Question about Cars & Trucks
Really??? Lifters are about the only thing that can make noise in this V6 valve train. A broken valve spring can cause noise but that would turn on the check engine light and the engine would misfire on that cylinder.

You could have carbon build up on the back of the valves that is bad enough that it could cause a noise like pre-ignition and if its bad enough it could cause a problem.it usually will cause the engine to sometimes run bad or have hard starting when the engine is cold as the carbon soaks up the gas until it can`t assorb any more.this can be possibly repaired by having a fuel system service that runs a chemical through the motor by use of a machine..it could also be bad valve guides or valve springs allowing the valve to not move up and down straight but on an angle.kind of like holding a pencil in your hand with some resitance and moving it up and down and then lossening your grip on the pencil and doing the same thing it won`t try to travel straight.

You could try running a flush chemical in the engine oil just prior to changing the oil, and then using synthetic oil. This may free up the little tiny valve in the lifters and reduce the noise. At the very least, it will help prolong their life. It is a very big expensive job to change these because they are generally replaced as a set and they are not cheap, but replacement is often the only true fix.
