SlateFox.... dont throw your Sparkplugs away. I have used my old plugs for jsut that....plugging holes temporarily! Today, Mike told me to take off the AAR and figure someway of plugging up the hoses while I let the car idle...guess what I used? AND... when my AFM boot hose had a leak.. I put a plug in the nipple on top of the Hose.....she started. After 18 months...it was that plug that helped me to start her. So...something arent so bad to keep.. I have more old ****... lol! Ya never know! Now, want buy some used injectors? )
Jack what the **** you talking about? No humour in posts???? Im STILL laughing over the ceramic coated internals!!!! HAHAHAHA!!!! I know he couldnt have been serious...could he? )
Cleaning plugs with a grinder is a WASTE of time IMO. Sort of like putting lipstick on a pig will make them look pretty is all. If the plugs are firing properly and engine has correct a/f they would clean themselves.
Plugs are not expensive and can rob the engine of performance. Save money by not using higher than neccessary octane and using new plugs when needed.
I had carboned up plugs earlier this year after my temp sensor connector came off. It was so thick the car would not start.
I soaked the plugs in diesel and wire brushed the plugs. They did not look so bad. After a couple hundred miles, they looked normal from the cylinder environment's cleaning action.
