For those of you technicians out there getting confused by the instructions in the service procedures-cleanliness and pay attention to detail!
I'm gonna put this out there right now and I'm not trying to be harsh or critical for anyone who's taken this job on who is not in the professional automotive industry.
1. This job is not something that you will enjoy on the floor in your home garage; especially if it's AWD
2. I'm not making a step-by-step how to do everything, why? Because that's too time consuming and I think it is critical larger engine work like this is done by a trained, experienced, and well rounded technician. Too many chances for creating more problems if you are not experienced.
3. I will answer questions, but it's difficult for me to walk you through everything...this channel was designed and geared towards those who work on cars professionally...this procedure is not the difficult part of this job, TRUST ME.
4. GM (ACDELCO) PARTS ONLY!!! Replace all components, not some...ALL of it gets done or you're just wasting your time and will be in there again!!! Always replace the valve covers if heavy deposits! No shortcuts guy's...you do it right or like I said...you'll be doing it again!
5. Clean these engines from top to bottom using brake cleaner. Blow everything out thoroughly to include oil passages with compressed air. Clean valves using carb cleaner and compressed air. Be sure you get the inside of your oil pan too...if she's a disaster when you open her up...remove the oil pan to ensure you get it cleaned out. You're not going to hurt the engine doing this as long as you change the oil twice after you button her up. The rest will evaporate and burn out through PCV...Done hundreds of them this way and they are solid afterwards!
The other thing that other video's are failing to tell you is those phasers/actuators should be replaced everytime you do a chain job, you're just shooting yourself in the foot if you don't!
Also, the Intake PHASERS/ACTUATORS are different from one another from bank to bank, they're clocked different...also very important to know. However, the EXHAUST PHASERS/ACTUATORS are interchangable.
Use only OEM ACDelco parts, stay away from aftermarket trash, PERIOD!
If you want to try and accomplish this without doing it in two stages as some will claim is easier or possible with specific tools...well have fun, because you'll be hating life going in a second time. I am merely prewarning you...take it or leave it. YOU DO NOT NEED SPECIAL CAM HOLDING TOOLS FOR THIS JOB!!!
Many people screw this job up, because they're trying to take shortcuts-pure and simple! If you can't time this engine IAW Service Information then it's definitely beyond your skill level in numerous ways, not trying to be critical, but it's common sense. GM says this is how you time it; so why are we even debating whether or not it can be done another way. Everyone that's having trouble with it is NOT FOLLOWING PROCEEDURES, GEEEEE...I WONDER WHY 🤔?
Yes there's TSB's out there for the CKP reluctor wheel actually shifting and causing CMP/CKP correlation DTC's and the best way to rule that out is to physically check for this by removing the oil pan and measuring for it! I'll link a great page explaining how to do this below. If you're worried about that as a possibility it is only beneficial to remove oil pan regardless to clean out any deposits in the pan!
