**Scottydoggs** · 05-04-2011

i had a friend years a go who was looking for a job, and we told him there was a job open for changing spark plugs on diesel trucks, he was so excited lol

and yes im huge ass sob, im 6'6, size 16 shoe, tall shirts or my ass hangs out, and the selves don't come close to my wrists, kinda sucks, but i like to see over everyone head, i even got the sausage fingers curse, pinky finger is a size 15, and 8 1/2 inch wrists

this is the only pic i have of my hand, my last grow some time ago.

Thank you everyone for all your patience and advice. You guys have been more than helpful!
Bill, Thank you for the offer of pictures and video, but that wont be needed. I know what your talking about except Im not sure what the "SC snout" is, and what the "LIM" is.....other than that Im all set for saturday.

he would have been referring to the area where the serpentine belt is on a pully at the highest part of the engine, but as i re read your first post you may be n/a motor, no supercharger?

if you cant get your hands back there, just do the bolt in the hole with the left front dog bone, just look at the dog bone you will see how it would hold the engine forward.

go get em

You have to remember that the 04+ GP's have more room in front of the firewall due to the V8 in the GXP models. Changing those back plugs is a lot easier in the 04+.

All done! Ended up taking the bolts of the motor side of the dog bones, putting a pry bar on the driver side engine lift bracket, prying foward then stuck a screwdriver in the dog bone in the sencond hole to hold the engine. The rest was pretty much done by feel. A few comments though.....buy new wires when doing your plugs because its extremely hard getting them off in one piece. I had to pinch the head of two of the wires with needle nose pliers, then with a long screwdriver pry on the pliers to pop the boots off. I also used a double swivle universle spark plug socket from snap on tools. There made for trans verse engines and worked well on all three plugs. Thanks for all the advice!!!

I dont know why u all had such a hard time with you back spark plugs. All I did was have my 6yo niece crawl up from underneath and stand on the sway bar, then BAM!
rear spark plugs changed! Only problem was I had to play "shoots & ladders" for an hour.

small children with the slightest mechanical ability's are a must!!!!

i still remember the kids when i was growing up, when they got a flat tire on their bikes, id be like i can fix that, and they would say no im not allowed, it has to go to the bike shop... are you kidding your parents would never know i fixed it, so off to the bike shop, for a close to a week, for a new tire and new tube, at 30 or 40 bucks when a tube repair kit cost 2 bucks.

my parents had no problem buying me the patch kit vs a trip to the drop off the bike, hell no "you broke it now fix it"!

Installed strut tower bar a week ago. Changed plugs Tuesday night... yeah, either need to remove the bar or strap the engine to get to the back (I strapped it). My forearm got stuck halfway in lol. I probably could have timed the plug change better.
