Howdy, y'all. A year into owning my 2012 1500, 5.7 Hemi and the engine crapped out.
I'm suspecting it's cam and lifter failure.
Cylinder 3 misfire after replacing all spark plugs. Technician found gunk (oil and carbon I suspect) built up on one side of cylinder 3 and a 120 psi pressure.
He got a borescope in there and saw that the valve doesn't move whatsoever when he turns the motor over by hand.
Metal debris found as well.
All other cylinders clean and up at 210 psi.
His suggestion is engine replacement rather than repairing this one.
I'd have liked to replace the cam and lifter with an MDS delete system, replace the fuel pump, and get some good steel shortys.
I'm being told by the technician and my step father (30+ year mechanic) it's better to just replace the whole thing with a new one under warranty.
I'm sticking with the truck with where I'm at on the note.
Any thoughts on the risks to repairing this engine rather than replacing?
Any recommendations on best sources for a rebuilt or new engine?
Thank!
