Head Bolts Torque Problems

[v6horse 1]

Hi guys ,

I have torqued my head down but after doing the first step with 40 nm instead of doing 60 nm the torque wrench was set to 80 nm , I know after you do the 60nm your meant to turn the bold 90 deg further and then another 90 .

Would you think i should only turn the bolts another 90 deg or leave them on 80 nm of torque .

Thanks

You should always torque a head down according to the specs given. It means the head is equally tightened so as not to distort it. It's also means that the gasket is compressed equally and will create a good seal.

Tip; you should always grease/lube up the bolts and washers before assembly to stop them binding up.

That i understand . I was doing everything by the manual but fucked up with the torque wrench and set it to 80 instead of 60 nm of torque . Sobwould you recomend just tightnng them up another 90 deg instead of the 2 x 90 deg that is said in the guid as im not starting from 60nm but 80 nm of torque . Simple mistake but has it cost me a new set of bults and gasket or can i salvage this is my question ?

I'd start again, bolts should be fine, as they usually stretch on the 90deg turns.

Slacken the bolts in the reverse of the thightening sequence.

I'd go with Pauls recommendation and reverse what you've done and start again. Remember to stop at the first click though and don't give it a couple just to be sure.

Took your advice and retorqued the bolts .. finished the engine and v2 charger installation today and runs like a dream .
