The creator of the video calls this noise "normal". I'm not sure if I agree with that, but it is very common.

The noise in the video is very similar.The tick is present all the time>How can the rpoblem be curred.
If it is indeed piston slap, there are a couple of options that you could explore. One is replacing the engine. The second involved a lot of tear-down and machine work. However, I would only consider these options if you absolutely cannot live with the noise. Have a reputable mechanic check the car out - including a compression test - if he believes that the car is mechanically reliable, and you can live with the noise, try not to worry about it. There are many 3.1L engines that have been experiencing the same issue.
I have another set of lifters that I getting put in.Is there anything that can be done while at this step of the teardown to see what the problem.If the second set of new lifters does not cure the problem,Can the tick cause any future problem
If it is indeed piston slap, the lifters will not affect the noise. Piston slap will cause premature engine wear - specifically on both the cylinder bores and the pistons. This will eventually lead to oil consumption. With excessive piston ring to cylinder bore clearance, engine oil will enter the combustion chamber and be burned. Engine longetivity will be adversely affected.
Tick has been there for about a year or more now.It still does not burn any oil and other than the tick runs great.If it was piston slap do you think that after a year or so of driving i would have noticed oil consumption or other problems.
