    Anyone have experience with gmt800 trucks?

    "I cant figure out what could cause this damage but never leave any other evidence. The grille was fine, there is no paint or evidence of an animals remains, there was no dirt or rock particles." Could it have been driven into a pile of snow/ditch and the resulting packed in snow didn't damage...

    Brake pedal goes to the floor after new shoes

    do your drums have a "lip" (where the pad has not worn down the drum) on the outside, or were they machined? If there is a lip on the outer side of the drum they will feel tight but are actually not ajusted as your new pads are only contacting about 5% of the drum surface (contacting the lip only).

    Help Passing Emissions Z71

    Looks to me like the EGR Supply/Vacuum tube is cut/broken. I had to zoom into the picture to see it.

    Replacement Brake Drums

    I bought a truck with a bad brake shudder. It turned out it had a bent axle, which on my 98 2WD really threw the drum around. I could visibly see it with the rear wheels on stands.

    No-Start Vortec 350

    Have you done an actual compression test on all cylinders? If the valve lash is not set properly then it may pop and sputter but not start.

    Serpentine belt thrown twice on a 1988 C1500 5.7 350 Silverado

    Makes sense... much more sense than my reason for running the A/C in DEF during the off season....

    Serpentine belt thrown twice on a 1988 C1500 5.7 350 Silverado

    depends if your system was set to "DEF". In my understanding, when "Defrost" setting is selected the compressor still turns on to keep things lubricated in the off season. But it sounds to me like it was concluded your tensioner went bad... a bad tensioner will throw a belt in my experience...

    Replacing part of an axle tube.

    I think we've all been there and had that kind of day. At least you didn't walk out from lowes after forgetting your wallet and find out your vehicle was stolen...

    1997 5.7 Vortec Engine Knock/Tap

    I'd look into the flex plate first... I believe somebody said it was possible to unbolt the torque converter from the flex plate, slide the TC back to the rear of the trans (with a prybar, all you need is about 1/8 of an inch clearance) and then you should be able to start the engine and see if...

    1997 5.7 Vortec Engine Knock/Tap

    Is this what a cracked flywheel sounds like? (Given his comment above about unloading the flywheel by moving the Trans between P & R)

    1996 Chevy C 1500 vortec 5.7 Rotor and Hub question

    So yes, they just used "stock" (but wrong) pictures. I've experienced the same thing ordering off Amazon etc.

    1995 GMC C1500 engine cuts out then takes a few minutes to start. Pulling my hair out!

    Or if you happen to have a smart phone you can set up your test plug and take a video of what you see. That seems only a little less work than riding around with a friend all the time.

    1995 GMC C1500 engine cuts out then takes a few minutes to start. Pulling my hair out!

    I'd want to check for spark (easy enough to do on the side of the road) the next time it quits. spark/no spark is a diagnostic fork in the road, helping you eliminate a lot of unnecessary work.

    overheated in -20 weather

    I'd want to test your antifreeze... sometimes after a lot of boil overs/add water etc trying to figure out a cooling problem I end up with too much water and not enough anitifreeze. I had a vehicle boil over once because of that. Turns out the Radiator was full of slush and the block was so...

    LOUD rattle when engine starts

    I keep coming back to your comment in the original post: "It doesn’t do it when the starters engaged (I pulled the fuel pump relay and it didn’t do it the whole time, just when it was idling)" The reason for the lack of noise when not firing but just cranking is still unexplained... if it...

    Help! '99 Tahoe doesn't start...

    Fuel pressure may be too low. See if it tries to start with a little (just a little) shot of quick start.

    distributor - '98 K2500 5.7L Vortec

    CMP offest can be set without the use of a scanner several ways. The most interesting to me is the person (I believe on this site) who talked about rotating the dizzy slightly and seeing how quickly it throws a code. If the code comes quicker than the previous time, (measured in seconds) then...

    If this is actually about CMP offset not being able to be adjusted within range, for more info on what Shurkey says above check out this video from 12:30 onward.

    distributor - '98 K2500 5.7L Vortec

    are you reading cam/crank offset or timing? They are not the same thing. The fact that you list 25 degrees and not + (value) or - (value) makes me thing you are reading and reporting on ignition timing. Ignition timing is completely set by the computer. You can only adjust the cam/crank...

    Brake bleeding issues

    With the cost of machine work out here (if you can even find somebody to machine a drum properly) and the cost of new drums... those drums were already "junk" :-)

    Brake bleeding issues

    "I'm kinda mystified why the rear brakes can go out-of-adjustment that fast." I'm curious if somewhere along the way, somebody installed new brake linings but used the old unmachined drums (leaving them with a lip). In that case, when the rear brakes were put together and adjusted, the brakes...

    LCAs hitting spindles.

    Are you missing a bump stop? Or a different size bump stop?
