  1. I bought my truck, a 2002 silverado extended cab z71 , in October with 56,000 miles on it. It has developed a clunking sound from the middle of the truck to the rear of the trunk some where under the body. At first I thought it was the crossmember or transmission mount but not a thing... It only happens on rough roads and doesn't seem to happen at speed. I feel it on the floorboard(at least I think I do). Any ideas?
  2. Out of curiosity did it work by just plugging it in? I wouldn't mind having one of those myself...
  3. That would be nice. I sometimes miss my 2017 tacoma and it's little features, but it drove like ass. Sad that a 16 year old truck drives better than a new one. Toyota really dropped the ball on it.
  4. Sweet truck! 14:1 is crazy. That must be a quick little truck. I ran a 7.3 in the 1/8 but my car was pinging like crazy with only 10:1! Sadly, no more drag strips near me, so no more racing so I am switching it over to a manual!
  5. You should be able to reset the engine hours meter anyway I think. I remember my dad's 05 you could because we would reset it to see how much time the engine was on when we went off roading/hunting as more of a novelty. My 2002 doesn't have any of those features, I sometimes wish it did because I like to gather data like that for whatever reason.
  6. Camshaft

    I have been looking for a graph. Interesting curve.
  7. Camshaft

    high-lift won't cause torque to go down ever. Those cams are so different that they cannot be compared. Remember the goal is to get air into the engine. If you open the valve farther, it is going to allow more air(unless you're beyond max flow of the head), valve timing is where you play with the power curve. Open the valve for longer, the curve goes higher. So your goal is to open the valve as far as you can for a shorter amount of time.
  8. Camshaft

    Why would he keep lift down? He needs as much lift with as little duration as he can get--I would keep it around .550 to keep it reliable.

    Headers/exhaust will also make it sound and drive better, and stick with a smaller cam. The truck is too heavy to really take advantage of a large cam.
  10. Brakes

    Try the test, if the brakes seem the same, you might have a leaking booster which means your engine essentially has a HUGE vacuum leak when you depress the pedal
  11. Brakes

    Sounds like you might have a leaky booster or a leaky booster hose. Check them, it sounds vacuum related since the engine bogs.
  12. heck it should! I went from carb(stinky) to a MPFI on my big block and it is MUCH cleaner all the way around. The carb would idle at around 12.8:1(any leaner and it would die) where the MPFI will idle at 13.9:1 all day and doesn't really smell up the garage
  13. Can’t get 4x4 to Work

    Sounds like the front hubs aren't engaging. Are you sure someone didn't convert it to a manual hub lock?
  14. Rust on 2013 Silverado

    Toyota is really the only one with frame rust issues. The chevy won't really have a problem with frame rust.. Mostly brake line and fuel line rust. Honestly it is probably surface rust and maybe some pits. I just bought a 2002 silverado with frame rust and it's mostly just surface rust. It has resided here in Alaska for its whole life. Honestly if you're worried about it, just get a wire brush or something to get anything that is loose and then apply a barrier film or something. Truck looks great! I have had a 2014, 2015 and a 2017 tacoma.. Yes stupid I know. The 14 was a 2wd 4cylinder so I got rid of it for the 15 for a 4 cylinder 4wd.. Loved that truck and thought if the 4 cylinder is this good, the 6 cylinder must be better! yeah toyota REALLY dropped the ball on he 3rd gen v6 set up. I hated it so much that I went and bought an old 2002 chevy. I haven't been happier. Literally the only thing I miss from the tacoma was the backup camera. Then reading all the frame rot through issues, I am happy now. I have already put 2k miles on the chevy this month. Hasn't skipped a beat. Only annoying thing I found was the rear knock sound over an incline which is a known issue that I know doesn't hurt anything
  15. Luckily we don't use much salt up here, mostly sand. Not much rust though the truck looks relatively new underneath
