Ripped into it last night, got the old plugs out, put new ones in with anti-sieze, will be buttoning it up today w/new boots.
I'll post pics of the plugs after I get done, #9 was pretty rusty colored, #10 had dirt in the hole, and most of the plug boots had dirt creaping past the top seal but not yet intruding below the second seal. #4 hole was also slightly more dirty than the rest.
Plugs are good color, all seats are shiny, looks like I got them in time
It could have lasted another year or so, but I'm glad I did them now.
This is with only 22K miles on it, but truck was manufactured 10/2000, so it's just over 5 years old. Aww....
Imagine my surprise when I opened the hood and found coolant leaking from the thermostat housing ... I'll be taking care of that with a $1.79 o-ring right after the COPs are back in.
Try 100K miles of gas at 5 MPG! That's what stop-and-go gets you with a V10
It's done, I also replaced the thermostat o-ring which was flat...
I'll post some pix later today, but I didn't do a step-by-step, just a few pix to show how dirty the boots were, and how good the plugs were compared to the ones in my wife's '97 4.6L.
haven't driven it yet - but I will in about 2 hours ...
It wasn't particularly hard. I put a car floormat on top of the hood latch, and a large comforter folded four times over that, so I had something to lay on. Used a step-ladder to stand on.
Plug #5 required the "feel around" technique, #4 was a little cluttered with all the stuff going into the right side of the throttle body. Other than that, it took very little time.
About 5 hours elapsed time, taking a break once or twice of 1/2 hour. It was my birthday Monday (turned 40!) so it was the only time I could get to do what I want without the wife going "does that really have to be done now?"
One tip: To get the spring off the coil terminal, turn the spring clockwise while trying to pull it out of the coil. There is a spade terminal in there, and turning the spring clockwise expands the spring so it comes right off.
Again, pix later today, but don't expect anything spectacular, I used the video camera.
Some day I'll get the cajones to do my plugs (85k on original set), I guess I'm just a bit intimidated by it all. I guess I'll see how my block heater install goes. If it goes easy, that'll give me the "idea" that I can handle the plugs too, if it goes south, there's no telling when, if ever, I'll change them.
Maybe I should just bypass any maintenance at all by going and buying a new truck.
I just bought mine and it's got 74k, so I pulled #2 and #9 just to get a look and see what I got. They looked ok, a little worn and over-gapped (about .62). #9 had rust on the top of the plug and the spring in the boot, so obviously we have a leak there. Can't be to good for electical transmission.
So, I guess I know what I'll be doing this weekend, plugs and boots.
