Make sure the injectors on those two are actually firing , either use a light bulb meter or a DVM on the wiring.Secondly i would try a compression test. you only need three things to run an engine, spark , fuel and comression. Your claiming you have the first two  ________________________________________ You want tact ? Call a tactician !Xbox 360 : Cableguy1984 |

He does'nt know if the injectors are firing, just that it doesnt change if he removes them. Check the injectors are getting voltage if you can.Failing that, as said I'd be doing a compression test next. You have tried new plugs i take it, because if its been running on two the plugs will almost certainly be fouled by now. ________________________________________ R H Davey Welding Supplies.

A grinding noise will definitely NOT be caused by the stepper motor.________________________________________ R H Davey Welding Supplies. I sell new and used welding equipment in the Hampshire area.

blue sensor is nowhere near the crank  its the CAM sensor. my guess would be that the HG has gone between 3 and 4, same as AdamB's Rallye did end of last year. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

adam didn't lose any cooling system pressure, just all of his cylinder compression, so a compression test with all plugs out is the way forward.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I'd have a word with a local garage and with Carl, it may still work out cheaper than someone who doesn't know the engine [especially if they don't know about the bottom pulleys that can slip].________________________________________ Ex SC-6Now in a Megane R26 |

heat from the exhaust manifold warps the head and thus gasket faliure - seen it a million times now. Head off - skim re seat valves etc then new gasket seals bolts thermostat n seal inlet and exhaust gasket - job done no need to replace rings |

In theory yes but the heat is really just trapped within the tubing instead of disepating outwards. This could also mean higher head and valve temperatures. |

Not keeping a strong enough mix of antifreeze in there can cause corrosion in the waterways which eats the edges of the gasket (acid formation in the crevices from the corrsion).If you want it picking up and moving I've got a mate with a recovery truck that's not too bad on rates, rikky used him to move his car home after the cage. ________________________________________ - Bespoke rollcages/additions/adjustments.

No, wrapping the exhaust manifold will increase heat transfer into the head as it reduces the heat dissipation to the engine bay. ________________________________________ Rich |

So is everyone saying this is correct as that is one of the strangest things I have ever heard connected to head gasket failure? For the OP's problem what you are saying with the grinding noise then it going away and being on 2 cylinders sounds very much like when the head fell off a valve on my old one. Hopefully for you this is not the case and it will just be head gasket failure though. ________________________________________ Ryan |
