Yep, depends how early or late the engine is, it screws into the front of the block and will be a grey plug connector. There are different types for early or late engines.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

But it's not used daily so prob only done about 3k on the oil ? |

Best thing to do is to get hold of a torque wrench and just check it for piece of mind. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I'm wondering if maybe it's too thin when up to temp. Running a billet pulley and it's different to a standard pulley has a shallower centre so just making sure the bolt is not bottimg out ? Running 10w 40 semi synth ? As standard ? Changed plugs as well |

Ok, I'm running an aftermarket Rich_W pulley, but not needed to cut the bolt down, but hey ho. The oil as you say is correct, so it can't be that. The worrying thing is you have changed the switch and if it's still doing it then the switch can't be faulty meaning there IS a mechanical issue somewhere. The switch pressure is set so low that it only comes on when you literally have zero oil pressure, so to have it flickering at idle is definitely not good Chris. I'm thinking maybe the pump is starting to fail, and it's only producing reasonable pressure once it's revving. Maybe the pump gears are worn? It would be worth getting an oil pressure check done, whereby you plumb in a temporary gauge just under the bonnet and start it up and rev it etc and see what readings you get, my guess is they will be low and the pump will need looking at.

Well Stan that ain't going t happen before the weekend and I'm on the track at the weekend so see what happens ? Didn't have this problem before I had the engine out or the dash forward ? Only thing I have changed is the pulley, engine mounts, heater matrix, oil cooler, service, front end susp rebuild, quick shift, strut brace and coolant change ? |

That could be an expensive way to find out...Have you unplugged the oil pressure sensor when the light is flickering to check it is definitly that sensor that is bringing the stop light on? ________________________________________ Ryan |

This is normally a sign of engine wear in the bearings/pump especially as you have changed oil/sensors etc. Putting an oil cooler on will cause a small drop in pressure due to the extra work for the pump but shouldn't bring on the low pressure switch. What is the low pressure rating on the switches for these engines, 1bar?, 1/2bar? Get a pressure check done for piece of mind. ________________________________________ IPhase 3 Astor.

To be fair Chris, with an issue like that I wouldn't be risking going on a fast road drive let alone a track...There is obviously something wrong, and as Ryan says a trackday could prove a very expensive way of finding out what was wrong.

Will be taking it out for another spirited drive before the track ? If it goes bang it goes bang ? It's not hard to find and install an engine ? Especially for me ? |

Agree with the above. Having lost a few big ends on track its not fun, or cheap. Stan - cheers. ________________________________________ IPhase 3 Astor. Built on Wednesday, 12th April 2000 in France.
