5.7 Hemi dealer says needs cam and rockers on driver

They have roller rockers ,likely seized up and wiped out the cam ,more common than you think.

They have roller "lifters", not rockers.

The cost likely would come from labor involved in taking everything apart to do the work. Still, my son works at a dodge dealership and that's something he has done in a day. The factory lifters are 4 or 5 hundred bucks for all of them and the cam aint 5k. Neither are the rockers....

Something isn't right
