05 Silverado 5.3 engine noise

My silverado has 70k miles on it. I've been noticing within the last few months a knocking noise coming from engine. The engine oil gets changed regularly, and I don't notice any lost performance. It sounds like a rod bearing. Does anyone know of the same problem with these 5.3 liter engines?

I've changed my engine mounts 3 times on my 2004 A4 cabreolet and they fail within miles(start to vibrate & then within a week, severe knocking) the 2nd time, also changed the ****** mount, 3r


Engine mounts do not go bad in five miles. Sounds like you're treating a symptom and not the cause of a more serious issue. Are you sure all cylinders are firing correctly? That the severe knocking is not coming from your engine internals? Have you checked the steel around the engine mounting points for cracks or other damage? And just in case, if the mounts you are using are poly, are you lubing them before installation?

Check engine light went on on my 2005 chevy silverado @ 102,000 miles. Never had an issue before. But I noticed that it has been knocking lately for about 15,000 miles. Mechanic friend said not to worry,...


Hi, it could be a wiring issue. I would check for a broken connection or bare wire shorting to ground. Usually though, when the computer loses the knock sensor signal, it will ****** the timing to a safe range that will not allow the engine to knock. If you tell me which engine you have, I can give you more specific troubleshooting steps, such as the reference voltage for the circuit.

Chevrolet Suburban/GMC Yukon XL, 2000-05 Chevrolet GMC Trucks Silverado, Sierra, 1999-05 Chevrolet Venture 2000
Turn the ignition key to the RUN position. Fully push and release the accelerator pedal 3 times within 5 seconds. If the CHANGE OIL SOON light flashes 2 times, the system is reset. However if the light comes on and stays on for 5 seconds, the system did not reset. Repeat the procedure if the system does not reset.

Good luck and please rate. Keep me posted, and thank you for using fixya.

Recentley when I start my 2004 chevy silverado truck, it knocks and blows smoke for a few moments, then it runs fine. I have had the vehicle for 6 months.


It sounds like you have a seal problem and that is when you stop over night and the oil up top runs down past the valve seals and when you start it has adrop of oil going onto the piston,s and it burns that oil and also makes the compression a lot higher than it should be ,,causing the knocking and as soon as the oil burns up the noise stops.
