5.7 Hemi dealer says needs cam and rockers on driver

Chrysler put a whole new engine in my ram when that happened...It was a siezed lifter, that wiped the cam. Ask them to drop the pan, and do not clean it. Tell them you want to inspect it when they do. There will be a lot of metal shavings...Be sure to take pics of the metal that has circulated throughout the whole oiling system... Then do not settle for anything less that a new engine.. It is likely they have not even dropped the pan yet.
