Tahoe #8 Spark Plug access

[Roger08LTZ]

I've found this car quite easy to work on compared to others I've worked on in the past, but the #8 plug is a challange. Makes me wounder how many people over the years have paid for 8 plugs and actually got only 7. Once I pulled the inner liner it wasen't that bad actually. I used a long 3/8" Extension with a universal joint. Perhaps the pictures attached might help someone?

the GM FST trucks are not to bad. Usually #7 is the worst.

Go over to GM's MST Mid Size (Envoy, Trailblazer) with a v8.. I think the engineers were sodomites. 1, 2, 4, and 7 are miserable! #8 can be gotten the same way as you have above, albeit a bit tighter.

an Engineer is someone will walk over a thousand virgins just to screw a mechanic.

My 06 5.7 Hemi Jeep Grand Cherokee while the plugs are easy just about everything is a nightmare to work on! They run awesome until they don't. The Tahoe has a luxurious engine bay by comparison.

Put the spark plug socket on the spark plug and then use a shallow socket and ratchet to slide over the hex end of the spark plug socket and get it from the top of the motor

What did you do to your NBS GMT800 Tahoe/Yukon Today?

Ok, today, ordered a few things.. Got the level 3 Invincible trans 4L60E from Performabuilt, along with a 10.5" triple disc 2800 stall torque Converter.. Heads are the PRC "As cast" 225cc kit from Texas Speed, with stainless valves, new dual springs, titanium retainers, 212/218, .600"/.600", 112...

No need removing wheel fender, just remove the tire, use spark plug socket, plus regular 3/8 ratchet, and slightly bend A/C accumulator heat shield, the job can be done.

That’s what I did with thecopcar. That heat shield ate my hand up, but it’s doable.

I have a manifold bridge at #8 that I have to deal with before I can do the spark plug

What's the Manifold bridge? Something special about the 6.2?
