I'm a New Guy, I have a 06 Avalanche 4X4 with the 5.3 flex engine. I got lifter noise, did all the cleaning tricks got no joy. Now I'm ready to replace the pick up tube O ring and while there the oil pump and timing chain and sprockets. Does anyone here have any experience with this? I have a Haynes book; I got it up on stands and I removed the L/H tire today. Tomorrow it's the stone shield under the oil pan, brake caliper, rotor, and hub I hope. I have to pull the inner axle and axle tube, some miscellaneous stuff under the engine, the radiator, water pump. I have the parts, new timing gear cover, oil pick up tube w/new o rings, timing chain set, will get a new water pump too. If any want to help you need to live in the South Puget Sound area in S. Kitsap County! I'm Disabled Vet getting older and it's hard for me to do this work anymore. I used to be a Vehicle Maintenance mechanic in the USAF so I know what I'm doing, but things ain't what they used to be.
