| Nov 10, 2019 at 14:05 | comment | added | jesse_b | Penetrating oils have been proven not to help at all, and wd40 is not a penetrating oil. | |
| Nov 9, 2019 at 21:33 | comment | added | Criggie | @MTA also, a hot air gun can help with localised heating, if the engine isn't startable. | |
| Nov 9, 2019 at 17:18 | comment | added | R.. GitHub STOP HELPING ICE | WD40 is not penetrating and is not for breaking loose stuck threads! Use something like Pb Blaster, Liquid Wrench, etc. that's actually made for the job. | |
| Nov 9, 2019 at 17:17 | comment | added | Solar Mike | @Tonny not seen any spark plugs with plastic seals or rubber ones.. spark plugs have metal compressible washers to make the seal. | |
| Nov 9, 2019 at 17:17 | comment | added | MTA | If you have trouble getting the plugs out of a dead cold engine, it sometimes helps to run the engine until it's just barely warmed up, but not hot, and try again. | |
| Nov 9, 2019 at 16:16 | comment | added | Pᴀᴜʟsᴛᴇʀ2♦ | @Tonny - It has not been my experience WD40 will degrade plastics to any degree. I know it can swell rubber (natural rubber) if the rubber is soaked in it over time, but that's not degrading the rubber itself. Do you have any real references about this? | |
| Nov 9, 2019 at 13:06 | comment | added | Tonny | @vidarlo WD40 is corrosive to a greater or lesser degree to any plastic and/or rubber compound. If you've got full metal seals that doesn't make a difference but in many case there is some washer or grommet that isn't metalk. | |
| Nov 9, 2019 at 13:00 | comment | added | vidarlo | @Tonny most spark plugs I've seen has some sort of metallic seals. WD40 is not corrosive, and will not eat away the seals. It may penetrate the seal if it's not perfect, however. | |
| Nov 9, 2019 at 12:51 | comment | added | Tonny | @HandyHowie Given enough time (several days) WD40 will eat away some of the seal material. It is really nasty stuff. Just spray some more WD40 on every day and give it 3-4 days. | |

| Nov 9, 2019 at 9:21 | comment | added | HandyHowie | @GdD Since spark plugs have gas tight seals above the threads, is there really any chance that something like wd40 will help? | |

| Nov 9, 2019 at 0:35 | comment | added | smitelli | @GdD My tried-and-true formula for loosening any threaded object has always been some combination of heat, PB Blaster, and time. | |
| Nov 8, 2019 at 17:31 | comment | added | GdD | If you are having trouble use some penetrating fluid like WD40, and give it time. Engina the goddess of motors will not be happy with you if you use an impact wrench on spark plugs. | |
