Re-Torque Head after rebuild?
 

93 1.6 Forged internals with ARP head studs

Quick question. Once I have built the engine and its up and running will the head need to be re-torqued at any time?
Cheers

The instructions say to do it, but I don't know anyone who has ever bothered to. :giggle:

Did you use stock head bolts or ARP head studs?

ARP head studs......

Well what I do with ARP head studs, is 3 step torque to spec, then loosen about 1/2 turn, then 3 step to spec, loosen, then a last 3 step to spec..

This way any movement of the block/styd/nut is made before fluids are added.

It pulls the stud thread into the block thread, and "mates" the nut with the stud.

Thanks. Would you do this when using a cometic head gasket?

Barry

Any and all head gaskets.

But if the engine has been run and has fluids (oil/water) DO NOT use this method

Getting any fluid between a gasket and deck surface is not good.

Cheers, the engine is not built yet, the head is ready and I should get the block back from the engine builder this week.

I take it when using this method there will be no requirement to re-torque the head once the engine (forged internals) has been run in?

many thanks for your advice....

Barry

No, Thats what I do when I build an engine and send it out the door.

Have not had one come back for a blown HG.

Thanks Dale, I will use that method. Keep doing the 'How to's', they are are great source of information!!
Cheers.......:cool:
