What have you heard concerning the reliability of the 2.3 EB? We have a 2017 Explorer with that engine and 46,000 miles so far. The EXTERNAL water pump developed a leak early on. It was replaced under warranty and has run more than 3 times the mileage with no more leaking. Just before the 3/36,000 mile warranty was about to be up I had the dealer look it over. I was advised that the front timing chain cover was moist at the seam, no leaking though. That was replaced under warranty also. Originally from the factory the timing cover used rtv as a sealer. It looks like for the repair they used a gasket instead of rtv. I understand this leaking occurs occasionally on both the 3.5 & 2.3 EB's. Other than that the 2.3 runs great, lots of power, quiet, and good mpg. I use only plain Mobil 1 5W-30 and run it to 6-7500 mile OCI, well short of the iOLM. Also we use top tier 87 octane fuel, almost all Shell. I'm hoping for a long life from this Explorer. Our 2005 4.6 Explorer with 197,000 miles is still going strong, of course it gets 1/2 the mpg of the 2017
