can i re-torque stock head bolts - Page 3

A retorque isn't going to fix any problems... If you've already got problems it is a band-aid at best. If you've got no problems and it works, you'll never know.

Do know that with a retorque there is always the possibility of making a problem worse or of creating a problem where there wasn't one. You can compromise the head gasket by retorquing... generally this is caused by backing off the bolts too far or from the metal jackets in the head gasket having gotten brittle and now cracking opening pathways for erosion.

Well it seems i may have been a bit premature in announcing that retorquing the headbolts didnt work for me.... Have done 300+k's in the car since often in heavy traffic without any movement from the heater guage or the need to put the heating on.

I did pop in to see Paden at Unique automotive in villawood as i was concerned the HG did need doing but by the time i got there it seemed most of the air was out of the system. He suggested that the way i put the coolant in wouldve created a huge airlock in the heater matrix and that is what i think was causing the airbubbles under the rad cap. Air bubbles seem to have stopped now.

So all is looking good.
