Just changed my spark plugs! pics of old vs new

[max20s14]

Did it without raising the engine. Was a PITA.

Busted knuckles guaranteed. I'm right at 60k miles and the plugs don't look great to me notice the white part of the spark plug. It has some corrosion starting to creep up from the head. I'm not sure if that is normal but perhaps one you you guys can chime in

I've seen that and I would not be concerned about it. Mostly surprised that there was no never seize on the threads.

I never thought this was that hard of a job. I used a flex adaptor and a magnet to fish everything out, never had to raise anything either.

My flex adapter broke while trying
The hard part was seperating the extensiin from the socket. Since mine have those little detents
Used An extension a hose and a magnet. Ive read or heard somewhere your not supposed to lube these plugs

Looks like you could have gone another 30k miles.

Damn that would make it harder. I just pulled the flex out far enough I could see it connect to the short extension I was using, then shoved a flat blade in there and twisted them apart.

I never heard not to lube them. I don't put plugs in without never seize. I have fixed enough stripped threads I don't care to have to deal with it again if I can avoid it.

Easily. Looks practically new.

Those look almost pristine. Back in the carburetor days before ECU fuel/air management the plugs were good if they lasted 5,000 miles. To get 60,000 out of them and have them still look that good is a technological marvel and a true statement of how far things have come.

I was disappointed when mine were changed at 138,000 miles the mechanic didn't save them for me as requested of him. Really wanted to see what they looked like after twice the expected lifespan.

I will see what mine look like when I finally get them changed. Probably be three times the recommended mileage by then.

Yep, back in the day, I would have put those puppies right back in.

Today, if it weren't such a PIA to get them out, I would put them back in - but, since they are out - I'd replace em.

I would have run them through a blaster first though.

Anti-seize has always been standard on plugs going into aluminium heads for me.

Yep, fer sure. I recall back in the day to tend to spark plugs meant to stop in at my Uncles Chevrolet dealership, pull the plugs out, put them on the sand blaster machine, gap em and put them back in. The whole process was a 15 minute job.

Picture of a back-in-the-day dirty plug, for the young-ens that think their plugs, with a slightly discolored insulator, are "dirty". -

Plug condition was vital for diagnosing issues. The ECU has done away with many of those problems though.
