engine ticking and popping through exhaust
my 5.3 started ticking from driver side, can hear it better through wheel well, and under acceleration pops through exhaust. oil pressure is perfect and everything checked out on lap top, all cylinders firing, knock sensors not picking up anything and no codes. Im thinking its a bad lifter on exhaust side. i drained the oil and cut open the filter, no bearing material, but two very tiny pieces of metal that could be be from a lifter. but between the tick and pop in exhaust a lifter is what im thinking. Going to my tuner tomorrow and were pulling the valve covers and taking a look. If it is a lifter, then ill pull both heads and have them worked, change lifters and such. If it turns out i have a much bigger issue, i got a deal on a complete lq4, intake to pan for 450, have it freshened up and throw that in.

Sometimes we over think things looking for the real cause of the problem. And when we do find it we get an argument from a guy that was selling washing machines last week...
Yes the vacuum gauge will tell you so much info. I was really fortunate to learn from some top knotch guys since high school........
