bent valve

[toddnos]

OK so when my timing belt broke it bent an exhaust valve in the #4 cylinder.....it runs like tick tick tick...pop pop pop pop.....i am going to the junkyard today to look for a head on a wrecked accord(wrecked=running when crashed usually)...should i just get a head like the one on my car lx accord....or should i get an EX head..will the ex head/manifold bolt on with no mods? any help is well appreciated!!!

[almostJDM]

you should go EX head if you can find one it bolts right up but if you wanted to use it youll have to wire up the IABS if you use the EX intake mani.

[toddnos]

OK, so everything else will bolt up....i can lock the IABs open until i wire them up....but everything will directly bolt up right? i dont want to go get a head that will require a lot of prep to bolt on....head gasket? which to use?

all f heads and manifolds are directly swappable. they also used the same headgasket. take an EX head (92-93) and manifold, as well as the PT6 ECU

thanks for the advise....my freinds think im opening a can of worms swapping the ex head /mani and ecu/IABs.....

[Leung]

lol i love that saying... "can of worms"

i wish i could find the head off an EX but a DX is better than not having a CB7.

If youre gonna pull the head off the engine sit aside and get you a h23 head. Just seems likea good opportunity for enhancement...your car will love you for it..

i dont have time or money to waste..i pulled an ex head out of a wrecked accord today payed 48 bucks. gonna just slap it in tomorrow.

when we were taking off everything to remove the head, we noticed my o2 sensor has a cut wire...and my radiator has a leak.....more$$$$$ to spend...geez. I really should be replacing the water pump and replacing all the seals too....but this motor is so old i dont know were to draw the line...and i havnt had a car for a week now.

hahaha there in lies where the black hole of the automotive industries rules. Nothing last forever unfortuantly, honda's do die sometimes, see if u can find a good rad in the junker or something, ive found a couple but i never needed them so i left them in the Junkyard haha. all the dizzies however disapear like hotcakes. , just get O2 from junkyard hahah, small enough to fit in pockets lol or just rewire it with some solder. its like $400 to replace Tbelt, waterpump and everything to boot, well thats from my mechanic anyways

[toddnos]

the ordeal is over....for the moment....I found a good ex head at the junkyard, and bought a replacement radiator...still need an O2 sensor though.
The car seems to have a little more power..im still babying it as its the first day ive drivin it since the head swap...BTW i bent all the exhaust valves on my other head when the timing belt let go....anyone know the differences with the EX head, compared to the LX head?

[N9netwoAccord]

EX head comes equipped with a better cam, better intake manifold and better exhaust manifold i beleive

[toddnos]

i only swapped the head...i wonder how much different the cam is..the car feels different.

[blackcb7]

said cam is to be about 8-10 horsepower, not occurate, but around there

[Granite CB7]

^The EX cam is slightly more aggressive, but I'm not sure about the 8-10 hp difference Using the EX cam and both manifolds will yield the best results.
