Oil Pump Problems of Chevrolet Tahoe

I bought my chevy Tahoe in 2012. I would changed my oil every 3000 miles. Every time my oil was changed,the oil tech would inform me that your oil is very low by showing me the dip stick. When I had 167,009 miles,I was experiencing lifter noise and oil consumption. I took my Tahoe to a chevy dealership were they found ehaust lifters and cam lobe was worn. They had to replace camshaft,lifters,oil pump,bolts,gaskets,etc. Very expensive fix. Now that,I have my 5. 3 vortex motor fixed,it still consuming oil. I have had many oil changes since motor was repaired and still my 5. 3 vortex motor is consuming oil showing low on oil dip stick. On 12/5/2020,I had a oil change at a oil change place and the technician showed me the dipstick with the oil showing very low. Where is this oil going?.

My issues started almost two years ago when dropping my child off at daycare. I was on the highway and noticed a loud ticking noise coming from the engine. At first I was not sure what it was until I pulled in the daycare and it was evident something was wrong. At that point the stablitrak and traction control light started flashing. I had to have the vehicle towed because I tried to move it and when I put it in gear it jerked so hard I was scared the engine blew. I took it to the certified chevy mechanic, cylinder 6 misfire. We replaced the plugs, coil packs etc, trying to see what the issue could be. He finally replaced all 16 lifters, cam, head gaskets and oil pump as well. Once he got it together, it was still a misfire on cylinder 6. He took it apart to look at the pistons, they were fine. The top of the motor he practically everything brand new on it. The chevy dealership are aware of the lifter issues with this vehicle and blatantly told me, I need a new engine or could purchase a new vehicle. Still no resolve as of June 23, 2020! please issue a recall on this as so many of these vehicles have this issue and it's not fair to us that they designed the engine so poorly.

While driving 35 mph to a family function the low oil pressure light came on. The pressure gauge then started changing from 0-80 continously. After google search I found that I should pull over and turn off the engine. I took it to an independent mechanic where he checked the oil and it had the righ amount of oil and he stated that the oil looked good. I take my truck regularly for oil changes and my last one was may 1. 2015. The mechanic told me that it may be the oil pump so we replaced it. The cost for the service was $200. It is now only a few days later and the oil pressure gaige is still going from 0-80.

Engine knocks when it started after sitting for a while untill oil pump picks up. I personally know of five other 5. 3 liter v8s that have the same problem,but my dealership has never heard of this . I find this hard to believe. A friend told me that there was a TSB reguarding a check valve of some kind that would stop this.
