Question about 2003 Chevrolet Silverado 1500
A single knock, sounding like a rod bearing knock, when the engine is started. This occurred in all climates/seasons. at the beginning we only the first 5 minutes, but in the last 4 days that knock is permanent.
I took the truck to the dealer when it was under waranty, but they said was normal. Now I gor 100,000 miles and the sound is permanent.
I hate this truck since the beginning , I hope not buy a GM anymore.
This is normal with the 2000 to 2003 silverado 1500 after about 70,000 miles. It is not a worry. after truck warms and the oil has lubricated the engine, the tic noise should stop.

I am not going to tell you that I can solve this but there are a couple of things you should try before you get an overhaul. If you have had this problem as long as you have had the truck like for several thousand miles, I think it is a lifter and not a rod bearing. A knocking rod bearing would have crashed big time after a few thousand miles. First drain your oil and replace it with naptha and run it for a few minutes and then drain it out. and replace it with a premium oil (not synthetic) one quart short of full. Then in place of the last quart add a quart of Lucas oil treatment. The objective is to break loose the sticking lifter. If this does not work try it again. You can use the same naptha and the same new oil with the Lucas treatment to go back in. This is a common problem with the silverado.
