so im going to test drive an 06 lly today. its a 2500 4x4 108k, asking $28k (too high in my opinion) and i peeked inside and it had guages on the drivers side a pillar including a boost guage. that and the banks 6 gun tuner leads me to believe it might have been a semi dogged truck. nonetheless, im gonna take it on a test drive, partly to see if its a good truck to buy, partly as my continued research on getting my first diesel truck. what should i look for on the test drive? how do i determine if its been dogged or not, or will need injectors soon, or a tranny? there are alot of expensive parts to owning a diesel, and it has my feet a little tepid to dive in, especially on a chipped truck. what should i do and what should i look for?
06 lly test drive, what to look for?

First if it hasnt been run since night before pop hood and feel the upper radiator hose see if its hard. If its been run Check coolant. Check color. Once its idling, does it haze at idle. Its a lly, so u shouldn't have to worry about it but u could pull off oil cap when its running and see if theres blow bye. Then just the normal check the trans fluid and run the vin number see what it brings up. Go under and see how the conditon of the spin on filter. If its clean, probably been changed kinda recently which can be a good thing. When driving it, under decent throttle watch rpm when truck is shifting for flaring. And i always check to make sure the transfer case shifts smoothly thru all options with no odd noises.
Im sure there more i forgot but just a few i look at. Good luck.

Make sure the glow plug module recall/update was done. Other than that, everything that Arneson stated.
Sooo, I guess Checking out the injectors, cp3 pump and FPR is a waste of time???
Not to mention all the the control modules...
*sigh* Good god....no need to be sarcastic, but you could've just posted to check those, too. Arny had a pretty good list, and agreed with your tech 2 comment. My post agreed with that.
This is no longer the forum I joined 5 years ago....its damn sad.

NC, i didnt read anywhere where tom said your post was to be overlooked or wasnt important. Tom just stated another thing to check or look at, same as u and i did. Were all here to help out. :thumb:
I agree Tom.
Back on track.
Jasonsram, with the mileage I would check the front hub assemblies and the transfer case for pump rub.
To check the hub assemblies, jack the front up, grab the wheel at 12 and 6 and see if it moves... any play is bad.
For the t-case, slide under the truck and see if there is fluid on the back of the case.
Really? I have always been told that all 06 trucks came with an lbz. The ZF trucks had an lbz that had just been detuned to an lly because they couldn't keep clutches together. I guess I'm misinformed.
All 06 trucks produced before late September are LLYs (aka detuned LBZs). They have the 6 speed Allison and Bosch ECMs. I have one. All ZF trucks are LLYs through the entire year model run (last year for the manual, as I'm sure you know since you're looking for one). The Duramax used in the Van is also an LLY. So technically, the 06 LLY could have either an Allison, ZF-6 manual, or 4L85E mated to it. :thumb:
My bad, I guess having to deal with Ben constantly has made me be a tad bitter...
No harm no foul...:hug:
OP, first thing to figure out is if it's and LLZ or an LLY...
Not to thread jack, but
Is there a way to find out if this was done? 06 lly here aswell.
Sent from the drivers seat of an 06 dmax
Id look for another truck at that price. but for any dmax id look at the coolant tank
check wheel bearings, check the t-case, check u joints.
if it had a banks tuner it prob b safe, id prefer that over a efi tune.
look to see if it has the air intake changed, crankcase reroughted is there a aftermarket exhaust.
having efi scan tool would be handy
that way you can get a feel for how far the guy went.
wouldnt hurt to check the turbo shaft play.
