I spoke with a mechanic and he said to make sure and put the right amount and type of oil. My truck takes 8 quarts of 5w30 i believe. He said to check it often when you go on long trips. Its preventive maintenance on a 6000 engine.

that was the first thing I tryed per the mechanics advice. Went to a heavier oil and the noise seemed to quiet down a bit but not for long.

So is this tapping noise a sign of a engine thats about to blow or will the engine last its normal life? In other words, should I get rid of this thing before she blows?
