You torque the head down when you fit it.  Did you do a complete rebuild or just drop a new engine in? |

Its very rare now for any engine to need to go back to have the head re-torqued down. Once its fitted that is it. So unless its specified in the tightening sequence dont worry about it, the GTi6 engine doesnt require it. |

 Provided you torqued it correctly to begin with, nothing to worry about.________________________________________  You feed beefburgers to swans. I may have been speeding Mr Policeman but [a] I live for the 306 and [b] did you see that dog? omfg |

if you wanna check the torque, use 10kgf.mthe std torque (3.5 - 7 - 160º) is superior to this value ________________________________________ Citroen ZX 16vXU10J4RS turbo |

I also agree with you here Fletch, when I do them I only angle tighten to 90 degrees, as the bolts feel like they are going to snap if you give it anymore than this.

what do you mean 90 degrees is this 90 degrees clock wise of a measurement of torque sounds like a dumb question ________________________________________ mclovin needs more power |

no neeeeed! if they're done properly you wont need to touch them ever only tightening a bolt to 90 is a bit stupid when the book says 180... ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

You can't check the torque of the cylinder head bolts once they have gone through the three stage tightening sequence. The last stage is the stretch stage of the bolts which is measured by degrees.I'd leave them alone. If the job was done properly you have nothing to worry about :-) ________________________________________ Gti6 running gear, Pug performance inlet cam, 4-1 ex/man, Modified in/man, decat, Magnex centre/back, cone air filter, AVO Coilovers, EBC grooved discs and mintex 1155s, stripped out interior, Oil Cooler, 17" rotasBUY IT, WRECK IT, BIN IT! |

I angle tightened mine the best part of 160 deg. despite Longmans advice  Had to use a MASSIVE bar to get them that tight And when I had to take the head off I snapped numerous extensions trying to undo them  Will teach me for buying Fisher Price tools though! A Snapon extension did the trick. I dunno if 160 deg. is too tight or not The bolts did feel like they were about to go  Having said that I've had no HG problems, despite the copious amounts of boost! .. touches wood… ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

They should feel like they're about to go, they're being stretched past yeildEven the TU ones do the same when tightened properly, it's a weetabix day. That's why you don't have to go back and retorque them like the head bolts of old. P.S. - If your worried about the amount of torque try a little moly-based CV boot grease on the threads, it'll make it a lot easier, don't torque them up quite as much in the initial stages though, ________________________________________ - Bespoke rollcages/additions/adjustments.

Sorry to bump up an old thread but how the hell are you supposed to hold the engine still (assuming its out of the car and on the garage floor) whilst doing the final 160 degree tightening?3 man job? ________________________________________ 1999 Astor Grey GTi-6 OEM+ (now gone...)2004 Aegean Blue 206 GTi 180 (also gone...) 2006 Skoda Fabia vRS in Sprint Yellow honestly3k wrote: Do you wrestle for a living matt?
