Hi, I have a 2000 Impala with a 3.8 V6 that has been well maintained. It has about 65000 miles on it. A few months ago I started it up and noticed a slight tapping coming from under the hood. It only lasted a few minutes and went away. I check the oil and it is good. Since then, the tapping has returned a couple of times, every time it only last a few minutes. If you rev the engine, the sound also speeds up. Other than that this car runs great. No warning lights or changes in the gauges. Starts fine, has plenty of power. Any ideas? Thanks in advance.
have the same problem?
