There it is.  That oil is not Dexos rated.  I never thought the wrong oils could damage engine components until I became members of these various forums. 

 

Those GM standards are to ensure the proper functioning of VVT and AFM.  It's not like the old days when oil just helped to shed heat and lubricated bearings.  Now it does work too.

So if this is the case, what parts are broken due to the oil? The parts have been replaced and immediately the codes come back. What part of that system continues to be malfunctioning? If I were to change oil, what parts would need to then be replaced?

I don't know Zack, start running the right oil and see if things work themselves out.

 

The oil you are using is not up to doing the work required to operate the VVT system properly.  Changing the oil a time or two ought to get things working right again.

 

I run ACDelco oil in my trucks with great results.  We also started using Quaker State full synthetic, which we can buy at Walmart, in one of the trucks to test it out.  So far so good.  I'll do an oil analysis after the third oil change to compare it to the ACDelco oil.

Just an update, changed the oil with dexos rated oil. No change. Not sure if Im supposed to go back and replace all the same parts for a third time or not. I think Im giving up. The truck drives fine and Im not going to dump money into the same parts over and over.

I have the same problems as you have. I have changed the same parts as you except fuel pump and harness as I like you couldn't find one.

 

Tried with a bottle of Rislone last weekend before changing oil and filter. It was actually OK for three days!!!, then it came back. The latest thing I heard of is that the cambearings are bad. And someone asked me if I had a crank/cam relearn done. I have not, but I never heard of anyone having to do that.

Does anyone know if that has to be done??.

My roommate's truck is doing this now.I have the proper scan tool and I plan to do the relearn as soon as he gets home. I will try to keep everyone updated if that helps he is having other codes though also, and i'm not sure if it's going to help. 

 

Here is a list of ALL codes. Some may be irrelevant. 
Timing: P0011, P0016, P0018, P0021

Misfire: P0300

Fuel system: P0171, P2635

U0401, U0401:71

C0755:03

 

 

I am a certified mechanic by the way. But I only have a few years of experience in shop

That would be really helpful for me to know.

Mine has actually got a tiny little bit better lately,the lights goes away by itself without me doing anything. It comes straight back again as soon as I lower the speed though😕.

But it's kind of an improvement.

Next step i plan to do is to find a way to do a relearn procedure and maybe get a new AC-delco sensor and change the one non original I put in there, don't remember what brand, but not AC-delco.

 

Looking forward to your results.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
