1ggte head studs.

[mjrstar]

are these re-usable, i'm building a fresh engine (without a manual) and hav not been able to find out weather these are a single use or re-usable. the torque settings do not state 'torque to yield' which leads be to believe i can re-use them.
Does anyone have the manual and cold check this for me. failing this the 4agze manual probably states the same process...
Thanks

Well neither of those list the head bolts as non reusable so hopefully thats enough for you.

[Mr Revhead]

are they torque to "x" setting or are they torque then 90 + 90

all toyota bolts that are torqued by degrees are plastic region

P.s. fingers crossed you can read japanese
This is out of the 1ggte manual

[mjrstar]

um no i don't have the best understanding of japanese....... haha.
seriously though thanks for the info. i think i'll just run a tap down the holes and reuse them.

So don't reuse them.

i dont think you can reuse them is they are strech bolts (have 90 degree rotation) when we did the head on mine we had to replace them and the my mates at the workshop checked with toyota and they told us to replace them.

[mjrstar]

it appears int the manuals above that the 4age are torque to yield and the 1g is a straight torque. i think the ultimate would be to run head studs instead of the bolts.

[Mr Revhead]

can you read the japanese?
if so, what does it say?
if not.... maybe it says otherwise.

[spencer]

my 1gge spec page says just straight torque it up to 650kg-cm which is what that jappa manual is saying same as 1ge aswell

[Mr Revhead]

sweeet

i cant read japanese...
