[quote=bluejay432000;3239972]Extraction is usually successful if the TSB is followed closely. That means using the correct solvent and letting it soak the correct time, etc. Those that have broken plugs can usually extract them with the special tools. It should be rare that anyone has to remove a head. Also, I think it is important that gas with a good detergent is used. I have also seen some posting that they broke a plug after running p1 octane. Little did they realize they were doing more harm than good when the engine was tuned for 87.
BlueJay432000,
Are you saying that it cause's more harm to the engine-plugs to run premium unleaded fuel in the KR Truck? I should stick to 87 as opposed to 89 or 91 fuel ? Please educate me, thanks.
