    Huge problems :( Engine maybe

    Thanks Jim! Much better description. :thumbsup::thumbsup: A bad cylinder will show no change in the idle as you loosen the fitting. A good cylinder will make the idle worse as it drops out. Right. IIRC the wrench for the injector body is 1 1/16". Been a while since I changed mine, so I...

    Huge problems :( Engine maybe

    The last time I ran into a stuck injector was on a Jetta turbodiesel. The knock was loud enuff to make me think a rod was about to come out the pan. Scared the crap outta me! You mentioned that the engine idles like it's running on only 7 cylinders. You also mention that time (and $$) are...

    had a bad day today!!

    Sorry to hear that. It'll be a tough Christmas without him. Treasure the good memories - they're the greatest legacy you can hand down to your children. God bless you. Dave

    rocker arms

    Torque on the rocker arm bolts is 40lb/ft. Try turning the engine over by hand 1/2 turn. Check the rockers for 'looseness'. Turn the engine another 1/2 turn. Check again. Do this 4 times (720 degrees). You should notice that all 8 rocker arms wiggle a small bit at some point. This is...

    Dumb move on my part

    Nope. As you've heard form others, our gauges are famous for being inaccurate. As I discovered this weekend in OKC, doing some emergency cooling system repairs, my temp gauge reads 20 degrees low! Driving thru the Arbuckle Mountains on the way up from Tyler, TX, my alternator decided to dive...

    I am soooo jealous! You're seeing about 30% better mpg than me, and you're in a heavier truck!!:eek: :D :D :D Went well. It's great to see family, and I like being able to do things for mom & dad (they're in their 80's). Got all the Christmas decorations up. Thank heavens they just do...

    Diff gear ratio suggestions

    Invested in the GMTDScan program from Stefan Enghe. Definitely worthwhile! Got my pump timing set and the TDCO is spot on at -1.94. A little clanky in the morning, but I sure enjoy the way it runs. :D I need to pop the diff cover and count gear teeth. One of the things I've wondered...

    Dave - Looks like you have the same drivetrain setup I do - 4L80, 4.10 gears and 235/85's. What do you get for mpg? I'm considering a swap to 3.73's. That would be approx 10% reduction in rpm. If my math's correct, I'd be looking at 2250rpm at 65mph. I kinda figure I'd see around 1.5mpg...

    Wow, that's impressive! A 10.5" full floater on a half-ton vehicle. I didn't realize they were that heavy duty!

    Harmonic Balancer / Crank Pulley

    As long as you're in there, I'd spend the extra $100 and take care of any future/pending problem. Specially when you consider that the noise & vibration that you felt thru flexible engine mounts is a small percentage of what's happening down on the motor. Your harmonic balancer has had its...

    For step-by-step DIY info on DRAC recalibration, go here: http://www.tbichips.com/drac/#ratio%20rpo I'm ready to tackle mine. Problem is, when I changed out the dash, it got buried. Now I gotta remember where I stashed it in all of those harnesses!

    Diff gear ratio suggestions

    That sounds mighty attractive! I might hafta reorganize my priorities and apply the No-Slip diff $$$ towards an ATT! ):h I realize that your results won't directly transfer over to my setup - I've probably got easily 1000# on you. Even so, it's still be worth trying. I think the first...

    Overton is south of Longview and east of Tyler. Take 59 south to I20, then go west to the Liberty City/FM3053 exit. Head south 16 miles and you'll be in beautiful downtown Overton, pop 2310. Thanks for the cruise info. Sounds like the 'sweet spot' for the 6.5 is around 2100rpm. That's...

    DD - Thanks for the input on rpm/speed. 2500 at 65mph is exactly what I see, so it looks like I've still got the stock 4.10 R&P. Tim - 18K is more than I ever plan on towing. Most of what I'll be doing involves loading equipment/stuff into the back and carting it around. Although I can...
