Ok, since my last thread.. I was going to just get my head resurfaced b/c of a blown head gasket.. now i'm thinking of just rebuilding the whole thing.

What should I tell the machine shop to replace?

so far:
New Valve Stem Seals
Valve Stem Springs

and i dont know after that.. anything else? btw, this is just a DD car

jyacoba2009

valve stem seals
Valve stems
Valve seats
Valve spring retainers

anything else you guys could add?

why springs? do you beat on the car? how many miles? i would just get the head inspected, resurfaces, valve job, new stem seals and call it a day.

jyacoba2009

nah its just my DD.. its an auto [thank god] or else i'd be in the powerband during my whole drive

but idk, i was just looking in my haynes manual and was adding things on what to replace.. i have no idea what to replace, so i thought of just replacing all those things

maybe a pnp?
seals, seats, stems, not sure if you need retainers, if you want them go for it.

jyacoba2009

whats a pnp?

projectTeG

port and polish, dude just take it to the machine shop and tell them to refresh it for you. theres no need to replace the springs and valves, your not beating on it...your fine.

port and polish would be a complete waste for a DD auto IMO

jyacoba2009

yea thats true, so thats what pnp meant.. and also a 3 angle job isnt even needed too. i just want to replace stuff that probably got damaged or i should just replace for the hell of it since my head gasket blew.

btw.. since i gotta take off the intake/exhaust manifolds, do i have to buy the gaskets for them 2?

just take it to them and ask them to spec the head they will check the head for warp and deck it if it needs it replace the valve stem seals, have them check the valve guides and replace any that are out of spec

jyacoba2009

yea i know that, but i didnt want to go to them and they say i need this and that when i dont.. so im just lookin for some insight of what to expect or what not to

but thanks for the input, everything is definitely helping out

the decking needs to be checked and any reputable shop will only mill it if the head is out of spec. If you have over 100k on the head and are going to have it worked on replace all the valve steem seals period you have the head off and its easy and cheep to do. So if its going in for the deck to be checked again a good shop will only replace things that are out of spec so have them check all the valves and guides and replace only what is out of spec. I have sent heads in that they have replaced 3 valves no guides and replace all the seals. and others that have only need to be milled to true out the deck. It can be a real crap shoot as to what you might need. Ask some of the service stations around you as to where they send out there work to be done, the dealer can be a great place to find good mechine shops most dealers send these things out to have any work done to the head
good luck

Ohh totaly overread that its a auto... Hahah yea it would basicly be a complete waste

jyacoba2009

oh btw.. i dont know if i asked this or not

since i'll be taking off the intake/exhaust manifolds.. do i buy new gaskets for those too?

93egSLEEPER

yea replace both.exhaust gaskets are "crush" type and your supposed to replace them each time you take pressure off them. do the intake one as well... dont wanna risk a vaccuum leak from something so simple

jyacoba2009

yep, true that. thank you =]

about how much does it costs to rebuild a head for 96 ex , 3 angle valve job, and a port n polish. just getting the idea of how much because my head is bad

jyacoba2009

about 350 or even more, 350 is what my local machine shop quoted me
