Aside he's the best one I have found to help diagnose and fix your car or truck and doing yourself can save you a lot considering that I only paid $1500 for that vehicle $1200 wasted in the shops knowing nothing more than myself

I only got 4 plugs changed in like 5 hours because the plugs were breaking off and refusing to come out. But the 4 that I got out were really healthy looking plugs according to you, so that's good. Especially considering the truck has 211k miles on original motor

    I changed mine in my 2007 Jeep Grand Cherokee Overland 5.7 liter it took me 4 hours. The gap on a new plug for my vehicle is .045". The burned up ones where Champion Copper Plus the gap was around .065"+ . The new ones I put in are Champion Platinum spark plugs the gap new is .045" and that's what there where factory gaped to. The MPG's have gone up to 21-23 MPG's at 55 mph on flat highway. The old ones I was getting more like 17-20 MPG's.

    Great and informative video, RnW. You didn't say what a normal working spark plug would look like. That is, one working in normal conditions, no lean/rich mixture, no oil leaks, no oil burn, no coolant leak or burn, no timing issues, etc. Also, what would a brownish looking spark plug indicate? Electrodes are perfect, and no excess deposits on the plug.

    This is helpful, I think it helps me understand what I found. 2020 Mustang 4 cylinder, 18K Miles. First few oil changes free from the dealer, decided I wanted to take over maintenance myself so completed my first oil change the other day. The next day I pulled the four spark plugs to replace and was horrified to find oil dripping from the threads on second plug from the back. I didn't think oil could be actually getting in when the engine was running because the car had been running fine, so looks like I must have overfilled oil despite being so careful. Now my question is, can this result in long-term damage? The car seems to run all right and I haven't seen any smoke out the tailpipe, so not quite sure where I stand.

    Great video!!! A spark plug in my 2010 Honda Odyssey is oil-fouled, and the dealership says it's probably the piston ring, because it happened again just after 9 months it was previously fouled. I just want to keep it running for the next couple of months until I trade it in for a new care.... Can I just get the one spark plug replaced, just to keep it running for a few months?

    Way2go sparky😁If I may, the insulator, beside the internal resistance, their integrity also worth regarding. Even if notice a fine dark line that can't be cleaned likely indicates a crack that will get noticed under operation. Careful removal & installation, with cleanliness, also concern for ignition system components because HV will find any break & deterioration along with any dirt oil fluid smudges.
