 This happened today, reckon the belts slipped after this bolt was loose and got between a pulley and the belt, sending timing out and slashing the belt. Not sure if the head is s**teyed yet. I m thinking these bolts need loctite on them, check yours now! |

Look like an inner cam cover bolt possibly, although it's so long since I've done a belt on a '6' now the memory is struggling a bit...________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Yep, 6 bolts on the inner cambelt cover, mind allot of people don't use thread-lock when fitting them back in the head, A huge no no.________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |

My head was rebuilt before I owned the car a few years ago. Getting my local garage to put a belt on and time it up, guess thats when I find out the bad news. The car is currently sitting on a ramp next to 3 escort rally cars, a classic 911 rally car and a 6R4. Will try and get some pictures next week. |

If the belt has slipped/jumped or come off you WILL have piston to valve contact.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Do these heads respond well to a bit of porting and polishing? Pre incident it was producing good power but if the heads being rebuilt how can I improve things? Dont want to change the cams and not intending on charging it |

They don't need porting, they flow extremely well as standard. Just make sure when it's apart you check every valve and guide, get the head pressure tested and skimmed and a new set of valve stem oil seals. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I had a very similar problem to this after i drove my 6 home for the first time.It sounded like a tractor and turned out there was a bolt wedged between the belt and the cambelt cover. It gauged out a line around the belt. Apparantly a bolt or two got in with the camshafts too at some point and they had to be machined again. But it somehow didnt damage the head. Sounds sweet as a nut and has done since. Hopefully yours will have the same outcome ________________________________________ ''Oh, it does handle like a golf!''

Probably a sensor which hasn't been plugged in somewhere when putting it back together...________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |
