Title: Antisieze on spark plugs Post by justin_o_guy2 on 06/02/18 at 09:46:49 There's a radio show on Saturday about vehicles and maintenance. The guy gets questions and offers suggestions for solving problems. I was just out there listening and it was about Antisieze on sparkplugs. He said that without the metal to metal heat sinking, it raises the temperature range of the plug and can be the reason for a burned piston, as that was what some F1 race teams discovered. Some plugs are treated with a dry Antisieze from the factory. He said it's okay to use it, but just a dot, not a pass with the brush, http://www.nissanpathfinders.net/forum/topic/35354-why-you-should-never-use-anti-seize-on-spark-plugs/ Found this that agrees with him. My approach just got changed. |

Title: Re: Antisieze on spark plugs Post by Gary_in_NJ on 06/02/18 at 14:03:50 Antiseize is like Franks Hot Sauce to me; I put that sh!t on everything. If it doesn't get loctite, it gets antiseize. |

Right on ... If it doesn't move it needs WD-40 - if it does move it needs duct tape :P |

Title: Re: Antisieze on spark plugs Post by MMRanch on 06/03/18 at 16:10:30 I've got a crazy nephew who pulled one of the plugs out of his GSXR 750 to replace it Well the motor was still hot when he put the new cold plug in and guess what ??? !!! ::) Next time he tried to get that plug out --- it was stuck --- so much so that the plug twisted into just below the hex head So , he brought it to me to fix. ;D I ask him : " Jed , you mean you put a cold piece of steel into a hot aluminum hole ? and tightened it up ::) I did offer to guide him through taking the head off so he take it to a machine shop. But , he found one of his crotch-rocket bud's who wanted to see the inside of one of them bikes ! They're still fixing it 6 month latter :-/ . I wonder if anti lock cream would have help him if it as applied in time ? |

Title: Re: Antisieze on spark plugs Post by Armen on 06/03/18 at 16:29:35 First, I doubt that anti-sieze would change the plug temp. Second, I read the plugs, and change to a different heat range if I feel the plugs are too hot or too cold. In 40 years of putting a little anti-sieze on plug threads, I've never had any grief. Had lots of grief with plugs that someone else ran dry. Once got called to help out the Broadway show about Buddy Holly. The actors rode onstage and off on little Hondas made up to look like vintage Triumphs. Because the bikes never warmed up, they were almost always on choke. Fouled the plugs so often that the guy in charge just installed new plugs for every show, so 8 plug changes per week. After a bit, most of the plug holes were funnel shaped. I went in and Heli-Coiled the really dead threads. Gave the guy in charge a bottle of anti-sieze. Never heard from them again. The guy who taught me to do that at service school built the BMWs that won US Superbike, and later the Hondas that did the same. Oh, and he was an engineer for NASA before that. Kinda believe him. |

Title: Re: Antisieze on spark plugs Post by badwolf on 06/07/18 at 14:31:03 Let me get this straight,,,,,,, you are comparing our S-40 engine to a F1 engine? RIGHT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I don't think so! I anti-seize everything that might have to come apart,,,,,EVER! If I was to worry about it coming loose I safety wire it. |

I didn't consider how different the engines are. I was considering the report, and the Similarity of a spark plug, thermally insulated from the heat sinking ability of the head, allowing the plug to heat up enough to create a burned piston situation. That's what they reported learning in F1. I really THOUGHT I Explained that I didn't have experience with a problem, in spite of using Antisieze for years. Is it even possible that you have been being a jerk? |

Title: Re: Antisieze on spark plugs Post by badwolf on 06/07/18 at 14:59:17 Guilty as charged. BUT, I try to keep my revs below 13,000! Come on now, comparing our engines to a F1 engine is just sooooooooo wrong in so many ways! The only thing the same I can think of is both have aluminum blocks. (unless they have gone to carbon fiber or something) |

Title: Re: Antisieze on spark plugs Post by justin_o_guy2 on 06/07/18 at 15:02:37 I despise explaining the obvious, but I will. Spark plug Combustion chamber Head Head heat sinks plug Plug, Without a heat sink Could get hotter than intended Potential negative results You're really smart So Ignore me I'm a dumbshitt |

Title: Re: Antisieze on spark plugs Post by badwolf on 06/07/18 at 15:51:15 I'm not trying to start another ''war'', but a F1 team most likley spends more engineering hours every month than Suzuki spent in the whole Savage r&d. Just a slight performence safety margin difference from a S40 to a F1 engine. Those engines run on the ''edge'' all the time, while ours are just a little bit ''laid-back''. We have more of a safe range than them. A old John Deere tractor and Top fuel race car both have a spark plug for igniton. The tractor plug will last years, the Top fuel plug about 300 feet. Engineering stuff like that is part of the ''cubic dollars'' fun of racing. |

Title: Re: Antisieze on spark plugs Post by justin_o_guy2 on 06/07/18 at 16:48:38 According to the report The f1 teams were experiencing occasional piston holes they could not understand until someone discovered the connection between the Antisieze and thermal insulation of the plug allowing the plug to cause preignition. Believe what you want I'm done |
