I am hate to even say it but, really truly, I put a 27 mm craftsmen deep impact socket on the end of a 1/2" impact gun for both removal and installation. Torque them the same as I do a wheel; run it down and 2 bumps of the trigger after.. Probably 100-120 ft/lbs.

100- 120 ft /lbs on injectors with an impact gun? You like to live dangerously?

He just hasn't seen the head fracture when he is doing it that way yet. I do them by hand and still had the injector boss let go. Could have been weakened by the PO however. Got to watch that towards the head pressure.
What is stock torque? Like 90 ft lbs?

probably slightly more dangerous than me using my $10 harbor freight torque wrench to measure the recommended 52ft/lbs...

If you think your HF torque wrench is that far off, you can do a rough calibration with a 10 lb weight and a 5 ft pipe and set the torque wrench to 50 ft lbs and see if it clicks.

After torquing to 52,and having a few fall back out, and then reading about the breaking point of the boss area, I decided that it was the worker, and that the impact gun would not out as much erroneous pressure in strange directions.

I think I use that same socket, it works if you keep it straight and level. I've tweaked a couple hose fittings before I learned to be careful.
I always meant to slot the sides of it but never remember till I need it.
Never broke anything else, no air gun though.

My HF torque wrench was within 1% of the Snap on one till it launched it's head through the woods.
Haven't had the new one tested as it just sits in the box in case I break my nice one.
How do the injectors all out? the crush on the heat shield should lock them in place. I've never seen it, always use clean threads and anti'seize.

The Lowes Kobalt 1-1/16 12 point deep socket has a lot of wiggle room for the nipples. Still, I usually put a short piece pf 1/8 hose on the nipples to protect them from getting nicked.
I also have a 27 mm 6 point deep impact socket. It fits all the injectors except one by the IP. Can't rememember if it's #1 or #2, where I have to undo something on the IP to get the impact socket on the injector. The Lowes Kobalt 1-1/16 12 point deep socket does not have this problem.

Well they came out ok, I didnt torque them back in, more like did them up tight sparkplug style.
one of my main issues was getting to number 2 injector and I wish I had one of those wobble drive extensions as previously mentioned.
one of my injectors looked a bit wet, like it could be a dribbler, my spare set looked pretty dam clean, shame it runs like a bag of bolts! Back to the drawing board!

If you don't tighten them enough to bend the heat shields , you will have trouble.

You can feel when the heatshields compress... it doesn't take much torque. "Sparkplug-tight" is about how I do my injectors (rarely with a torque-wrench). Copper anti-seize on the threads works a treat.
Slipping the IP & pulley back a tooth can make the injectors and GPs easier to deal with.
