Diagnose my spark plug photos

[hooRAH]

I just replaced the plugs today. Old ones don't look terribly out of the ordinary to me, but mabye an expert can give a more detailed analysis of what they see. Sorry, I couldn't tell you the mileage, but I do know that the engine was overhauled for sludge at around 75,000 miles, and the engine is at 150,000 miles now.

That sparkplug looks terrible, the groundelectrodes are melted and has a white coating
and the insulator on the center electrode is bone white, looks like its been running too lean
or the sparkplug is the wrong heatrange or the ignition is to advanced.

I say its his flash that makes it look so white. Otherwise it looks normal. Use a wire gauge to check the gap, maybe it is 1.3mm now.

The electrodes are not melted, but they do have a white coating.

Its not the wrong heat range, its a denso OE plug.

Ken, yes, I was having trouble getting a non-blurred picture with the flash, and the flash shows in that picture. I think its normal wear, its just old. Oh well, new NGK went in, and the idle smoothness improved slightly. Would have liked to see what it did to the fuel economy, but I haven't been keeping track at all. Thanks for looking.

Cant tell a damn thing from this photo. Check your tail pipe, is it light gray, tan? if you were truly having problems, the CEL be on. i have seen plugs from all my 10 cars and yet they kept doing what i wanted them t o do - drive me where i want to go, and pass smog.
No worries.
