When it's running, move your hand arond the leads on the coil pack, if you get a faint shock, it will be aching out it's self. Or do it in the dark, and should be able the see the sparks. | |

If them figures are correct id say headgasket has failed between cy1-2, to be honest that might even need skimming. You would only loose coolant if it failed between a cylinder and a coolant passage and you would only have mayo if it failed between a oil and coolant passage. Them figures surgest to me that its failed between the two cylinders? | |

I did a compression today (forgot to remove fuel pump relay) and 1,2 cyclinders read 90 and 3-4 where around 220.Still no water lost and no mayo under cap.Any ideas? | |

have you had all 4 plugs out and looked at them? ive seen it before where the white insulation bit has a crack in it causing a missfire too. | |

Well yes it would be loosing water if coolant was getting into the cylinder as in my case but yours could have gone between two cylinders for example. Im not saying thats definataly what it is so dont go just ripping the head off cuz its a pig! Do a compression or cylinder leak test if possible. | |

If the headgasket had gone surely it would use water and have mayo under cap? | |

On my x14xe i had a slght missfire at idle and a really bad missfire under load/acceleration. I did have white smoke out the exhaust aswell though On mine it turned out to be the headgasket had failed in cyl4. I could see by removing the sparkplugs and looking down the plug hole with a tortch/camera i could see pistons 1-3 where black and piston 4 was shiny (see my project thread) also spark plug number 4 looked cleaner than the rest. | |

Hi my x16xe has developed a misfire.It idles ok a little rougher than usual (sounds slightly subaru ish) but when accelerating theres nothing just flat.It was fine then i filled the tank with fuel and the next morning it was missing.I dont think this is the cause but ive checked the plugs and leads just want some ideas on what to check.Any help or advice would be great.Thanks |
