I've got a '19 1500 classic 5.7 Hemi, it's been in the dealership for a few weeks with a no-start problem they found a broken timing chain and replaced it and it's still not firing up so I guess the pistons kissed the valves when the chain blew. so far they've done a compression test, I've got several cylinders with what they've said is "inadequate compression", found a few decent-looking parts engines near me and I'm thinking to save myself 6k in labour and parts i'll just replace the heads/valves myself.
TL;DR
- motors messed need to know if parts off a 2012 will fit a 2019 (specifically heads and valves but I plan on keeping the motor for parts afterward)
- need to know roughly how much is involved in replacing heads or valves (id rather do the valves themselves and save the rest for parts in case this happens again, and yes I will be getting an entire seal and gasket kit)
- also what is considered adequate cylinder compression? is there a range I can base off?
p.s I'm familiar with cars, I'm a decent mechanic been working on cars my whole life so I'm in for a challenge just wanna be prepared and don't wanna get in over my head.
