| Post subject: | Anti-seize on manifold studs |
I'm just about to install new extractors ... and I thought it might be useful to replace the manifold studs and copper nuts. I'm wondering if the manifold studs should have any sort of anti-seize lubricant on the thread that goes into the head? I've read copper antiseize wont last with heat. Also read that metal based anti-seize can damage O2 sensors. Wondering if ceramic grease (the kind used for brakes) should be used? Or just thread them in neat. |

Think about it. How is it going to get to into the exhaust system on a mini unless you covered absolutely everything in it? That means there can't be an issue with O2 sensors. |

I was under the impression the idea of brass nuts on the exhaust was to prevent corrosion causing the nuts to seize so nothing else is needed. Interested to hear if I'm Wrong, |

Its the thread going into the head... I'm just trying to avoid any potential future pitfalls more than anything. You're probably right 68+86Auto.. if the cooper grease does melt.. its fairly unlikely to enter the manifold. |

I've anti-seized pretty much every fastener (unless threadlocking required) on my cars, including those with sensors, for decades with never an issue. It's so nice to simply just undo something years, even decades after you've fitted it... |

Yep, doesn't do any harm. It will never reach the cat; it seems to specialise in getting into your mouth more than anything. |

I use the nickel anti seize now. I had copper anti seize on the LCB Y piece and had to cut one pipe to get it off. Too hot there for copper. Edit You don't need it on the manifold studs into the head. Or on the brass nuts either. VW beetles used it on their exhaust studs, but they had steel nuts. |
