Cam phaser to camshaft correlation lost

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Great question, and this is definitely a tricky situation! On your 2010 Chrysler Sebring if the camshaft jumped timing during the chain removal process the cam timing will need to be properly realigned before the engine will run correctly. In many cases this can be corrected by carefully repositioning the camshaft to the correct timing position using the appropriate timing marks and locking tools, without necessarily replacing the phasers themselves. However whether the phasers need replacement really depends on whether they were damaged during the timing jump or if they were already worn prior to the repair. That said, getting the cam timing correct on this engine requires very specific timing tools and procedures, and an error in the reassembly can cause serious engine damage including bent valves if the engine is cranked with the timing off. This is really a job that needs to be handled by a qualified shop with the proper timing tools and experience with this engine family. I'd strongly recommend not attempting to start the engine until the timing has been properly verified.
