x2 - the only plug that looks out of the ordinary is the one on the far right. I x2 the compression check too - if it comes out OK, I wouldn't worry about it.
x2 for the coolant flush/fill ... looks like maybe they had put some stop-leak in there, which is OK for a temporary fix, but can have negative effects down the road (namely plugged heater core). Have the coolant system flushed by machine and fix any leaks properly.
If you haven't had the head gasket recall done, why don't you make an appointment and take it in? They will freshen everything up and it won't cost you much since they are already in there ...

You can get denso/NGK plugs at most auto shops, just ask for then specifically so they don't hand you Bosch

when i worked at rays automotive part of or employment requirements was training so he would do extensive research on certain subjects and give us his results and randomly ask us about it one of which was the good ol coolant subject tho its been a while back i believe one of the top performers was (and yes i hate to say it) ford yellow now thats not including the bmw blue or toyota red etc... that was just green orange and yellow but of all the coolants the green failed the worst turns out the anti corrosive agents actually worked against itself not to say they havnt reformulated it since these results in 07 but probably not

It looks like you could be over fueling. Before I rebuilt my carb, I was overfueling badly, new plugs looked like they had seen years of use after a couple weeks

Yotapowa..........maybe a good point I do have a problem with the 4runner flooding out when starting at cold and sometimes when engine warm so maybe a leaky injector or injectors?.....but goo call thanks.....but what about the smell of the plugs?....I have never smelled plugs like that before don't smell like burnt oil just like kinda weird like rubber hose or something...

looks like they may have used copper block seal to try to seal the headgaskets. Have you done a compression check yet? That should give you a better idea of how the motors health is looking. Be carefull flushing the coolant, you might flush out what was plugging a possible headgasket failure. You might also want to invest in a coolant system pressure tester. Fill up the system, pump up the tester and let it sit for 15 20 minutes and see how much pressure was lost. It's the best way to test for coolant leaks. Good luck whichever way you go.

well the compression test I tried this past Saturday it was really cold here in Ga.....my compression gauge went south on me and my engine was cooling off quickly so I just put some new plugs back in and called it a day
I will try to locate a coolant pressure test gauge where can i purchase one?....and are they expensive?

Buckz, I picked up mine at carquest. Shmuks/ schucks should be able to get you one. They can be kinda pricey. Carquest has a complete kit for about 300. I don't know about harbor tools. I'd call around to a couple shops and see if they can pressure test your cooling system. Or check ebay, but they are worth their weight in gold when you're looking for those small leaks. Last time i saw coolant like that was a blazzer that had dexcool, horrible coolant. Once again, good luck.
