2006 Dodge Magnum 2.5 HO

Internet advice says change the offending lifters. Tons of dodge owners have the "ticK"!

If you have had no success with flushing and oil changes, it will be a faulty valve with in the lifter, it is good practice to replace all the lifters as a set, it will cost a bit more, but when done you will not have to worry about doing the work again if another starts to fail later on.

Be also advised when lifter problem occurs the camshaft has to be miked to check the lobes/ condition, normally both are replaced at the same time-they're partners in crime just like the distributor cap and rotor-

This is freaky! Chiltons online does not show 2.5 but only 2.7 motor for this car? This is public access chiltons though, what can I say?
Anyway, this job is EASY! Remove valve cover where tick is apparent, loosen cam bearing caps(ends first, work your way to middle)over offending lifter when located, move rocker arm and remove lifter. Since the job is fairly easy I see no reason to replace them all? But maybe that's since i'm a do it yourselfer? You could replace all lifters on that cam and save the used good ones for any future problem? I would have no problem usuing an outside mechanic as you call them for this job. And as a final note, the problem may not turn out to be the lifter itself? No way to tell until you inspect everything.

Still noisy -could be a camshaft problem, did they replaced the camshaft
