Have you calibrated your torque wrench recently ?

Most read a little light.

 

Undo and retorque the nuts one at a time in the correct order but do them up to 50 lb/ft.

did you check that the head wasnt warped before replacing it

No i have nt its a bit old alright, is it safe to undo and retorque with the system full of water

we've had this a few times copper gaskets always did it on us even with a head skim..

We use the composite ones now...

Normally it goes after a while

Would you loosing off one head nut at a time and then re torque?? in the correct order

[lrostoke]

your supposed to do that after the first heat cycle anyway.

Get engine upto temp after fitting, allow it to cool down.

Then retorque head..back each nut off a touch then retorque..in correct order

Copper cylinder heads are doing this. Rover issued a note to fit them 'wet' (clean them with oil) at a certain point..

Start up the engine and warm it up just a little bit before filling up with water.

Remember to cool down the engine before re-torqueing or you'll end up with a snapped stud (not that they dont snap even when doing correctly..)
