So I have an 09 Silverado Hybrid with Alum 6.0l LSM Engine. I'm wondering if I disable the DOD using HP Tuners, would the VLOM plug still be required? So my question is really this. If you disable the DOD in the ECU, then what is the purpose of the plug after that? Could I just disable the DOD in the ECU as "Preventive Maintenance"to keep the issue from ever occurring? Truth be told, mine already has the lifter issue, and hopefully I can get it to release, but with this truck being a hybrid, getting access to ANYTHING on the passengers side is a nightmare. There's NO room at all. Even getting the spark plug wires off the coil packs is a complete bitch. I just want to get it running again, ensure the issue don't come back, and sell it. I don't have A lot of time, and don't fully understand why the plug needs to be there if DOD is turned off???
Thanks

Nevermind. That hole is plugged on the back of the hybrid intake. But NEW problem. I replaced all the AFM lifters on the side that was bad, just put it back together and one of my lifters is ticking like crazy.. Even with fresh clean 5w30 and running for 20mins it still clicks so its apparently not pumping up. it runs fine, but just makes noise. Is there something im missing with these lifters that I need to do? I'm going to pull the valve cover back off and retorque all the rockers but I did them all at 22lbs when on the low side of the cam, so they should be good.
Probably just my BAD luck... One of the new lifters is bad. Oil PSIs are showing around 60psi at idle, and 80psi when i rev the engine up now... The 40psi before must have been because the little filter under the sensor was clogged completely...
