Graham Perry Posted April 13, 2006 Share Posted April 13, 2006 What lubricant to people put on the threads of these so that they don't get tight due to the heat ? Link to comment Share on other sites More sharing options...
Sheds Moderator Posted April 13, 2006 Share Posted April 13, 2006 Coppergrease? Good for brakes and heatproof. Link to comment Share on other sites More sharing options...
Paul Deslandes Posted April 13, 2006 Share Posted April 13, 2006 Steve Greenald advises that you should loosen them every 6 months or so and re copperslip to keep it free. Even with copperslip mine was a bu99er to get out after a couple of years. When you to go to Steve for a rolling road remap, he takes the your lambda sensor out and puts in his own 'known' six wire unit. Link to comment Share on other sites More sharing options...
Neill Anderson Posted April 13, 2006 Share Posted April 13, 2006 You need to be VERY careful not to use too much of whatever anti seize compund you do use. The compounds can give off fumes etc that the sensor can detect and thus it can read wrong. New Bosch sensors, and NGK ones come prelubed with a tiny amount of something on the threads. Too much can be worse than too little! Neill Link to comment Share on other sites More sharing options...
Graham Perry Posted April 14, 2006 Author Share Posted April 14, 2006 The reason I asked is that the sensor instructions say DO NOT use copperslip, but very helpfully then go on to not tell you what the alternatives are Link to comment Share on other sites More sharing options...
Sheds Moderator Posted April 14, 2006 Share Posted April 14, 2006 In which case you can buy proprietary antiseize compounds but some are expensive. A weak Loctite will work, if it stands the heat. After all, when did you ever have trouble undoing a Loctited chassis nut,compared to a dry-assembled corroded horror? Link to comment Share on other sites More sharing options...
Paul Deslandes Posted April 14, 2006 Share Posted April 14, 2006 'Normal' Loctite tends to break down at high temperature but still leaves a powdery deposit on the threads, which keeps the surfaces apart and, maybe, from corroding. Heating a loctited joint is the recommended way of getting them undone, provided you won't damage anything else with the heat. So perhaps in a very hot exhaust environment it might act as a release agent instead. And you're not looking for thread locking anyway. Hmm!

Mike Biddle Posted April 14, 2006 Share Posted April 14, 2006 Copperslip is not much use at very high temps, we use a nickel based anti seize on diesel engine manifolds and turbo bolts. Never had a removal problem yet. Link to comment Share on other sites More sharing options...
Bricol Posted April 14, 2006 Share Posted April 14, 2006 Locitite do a range of high temp anti-seize compounds - but I can't recommend them as I'm still waiting for them to get back to me over a graduate recruiment interview (two of them) despite me calling them a couple of times - and that was over 14yrs ago . . . But more on-topic, if you do wreck the thread, this here might be useful . . . Bri Link to comment Share on other sites More sharing options...
