  1. Camshaft replacement

    Ok thanks for the replies. I guess I will just get a stock replacement because I don’t want to mess with tuning at all Sent from my iPhone using Tapatalk
  2. I am replacing the camshaft and lifters on a 2007 Silverado 2500HD with the LQ4 6.0 engine due to a slightly chewed up lifter. Who makes the best mild performance cam for these engines? I do not want to do upgraded valve springs or pushrods or change the tuning in any way. The truck is only used to pull a 1 horse trailer, not looking for anything crazy Suggestions?

  3. Cummins 6.7 to GM 6.0

    I will say, I do miss how fast a gas engine warms up. That’s about the only thing I miss. I used to have an 01 Silverado with the 6.0 and a 97 jetta with a 2.0 gas engine. I have since upgraded to an 00 7.3 powerstroke and 99 jetta TDI. Overall I am very happy with my diesels, my tdi is yielding almost double the mpg that my 2.0 did. (25 vs 45-50) gas engines are definitely better for short trips. I feel bad starting up my diesels in the dead of winter and putting all that wear and tear on them just going to the store or something or something short. To each his own. Glad it worked out for you[emoji106][emoji2534] Sent from my iPhone using Tapatalk
  4. The upstream o2 sensors send info to the PCM so it knows how to adjust how much fuel goes in and the downstream ones are only used to monitor the cat. You could try to replace the downstream one, but the cat could be clogged. These cats generally don’t fail unless the truck has been running with a severe misfire for a good amount of time Sent from my iPhone using Tapatalk
  5. Yep those bolts just hold the heat shield on. Most of mine came out ok but if they break it’s not the end of the world. You really only need 2 bolts to hold them on. And if all of them break you can just run without a heat shield, lots of people do and it doesn’t hurt anything Sent from my iPhone using Tapatalk
  6. Are you sure the oil gauge isn’t just messing up? Gauge clusters/individual gauges failing are very common on these chevys. Have someone monitor the oil pressure on a scanner and compare it to what the gauge says. If it reads the same, you’ve isolated it to the oil pressure sensor or an actual oil pressure problem These oil pumps can fail by way of the bypass valve sticking open. This is a valve that is used to bleed off excess oil pressure if or when the engine is making too much, at high rpm for instance. It can get stuck open and not allow the pump to make any pressure. This doesn’t sound like your problem though, just a thought Sent from my iPhone using Tapatalk
  7. I'm not sure what you're using to scan, but to look at the fuel trims you'll need a good scanner that can show you live data Sent from my iPhone using Tapatalk
  8. The upstream o2 sensors are the only ones that will affect fuel trims. The downstream ones only monitor the catalytic converter. If you're having a fuel trim issue across a whole bank, it's either an upstream o2 sensor or intake manifold gaskets Sent from my iPhone using Tapatalk
  9. LBZ reliability

    The only downside to the L5P so far is that they can't be tuned, and therefore can't be deleted. Also, I'm not super familiar with the Cummins engines, but I am friends with the guys at a local diesel shop and they said the 6.7 cummins are known to blow head gaskets. They said the 6.7 is basically a bored out 5.9 block, therefore the gap between the cylinders is very small. Even with head studs they like to blow. The heads need to be o ringed and some guys even tap out the block to get thicker head studs in to lock the headgaskets down Sent from my iPhone using Tapatalk
  10. LBZ reliability

    Without double checking, I believe the 2008 was the LMM, not the LBZ. You wanna stay away from that, they were the first duramaxs equipped with a DPF, which is the big bad guy in diesel emission controls. Also GM went bankrupt around that time, so they cheaped out on a lot of stuff. The LBZ was 06 & 07. The later 07 model LBZs are good motors. The older LB7s and LLYs aren't so good, the LB7s are known to go through injectors and the LLYs are known to go through head gaskets. Sent from my iPhone using Tapatalk
  11. I can't stand newer vehicles that "slip" gears rather than downshift. I like to be in a gear, know I'm in a gear, and pull that gear. Then go to the next. As it should be Sent from my iPhone using Tapatalk
  12. As said, it has 4 forward gears and a torque converter lockup that comes in around 45 mph, which feels like a 5th gear to someone who doesn't know what's going on. 4th gear is overdrive, but also as said I think it depends on your diff ratio whether or not it is actually a true "overdrive" Sent from my iPhone using Tapatalk
  13. My 2000 Chevrolet Silverado 2500

    If you're deleting the cats, get a magnaflow 12909 muffler, or maybe one slightly shorter if you want more noise. I had the 12909 on mine w/out cats and it gave a great tone, not loud at all, but very aggressive. Friendly to the ear Sent from my iPhone using Tapatalk
  14. 02' 2500 With P0440/P0449

    I can't offer any help on the codes, but if you do have to get at the tank, pull the bed off and let the tank where it is. It's much easier that way Sent from my iPhone using Tapatalk
  15. Fuel Pump Part Number

    Not sure if you've done this before or not, but I highly recommend removing the bed vs dropping the tank Sent from my iPhone using Tapatalk
