Normal spark plug wear?


Recommended Posts

Before I got my car, I was told it got a tune-up when I called the shop that worked on it. The car hasn't been driven much, so this is theoretically 300-500 miles of wear... yeah right. Unless this amount of wear is normal..

:shock: That looks more like 50 000 miles worth of wear. But i have seen worse.

i belive that looks like it was running hot, not for sure but the pics in any repair manual shows the different wear types.

that's about how the plugs looked on my '95 blazer when i pulled them out with 100k on it. those are nowhere near new, IMHO

its hard to tell from the looks of it as far as it looking like its not burning the fuel well and looks oil soaked, but the electrode shouldnt be worn down that much. might want to try one range hotter.

BOSCH? :puke: no wonder they look like crap. I's say probably 5000 miles for shit like that.

my bro's Cutlass had 2 boschs and 4 ac delcos in it, the engine kept misfiring, the bosches were burnt and oily. (but in fairness, i think they were two left when someone didn't finsh changing all the plugs.)

I also pulled AC Delco plugs from a 89 pontiac w tech 4. the center electode was worn almost even with the insulating tip. I measured the gap, is was 2 and 1/2 times the proper gap. With about 145000 miles, do you think that might be the factory plugs?

That's the worst plug I've ever seen. Before I came to this website, I actually thought BOSCH made decent plugs. Maybe they do, just not for our cars.

That plug isnt awful, but it is warn out. I put bosch plugs in dodges and fords, GM cars they have issues, but we have been thru this
