Thanks

Some people use some don'tPeugeot use a bony as standerd that is adequate for the job, the standerd gasket is like1.5mm thick So fitting a thicker gasket means less of the thread is in the head, so less thread is gripping and securing the manifold You need to be able to tighten it down correctly to ensure a good seal as an air leak at the manifold causes all sorts of running issues |

Not required, the standard bolts are absolutely fine.As for tightening down the inlet, the correct torque load is only 20Nm. ________________________________________ Rich |

Thanks Rich. What does 20Nm feel like on the internal torque wrench?! |

Just don't use anything on the faces of it like a sealing paste as it will deform with the heat. Happened to a member on here. |

^^What he said, they don't need anything on the sealing faces, it won't bond to the ptfe and just stops the faces gripping and the gasket squeezes out. Pay attention to the torque too as overtoquing dooesn't do them any favours. If you have one of the black carbon/mica reinforced ones they're a bit more tolerant of abuse though.________________________________________ - Bespoke rollcages/additions/adjustments.
