting it together head was good. ran good for a day then the head gasket blew. just took the head off again and checked the block, don't now if it's good or bad. need to know if anyone know's what a safe deck tolorence is? need some help bad
