Ok, How long has it been making the noise? When first started do you check the Oil Level?
When you took it to the mechanic did he check the Oil Pressure?
If it is the lifters I would highly recommend replacing all of them not just the ones that are bad. However, since it is only 6 years old there is another problem somewhere to cause them to fail prematurely.
There are other possibilities to the noise and won't know for sure till start taring down.
What you should do is ask what the cost would be for your mechanic to pull valve covers and look at cams, valve springs and all for ware.
