Hmmm Ok new problem when car is up to running temp (90 degree on oil, 70-80 on water) I'm getting the oil and stop light coming on at idle and then its flickering on off? soon as i touch the throttle they both go off ? Have recently changed cam belt and cam pulley for an ally job. Got plenty of oil in the old girl but i will be changing it at a matter of course ? Anyone got any ideas as to why this is happening ? Bad sensor ? Too thin oil when hot ?  |

Did you torque up the bottom pulley when you did the cambelt Chris? If it is an older engine it will not have a keyed slot to run the oil pump drive and will be relying on the tightness of the crank pulley bolt for drive. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Hmmm I was thinking exactly this Stan ? used the windy gun on a compressor as trying to tighten up with a spanner usually turns the engine over ? |

My bets are on this - what drive windy gun did you use? They need to be fooking tight!  ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

When I do these, I usually get a mate to put their foot on the brake with the car in 6th gear to lock the engine.  It can only be a few things mate, it's either this issue, a dodgy sensor/wiring or the oil is too thin.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Changing oil anyway and will tighten up the pulley bolt FT ?  |

I actually undo and do these up using a breaker bar and a very long extension bar Chris. Also, don't forget to Loctite it. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Off the top of my head I think the torque is 130Nm but check it to be sure. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

It is tight, but as I say in the older style engines this torque was needed as the oil pump drive sprocket relies on this pressure to drive the oil pump. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

130 isn't tight, it is 210 on the K series! I usually use a bar as Stan has indicated.Can also do them by locking the flywheel. ________________________________________ I'm Si btw Night Blue VW Golf GTD Bianca LBSC Rallye - Track/Road Slag Project Thread Sparkling Silver Mini Cooper D - Super Dooper  - (The other half's wheels) |

I'm guessing this mess is caused because he doesn't have one? Otherwise this is a prime example of why torque settings exist.  ________________________________________ I'm Si btwNight Blue VW Golf GTD Bianca LBSC Rallye - Track/Road Slag Project Thread Sparkling Silver Mini Cooper D - Super Dooper - (The other half's wheels) |

Must admit, it's good practice to keep one handy especially for critical jobs like these. I don't like the oil pump drive system on the early engines due to this issue. I prefer having the assurance that it's driven via a keyway off the crank and I'm not suddenly going to be left in the middle of nowhere with no oil pressure. It's not that hard to swap it over to the new system, sump off, cambelt off and remove the front oil seal housing then swap the drive pulley and rebuild. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Right I have had the breaker bar on this today and it's proper tight so I don't think that's the problem ? Had the car running again , lights on again once water up to and above the half way point ? Oil not warmed up fully, soon as you touch the throttle they both go out ? I'll change the oil tomorrow and see if that sorts it ? Failing that could the oil pump be on its way out ? Chain can't be snapped surely ? Could be the presure switch I guess ? |

get a mechanical check done pump failures are rare, wont be the chain as you do have pressure when revs go up, whip the crank bolt out and make sure its not bottoming out on the nose of the crank. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

If the bolt wasn't tight enough surely the light would be on all the time ? Ie no pump working ? Just seems odd that the lights come on once started to warm up and only at idle ? |

Could be the switch itself gone faulty and it's actuating at a higher pressure than it should.I agree with Welshy, have it mechanically checked first, better safe than sorry. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Will bang another switch on it tomorrow and drop the oil ? Yes a mechanical check would be good but going to eliminate the obvious first |
