![]() This is cause by poor seals between the ceramic insulator and steel based. My miss was strictly when starting off in first gear, but can also happen at much higher rpm's. This kind of sinks in after doing this for over 60 years. Here we go again with bending over.Īlso in the science of electrostatics, the edges of the electrodes should be perfectly square, rounded edges greatly increase the ionization voltage on the plugs putting severe stress on both the coil and electronics. Did get into a discussion on a pro board, a mechanic said, just to bend it over, but apparently is knowledge on electrostatics is somewhat limited. The ground electrode should be parallel to the center of the electroded, use forming tools on this. Apparently somebody was thinking ahead 50 years ago when I purchased mine. Should only use a wire feeler gauge for gapping plugs. Anti-seize retards that, as does coating the inside of the booths with silicone grease, try and remove those boots with even 40 K on the vehicle, bake on hard and will break them in pieces. But not buying an expensive aircraft engine, more like a throwaway head. On better equipment, like aircraft, use a stainless steel nut cast into the aluminum, so that isn't necessary. They never heard of electrolysis and since that base is a current conductor to the head, you do have electrolysis. This was some other idiot putting a steel plug in an aluminum hole. Also good to grow a fingernail so you can release that coil pack plug without breaking it.įor materials, a can of Permatex anti-sieze compound to just put a very thin coating on the threads. If new at it, a torque wrench is also advisable. I use a 12' extension because I don't like to bend over, especially if there is anyone from the government standing behind me. A 5/8" spark plug socket, why are these still SAE, everything else is metric. Guess you do need some tools to change and gap your plugs. They'll (especially the BMWs) live for the warranty period on that sludged up oil, and THEN explode.Įver tried to back a spark plug out of an aluminum head after 100,000 miles? It's really not easy/pretty what can happen.Ĭlick to expand.Ha, what idiot would clean their spark plugs with only 16K on them, sounds like me. Chevy/Toyota/Honda all tote 10,000-mi change intervals BMW a 15,000-mi change interval. It's the same thing as the crazy oil change intervals these days. It's Platinum plugs that you never, ever want to use in a forced-induction engine. ![]() My Cruze is running copper plugs (I was just trying to isolate another issue and have been too lazy to switch them back), and runs just fine. However, manufacturers such as Chevy want to tote the "low maintenance" requirement of their turbocharged engines, so they chose to go with Iridium plugs at a pre-set gap that the manufacturer (NGK) failed to gap correctly for most 2011-2012 model year Cruzen. ![]() Click to expand.Copper plugs are pretty normal for boosted applications because they generate an extremely strong spark. ![]()
