So anybody being a test monkey and have these installed yet? Comments...
Thanks, I will check that out as well. Its been about 180k miles since I had any issues with that cylinder, may be random, but at it is a senior citizen now.You might want to check the injector tip on that cylinder, it might have some buildup on it or some of the holes are plugged. Something is going on in that cylinder.
RockAuto is my friend... I was honestly taken aback at how much oil accumulated. The $25 can I got on amazon is very nice and fully machined from aluminum, with O-ring seals. Came with numerous adapters and hose clamps. I do not know how they sell them so cheap for the amount of machine work involved, even for China.Looks great! I cant believe I have not installed a catch can yet. I have complained about the amount of oil that runs through the runners for years. Surprised I don't consume oil in any quantity actually. I think most people would be satisfied with these plugs. Its a mentality of, is it going to cause harm? Looks unlikely. Are they going to outlast OEM? Looks likely. Will you save any money? Likely 19.99 vs 11.99 each from RockAuto.
i just did my spark plugs for the first time this weekend at 105K. All the OE plugs looked good except for #6. Looked brown. Not as bad as the 2nd picture you posted above, but different than all the rest of the plugs. Maybe there is something with #6 that has a common problem. I know on some cars the outer cylinders do not get as much cooling, the water passages don't flow well, and the cylinder over heats.Ok, So didn't want to hijack this post on my trucks issue. I pulled the Ruthenium plug in question today, really hoping for it to be toast and the end of my problem as I keep a set around. Also, I would commonly agree with Bajasam in most vehicles though I can only speak for mine. I have run many other plugs and plugs have been probably my most repetitive repair or tinkering over the nine years I have been running this truck. I have found that the ever annoying, just run OEM, or stick with NGK statements that I see littered all over this forum to be very true. This is the first engine I have run (out of MANY) that really does seem only really like NGK's, specifically the stupidly expensive Laser IR's. Those are the only plugs that I have run in excess of 50k with zero issues and only changed out of concern for a long trip into the sticks or the like.
But back to the Ruthenium's. I think I love them. I have not noticed any of the advertised benefits and most likely because I do not have any of the needs that they were built for such as GDI, Turbo, or Supercharging. What I will say is that when I pulled the plug, it damn near looked new. So I pulled five of them (Ya'll know why 5) and they all looked great. I did change #6 since the coil was shot and repeated the issue in #4 when moved. So in all, I guess I don't care about the performance benefits, I am guessing they will out live the NGK LR's by 1.5 or maybe 2x the life. That alone is hard to imagine. So I changed the coil and all is well. Coils had about 90k on them and were Amazon cheap o's. But whats cheap if they lasted almost as long as OEM's I have included a few pics and when I said still look new, well, comparatively with mileage. I have pulled others out with simular miles and imeadiately replaced with LR's while laughing that I wasted more money on another gimick, i.e. Pulstar's and others. Hope this helps, I would reccomemnd and hell, they are $8-$9 a plug cheaper then the Laser Iridiums.

Yeah, six has always been dirtier than the others on mine. Its always the first to look at if I have any thoughts of a problem. I travel a lot, so I often wonder if the fuel I get all over the continent is good. I run a can of Royal Purple Fuel System a few times a year, but I have always thought that to be which crafty wives tails. I don't really know if it helps, more like Redneck Insurance to me.i just did my spark plugs for the first time this weekend at 105K. All the OE plugs looked good except for #6. Looked brown.

I replace with NGK platinums, the same ones that came in the truck.
I also spent some time to scrub out the lower intake. There was a bit of accumulated oil in each runner. Of course while I was in there I dropped in a IMS.
