Re: Engine noise 2000 Tahoe 5.3
How long did you guys let the engine run after you heard the noise? I worked at the GM dealer for years and have worked on hundreds of the 4.8, 5.3, 6.0, etc... I have heard these things knock so bad you would think the engine was destroyed and it was just piston slap and would go away once warmed up. Seemed to happen alot worse in cold temps.
