Injector replacement didn't solve my issue, thoughts?
Well, like the title says I'm pretty sure I've got an injector that is giving up on me.
Truck sounds like it's got a miss in the 1450-1650 range under torque, and boost was down 3-4psi. I dumped in some PS Diesel Kleen in the hopes of trying to limp myself home. Boost & power have come back, and miss isn't as sharp but still there.
Unilevers suggested manifold or turbo gasket or CAC leak, but using someTerm I overrode the turbo to 90% and couldn't find a leak. Now after the Diesel Kleen and boost returning to normal, I'm pretty sure it's a spark plug. It passed all tests in Insite, but that don't mean much. I've had leaky ones pass before.
I'm delivering tomorrow, then thinking of finding a place to park and change an injector in a parking lot. This is on a CM871.
I don't carry in the truck with me;
-injector leak tester
-inch pound dial torque wrench
-crows feet for torquing the lock nuts
-heel bar to pull injectors (but I do have a few pry bars)

Kinda thinking that I can make do with what I've got with me, except the dial torque wrench. Any suggestions where to get an inexpensive one just to do this and readjust everything when I get home?
Anything else I'm missing?

There's a Home Depot within walking distance of where I'm unloading to get a couple buckets for the coolant. I pack click type in/lb and ft/lb torque wrenches but I just don't think truck bounce and shaking would be very kind to the dial which is why I don't pack it. That and a guys just got to make choices in confined spaces.
Open to suggestions...

Edited to add: oh yeah, I'll get a turkey baster and Q-tips from Walmart next HD to clean the oil out of the head and bolt holes properly as well...

I appreciate the offer very much. One of the privileges I enjoy and share with the forum members.
I am unloading in Inglewood, CA. If you are anywhere near there, I'm happily take you or anyone else up on an offer like that. Just shoot me a PM.

Well, my shop is in Stony Plain, and the offer is open to you as well anytime.
I know exactly where said tank farm is, I've moved equipment in and out of there during construction.
Thank You!

I use a nail to pull my injectors and for the oil in the bolt holes I just screw the bolt by it self in to squeeze out the oil

RE: Parking lot injector replacement
I purchased this torque wrench for setting injectors. - It is every bit as accurate as the $250 one I have here, and now I use it instead.

RE: Parking lot injector replacement
The crow's foot and ladies slipper could be picked up at the Home Depot. Do you have 3/4 ratchet to bar the engine over? If so I'd say you'd be able to make do in a pinch. Don't know if you gonna pull both rockers or not. It can be done on an 870 without. I assume the 871 is the same. The real question is which one is bad? I don't recall seeing if you said you knew which was bad.
