Knock knock who's there? It's me, #4 and #6. Another ram 6.4 failure. No fixing this one. Therefore we had to install a new engine from Mopar. Not sure about the service history which im sure played a huge role, but keeping up on the oil changes at 5000 miles with the correct 0w40syn oil would have been much cheaper.
The intake was even melted and some yahoo tried using an excessive amount of silicone to seal it.

Some recent jobs completed this past week include a typical 6.4 lifter failure on a RAM. The customer was fortunate to have brought it to our attention promptly after the tapiddy tap tap noise started, which saved the camshaft from damage. It recieved oem Mopar lifters and gaskets.

Moments like this are why we love what we do. 💚

Receiving a handwritten thank-you note from a customer truly means the world to us. Knowing that taking the time to listen, care, and help fix an ongoing issue made a real difference is a reminder that it’s always about more than just cars.

We’re incredibly grateful for the trust our customers place in us and for the opportunity to go the extra mile. Thank you for the kind words and appreciation—it truly made our day! 🙂🎉

Its not always the problematic lifters failing in the 6.4 Ram. Having the common tapity tap tap noise with mis fire it sure sounded like a lifter. After removing the cylinder head we found the valve was not seating correctly and it was hitting the piston.
Installed new cylinder head with lifters
