I have a couple questions. First, I know there's a valve adjust DIY somewhere here but, I can't find it, would someone happen to have the link ?

Not having done it on my truck before, I'm not so sure of any easier way to rotate the crank without removing the fan shroud. Between the dual CP3 and a Fluidampr which is thicker than the stocker, I don't see an easy way in. Because of the Fluidampr being thicker, there's not a lot of room to get to the crank bolts underneath either.

Am I going about it wrong ? Also, I haven't looked yet but, does the Fluidampr have timing marks ? If it doesn't, what's the best way to find TDC ?

Don't have the link to it, but I copied and pasted a while back and saved it.

valve adjustment

gota say.. i dont know why i waited so long to do it..
45 min start to finish..

tools.
10 mm for cover bolts
9/16 and a 5mm allen wrench for the adjustments
15mm on a long 1/2 drive to turn the motor over..

140k on the clock, mine were LOOSE!
recomended specs are .010/. 020
int tolerance .006/.014
exhaust tolerance .016/.024
i set mine .008/.018

STANDARD PROCEDURE - VALVE LASH
ADJUSTMENT AND VERIFICATION
NOTE: To obtain accurate readings, valve lash measurements
AND adjustments should only be performed
when the engine coolant temperature is less
than 60° C (140° F).
The 24–valve overhead system is a “low-maintenance”
design. Routine adjustments are no longer
necessary, however, measurement should still take
place when trouble-shooting performance problems,
or upon completion of a repair that includes removal
and installation of the valve train components or
injectors.
(1) Disconnect battery negative cables.
(2) Remove cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
(3) Using the crankshaft barring tool #7471–B,
rotate crankshaft to align damper TDC mark to
12:00 o’clock position.
(a) If both number one cylinder rocker levers are
loose, continue to next step.
(b) If both number one clylinder rocker levers
are not loose, rotate crankshaft 360 degrees.
(4) With the engine in this position, valve lash can
be measured at the following rocker arms: INTAKE
1–2–4 / EXHAUST 1–3–5. Measure the valve lash by
inserting a feeler gauge between the rocker arm
socket and crosshead (Fig. 32). Refer to VALVE
LASH LIMIT CHART for the correct specifications. If
the measurement falls within the limits, adjustment/
resetting is not necessary. If measurement
finds the lash outside of the limits, adjustment/resetting

is
required.
VALVE LASH LIMIT CHART
INTAKE EXHAUST
0.152 mm ( 0.006 in.)
MIN.
0.381 mm (0.015 in.)
MIN.
0.381 mm (0.015 in.)
MAX.
0.762 mm (0.030 in.)
MAX.
note:
If measured valve lash falls within these
specifications, no adjustment/reset is necessary.
Engine operation within these ranges has no adverse
affect on performance, emissions, fuel economy or
level of engine noise.
(5) If adjustment/resetting is required, loosen the
lock nut on rocker arms and turn the adjusting screw
until the desired lash is obtained:
²


INTAKE 0.254 mm (0.010 in.)
²


EXHAUST 0.508 mm (0.020 in.) Tighten the
lock nut to 24 Nm (18 ft. lbs.) and re-check the valve
lash.
(6) Using the crankshaft barring tool, rotate the
crankshaft


one revolution (360°) to align the
damper TDC mark to the 12 o’clock position.
(7) With the engine in this position, valve lash can
be measured at the remaining rocker arms: INTAKE
3–5–6 / EXHAUST 2–4–6. Use the same method as
above for determining whether adjustment is necessary,
and adjust those that are found to be outside of
the limits.
(8) Install the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION).
(9) Connect the battery negative cables.

thanks. I have the manual but I thought for sure there was a pictorial DIY done here by someone.

just did mine this afternoon on my truck was a little close to being out of spec was not to hard took me about an 1hr didn't rush anything and triple checked my lash. Easiest way to turn engine over is by turning the alt. nut counter clockwise. Engine turns over pretty easy

Without the barring tool, open the inspection cover on the front of the housing (may be Bell I dont know not a mechanic but its the cover when you open you can see the Flexplate and the front of the converter) you can put a screw driver in the teeth of the flex and rotate her over. And man is the TDC hard to see or what, man thay could have made the line thicker,or the letters a different cover. Anyhow remember when you are at the TDC mark you may be at BDC so you need to see if #1 intake an exhaust are tight or loose that will tell you, then lash from their.

Didn't think of that... thanks. Doing things by yourself making things like that harder but, if the Alt doesn't work, I'll get it done that way :-)

I don't know if the Fluidampr even has timing marks. You would think it does but on a quick look, I didn't see any.

tritont......be sure to note that the specs for your truck are .010 intake / .026 exhaust (as of the 2006 model year).

couldnt have said it better my self....

When you do find the TDC make sure its at true TDC not 180 out. The TDC mark will be present at both settings (true TDC and 180).
You can tell your at true TDC when the mark is in the upright position and you can read the lash on the #1 Intake and #1 exhaust.

Get a barring tool......

On the fan shroud remove the retaining nuts that hold it to the engine. Then you can push it back enough to get in there and get to the crank bolts.
Just remember to use the right tools it might take a while to find ratchets and sockets that fit correctly. Take your time!!

Everyones getting real good at cutting and pasting around here......
