SVT Torque Specs (Engine rebuild)

[6speeder]

Does anyone know the torque specs for the cylinder head bolts on an SVTf? I'm also looking for the torque specs of the bolts on the connecting rods.

any feedback would be greatly appreciated!
Even if you have experience and have a good estamate! i've been searching all over the internet and have found next to nothing.

Thanks!

in case anyone doing a rebuild is curious i figured it out.

Connecting rod bolts: 26 ft-lbs + 90 degrees turn (stretch torque bolts)

Head bolts: 15lbs sequentially, then torque to 30lbs sequentially, Then + 90 degrees (stretch torque bolts)

How did you figure that out? Are those proper OEM head bolt torque specs that you got from where..?
Just curious because i bought a Comp Orange with blown head gasket and now it's all standing still because i cant find any damn info about the proper cylinder head bolt torque, not in this forum, not on FJ, not anywhere, not even in Mitchell or AllData...

[s0B0Ta]

ok, nothing tells me about my SVT cylinder head OEM bolt torque..
I got the same useless data from my Mitchell software about all ZETEC-E, G, X, U-name it, but no SVT Data.

So, going back to my question, what is the proper cylinder OEM head bolt torque spec?

[BlkNite713]

Lol sorry didnt realize it was blank hahaha 50Nm single sequence

[s0B0Ta]

36 ft lbs only? one guy claims he found the secret; 15 ft lbs sequence, 35 ft lbs sequence and lastly, 90 degrees.
I need rock solid data or i'm not driving my SVT..

[BlkNite713]

No that doesn't sound right. Here is the exact info from the ford technician...


Tighten all bolts in a single sequence
Note: Always install new cylinder head bolts. 50 Nm
Back the bolts off 1/2 turn.
Tighten the bolts in sequence shown to 50 Nm
see note
Note: Rotate all the bolts in a single sequence an additional 180 degrees in two steps of 90 degrees each.


Hope that helps.


Anthony

[s0B0Ta]

hmm, double 90 degrees on these thin bolts? i dunno.. did u or anyone u know actually used this sequence without snapping those black straws?

[BlkNite713]

No, I'm sure that the people on focal have because that's where the information came from. I personally have not though. Check over there on there forums, a lot of good information that sometimes isn't on ours.
