    This is my first post and I wish it was on another topic. I have a 2015 Challenger Hellcat that the engine had to be replaced at 1361 miles. Cause was I/C (supercharger) coolent fluid leaking into the first cylinder (piston 1). This showed up as a "sweet smelling smoke" at the beginning that went away, came back and then seized the engine. My dealer was awesome, got a new engine off the assembly line and had it stamped with my correct VIN, so everything still matches. Just got her back two days ago. So my question is how should I break it in? I've gone through the owner's manual break-in once, which I assume the speed, braking, etc, criteria are also for transmission, brakes, etc. break-in. All of that is broken in, so I am wondering if I should focus more on RPMs and managing that during some period (?) to break the new engine in. The dealer played it safe and said, first Hellcat engine we've replaced, so you should probably just follow the owner's manual recommendations again. Thoughts and ideas appreciated, and happy to join the forum.

    Do what the dealer says. It's only 500 miles...

    Break in recommendations are just that..recommendations. That engine has already been run in for 42 minutes on a dyno. Don't get caught up in the numbers. Just take it easy and don't beat on it for the first 500. Common sense prevails.

    Welcome to the forum. Wow! Crazy great story. I'm Glad it turned out good for you. It sounds like you have a great dealer. Nice they were able to stamp your original VIN number on your new engine. Do you know the build date of your car?

    This is correct. The 500 mile break-in is mainly for the drivetrain. That engine was tested for 42 minutes throughout the RPM's already. Just take it easy and honestly can already begin having fun at this point

    Go to the nearest interstate or freeway. Run it up to 145-150 mph then slow down to 60-70 mph. Repeat this 3 times and then your completely broke in.

    I'd play it safe...doesn't hurt anything. Remember to check the oil after each 100 miles or so to be on the safe side, for the first 1500-2k miles.

    The dealer is Clovis Chrysler-Dodge-Jeep-Ram in Clovis, CA. In spite of the engine issue, they have been great!

    Broke it in as close to the owner's manual recommendations as possible. Honestly, kind of babied it bit to make sure. Going to give it the 500 miles as everyone is suggesting before going all out, but I will relax on the babying part.
