Damn, let us know what happens. The good news is that none of them look like a headgasket issue.

Just noticed a little oil on one of my plugs, I have a 03' V8. Im running full syn Oil and just replaced the plugs with the recommended Denso plugs.

My 4Rnner is running great! but the little bit of OIL i found worries me... I hope you get this resolved my man.

Update the guy at the local shop was just gonna keep charging to replace everything that he though was wrong so i had it towed to the dealer i was actually sad to see it towed away

 

[2007toyota4runners]

So I took it to the dealer and they said the two spark plugs had cracks in then and 280 to replace all 6

Damn, I'm in the wrong business...If you just bought 6 new plugs, why wouldn't they just replace the 2 cracked ones?

 

[2007toyota4runners]

they asked me if i want to replace 2 or all 6 and it want much difference in price and im starting to doubt my work so i just had them replace all 6 im just hoping the tech is right and i dont have to spend any more money

See if they can save you the cracked plugs to show you. I'm curious if it's easily visible to the naked eye. Sounds like they might have either been dropped before you installed them or you over-tightened them. Did you use a torque wrench when you put them in?

Some say 13, some say 15. Small difference between the two obviously. You shouldn't have cracked them if you used 15. Where did you buy the plugs from? Sounds like they were dropped at some point.

it has 76k on it but i dont know where each one was

i believe the NGK on ones were on the right when facing towards the engine

The NKG on the far right looks like it may have been the one with a crack...

they were bought from the dealer

I thought the issue persisted when you put the original spark plugs back in. Were those two cracked somehow as well?

the two new ones i had installed on 5 and 6 had cracks in them might have been dropped or damages during shipping

Im about to go pick it up from the dealer after getting all 6 of the plugs replaced Thanks for your help and concern guys

So it was just a plugs issue and the truck is fine now? If so, glad to hear it!
