Why does my Vortec engine make a ticking noise when first started?
Keep in mind that heavier oils are slower to lubricate when the motor is first started, particularly on a cold start, which can lead to additional wear and tear on the engine. Running engine cleaner through the engine can help remove carbon deposits that can contribute to ticking at start-up.
What’s the misfire code on a 1998 Vortec?

Why does my Vortec valve lifter float when shut off?
Impact on the Engine Ticking lifters are not dangerous. The lifter is designed with a drain/fill hole that allows the lifter to float or fall based on oil pressure. An old trick is to run a thicker engine oil, which remains in the lifter longer after the engine is shut off.
What is the fuel pressure on a Vortec?
Dude, 150 psi of fuel pressure is extremely high, perhaps even impossible. I would suspect your pressure gauge. Dead head pressure may reach 100 psi. These vortec engines are well known for injector/poppet valve problems, so you may want to consider the upgraded injector assembly that eliminates the poppet valves.
Why does my Vortec 5300 feel sluggish when I accelerate?
I have noticed that when I accelerate it feels a bit sluggish. Have a KN intake system on it and keep it clean so I dont think that is it but I havent really done anything else as far as modifications. After accelerating it feels like it starts to let loose and eventually seems to get up to speed.

Why is my Silverado Sierra sluggish to accelerate?
Have a KN intake system on it and keep it clean so I dont think that is it but I havent really done anything else as far as modifications. After accelerating it feels like it starts to let loose and eventually seems to get up to speed. Any ideas of what I can do? Get a custom tune. I would get an exhaust of some sort to help with the tune.
