2006 Silverado Internal Engine Problem

I am a contractor and purchased four 2006 chevy silverados. One has 70,000 miles and smaller v8 engine. Recently the engine bay produced a ticking noise and when hood was raised it seemed to becoming from the belt and pulley area. Even my mechanic thought it was a bent or warped idle pulley (little pulley I guess that does nothing). Anyway upon further investigation my mechanic could not figure out the problem, the chech engine was on but registered as a misfire but had been cleared. He says it is internal problem that can not be diagnosed with out opening up the engine, He recommended I take to the dealership for diagnosis. Then it occurred to me, my driveway is a step 45 degree incline that I back into. I remotely start the truck every morning to warm it. Could this cause a ticking or internal problem because oil pump not getting oil etc? Need some advice thanks.

Well, i know that a clicking can be produced when the vehicle does not have enought oil, or needs some engine restore oil. Try some Lucas Engine restore oil, and mix it with some other brand, it is thick. 
Another experience i had with a knocking noise is that there is a heat shield in some vehicles, and mine used to radle against the engine. I just bent it a little to stop the knocking.
If this doesnt work, i know a few more things that could cause that noise, but start out with these 2 things because if it is something internaly like a thrown push rod, you will need to fork out some serious cash, those engines are not cheap.

My oil gauge for my 2006 Chevy silverado v8, 2wd does not work. It reads 0 pressure and stays until at a stop and radically jumps.

Sounds like you need to replace the oil pressure sending unit. Should be located on the engine down by the oil filter.

Have a 1995 Chevy Silverado K1500, 70,000 miles, reverse is slipping. Forward is fine.

You can try a product like transmedic and changing out the filter and fluid. If that does not work then you will have to rebuild or replace the transmission. Good luck. Dont forget to rate.

The stepping motors in the gauges go bad. do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options. The dealer charges around $300.00. It will continue to worsen.
