Do my plugs look okay?

[Ill-EagleTSi]

These are NGK BPR7ES plugs that are about 2 months old. Does it look like Im running rich or lean? The tips are like a tan color but the threads are BLACK. Sorry for the blurry pics.

 

[92AWDHX40]

normal, from here the pics blurred.

Looks normal to me for 2 months of driving

 

[Rob10_99]

Looks a little rich, but looks fine as long as your ground strap isn't getting buildup like the rest of the threads. At least its no melted =)

 

[Gstclipse69]

Plugs look normal, but Seafoam that sucker to get rid of all that buildup.

The whole entire engine is brand new rebuilt...do you really think i still need seafoam? The reason I asked Is cause I dont have my Wideband yet and I was scared Im running it lean.

also keep in mind that if you just recently drove a short distance or had it idling without a good drive and gettting it up to operating temp your plugs will look like that because the excess wont be burnt off, and your car is very inefficeint at idle (run rich).

Sorry to hijack but what would make the bottom of the plug to be an orange color???

 

[Rob10_99]

Bottom being the ceramic? overheating the plug, or running too lean. Heat ranges are the number in BPR7es for example. If your at a good AFR, and still burning plugs, go up a number and it will handle higher temps better than your current plug.
Start a new thread and/or search I'm sure its been covered =)

 

[98gsxtuner]

I searched but ya the lower electrode I'm currently running 6's I'll switch to 7's and see if that helps. Ok no more thread hijacking sorry man.

Looks rich to me?? Mine is always a nice toasty tan/brownish color with none of that cabon on the threads! 14.7 afr and a 10.8:1 wot afr.

Is the black sooty, or slimy? If sooty I'd call like the rest of them .. a little rich on the fuel.

But a bit slimy, I'd call valve seals or oil rings aren't doing their thing too well.

I'd shove in some "6's" and see how it goes.

..my .02 cents worth .. - DSM

No they are NOT slimy or oily. Its More like a black dust...It would wipe right off if I used a rag or something.

I am ordering a wideband ASAP...BUT my only problem is I have an Exhaust Cutout that opens my exhaust up to a 3" open downpipe.

My question is HOW can the Wideband get a good reading if my exhaust cutouts before it reaches the wideband o2 sensor?

Is there any way to tune without a wideband? I have a SAFC II with narrowband now
I just wanted to know if im running rich or lean...cause I have taken the car to the track a few times and I dont wanna blow it up. The engine literally has 947 miles on it since it was rebuilt.

 

[LocknessMonster]

Its kinda hard to see with the pics but a tan color is good, but I would take it easy till the wideband came in. If they start turning more of a white color then its too lean.

 

[Rob10_99]

When you get your wideband put it right after the turbo and have about 3' or more pipe on it. That will give you an accurate reading.
Is your current narrowband sitting behind the oil pan near the firewall? or is it off the 02 housing?

 

[98gsxtuner]

We have 2 o2 sensors right one off the o2 housing and one after the cat???

 

[USER_22]

They look pretty good even though the pic is a bit blurry. Use some sand paper and you can get the black off the top of the plug. Make sure you have it really clean between the gap to avoid any idling or driving issues. Hope that helps.

 

[USER_22]

Yeah that's correct. Even though the one right after the cat is a bi*** to plug up after you unplug it since the hole is so tight. I was at it for like 2 hours trying to plug it back up.

 

[98gsxtuner]

So then if you install a wideband we have 3 then. I've heard of people taking the one out after the cat and putting the wideband there is that the wrong way to do it??? Should you just leave the one after the cat in and put the wideband 3' after the turbo??

No we just have 2. You use the wideband on the 1st one right under the engine bay.

Ok so we install it on the o2 housing. I'm just wanting to make sure i do it correct when i get mine.

 

[USER_22]

Yeah, or you can weld a new bung into the down pipe pipe. It's much more accurate the closer it is to the turbo.

 

[98gsxtuner]

Wouldn't the car run funny with that o2 takin out of the o2 housing.

 

[USER_22]

Well it would be less accurate with the readings since you would only have 1 O2 sensor in like that. Personally I would just weld a new bung in there if you want to keep both O2 sensors in there.

 

[JFZERO ECLIPSE]

Leave the o2 sensor in the o2 housing alone...Please don't touch it..

Your car needs that front o2 sensor to tell the ecu to either add fuel or take it out...Removing it would be like having your mas unplugged...Car just wont run correctly..

I would personally either:
1. Put it in the downpipe...Just need to weld a bung into it...
2. Remove rear o2 sensor...Leaving it plugged in just tie it up out of the way...and install the WBo2 into that hole...(The rear o2 sensor is only there to make sure your cat converter is working properly...It does NOT have anything to deal with your fuel control...Worst case you might get a CEL (Check Engine Light)You may want to weld a bung into the catback portion to have both sensors side by side...)
3. Same as 2 BUT remove the o2 sensor by unplugging it and use ECMLink to turn off that CEL thus you wont need to wend an extra bung in)

Either way make sure you use antiseize on all threads....
