I haven't raced it in several years, but my 2004 Ram 2500 4wd with a 5.7 Hemi with 299k miles on it was doing fine with no issues, that was until I loaned it to the father in law.

It came home on a roll back and after finally getting time to check it out and it had broken a valve spring on the number 8 cylinder and subsequently dropped a valve.

I now have to decide what to do with it.
