| Post subject: | Changing spark plugs - use anti seize & what type? |
I'm about to change my spark plugs in my j20a and am a little more curious about using anti-seize. I used anti seize the last time however I'm reading that using it may cause problems. Is it wise to use anti seize in aluminium heads? If so what type - copper or nickel-based? Some people say copper, others say nickel-based for alloy heads. |

It's not about being too tight. It's about dissimilar metals (aluminium head and steel plug) going though repeated hot/cold cycles causing the seizing. Or that's what I'm reading at the moment. |

I always use anti-seize on my plugs. I don't put them in tight but just like the idea of using it, and I'm paranoid what you said about aluminium head and steel plug. I have removed many a plug (not my cars) that you just about have to use a 4 foot bar on to get them out. Never had one snap on me and what a pain in thebum to get out if it did break in the head. |

Copper is what I would recomend, nickel is generally used on stainless fastners |

I always use a small smear of copper anti sieze. It also helps to keep the firing voltages down |

Its particularly important IMO on motors that run 100,000km plugs and back on the question I've used copper eze on my plugs for 10 years now and never had an issue. I use it on all plugs even ones into steel heads . its great on wheel studs too. |

Wow 100,000kms on one set of plugs... i can see why they seized up in the head, and why you would be concerned about it happening again...

Because a V6 in a east west configuration need to have the whole intake manifold and associated componets removed and it can be up to $850 to replace 6 plugs. Some plugs retail at $45 a plug too |

Yeah, platinum and iridium plugs are good for 100,000kms |

I've sold a few of these 226g tubs of Nickel Anti-Seize on E-bay for $20 plus post, still got a few left (Coke can not included). Should last you a lifetime of plug swaps. |

never used anti seize on spark plugs. never, not once, had an issue taking them out either. worked at a wrecking yard, lost count of the motors ive had to compression test, and yet again, never had an issue with plugs seized in the heads. like oil filters, if you use the correct procedure putting it in, you shouldnt have an issue taking it out, alloy is soft, so if you tighten the plug down to one billion foot pounds, anti seize or not, your gonna have issues. that saidm 100,000k plugs are probably worth using anti seize on, but using them on your standard 10,000k plugs would be a waste of money, unless the valley where your spark plugs sit is constantly swimming in water. |
