This Pentastar 3.6 liter engine ran an incredible 626,000 miles before giving out. It's amazing to see how well the engine held up. (Note- The oil was changed every 8,000 miles).
With well over half a million miles on it most all engines would be due for complete overhaul or replacement especially newer engines, id say its a good engine.
Was told by my head mechanic at my dealer that the pentastar is the most dependable motor they make, it is made to go for a lot of miles.
The thumbnail of that engine on the video is the best view of the strange exhaust port layout I have yet seen. That Exhaust port layout just BEGS for a turbocharger. A turbocharger cares little if it is mounted on an old-school cast iron exhaust manifold or a long-tube header, from a performance standpoint. Cylinders just scavenge better and display more consistency on a long-tube header, with lower EGT's, but if you throw enough fuel at it, you get the same performance from a turbo right on a manifold. The 1000°C EGT's might not be the aluminum internal dividers' favorite thing, however. It looks like a modern engine, in general, I am just prejudiced against those exhaust ports, mainly for thermal reasons and consistency reasons. The block casting looks shrink-wrapped around necessary internal spaces for coolant and oil, as well as bolt bosses, for modern minimal weight. How much does that engine weigh? Half a Hemi?
