    He’s right, some brand new 2020 350s going early. At least 3-4 under 1000 miles. Looks to be a different issue than what plagued the (17-early 18) 350 motors with crazy oil use

    Link to those?

    The 2020 cars share a block with the gt500 which is a closed deck design and stout as hell.

    I’d like to read about what’s happening to the 2020 motors.

    I've been researching the last several months on the 350's listed for sale online. It seems most are the 17's having alot of issues and 18's as well.

    If I were to buy a used one, I would get one with a new Engine/Drivetrain replacement that is a buyback from Ford. They are guaranteed for 12 months and most likely will have the 20' long block. Of course the 1 downside is diminished value but you most likely are already buying it at a very good price. I've seen some great deals offered on these cars and there are 3-4 Ford Dealerships I've found across the Country that specialize in these Buyback/lemon 350s.

    I've watched the progression of issues with the GT350 since they came out - I have an early 04/16 build and it's been great.

    If you haven't seen this (GT350 Engine Failure: By The Numbers - Overrun) yet, it's got a lot of data that's boiled down from social media and other sources. Tricky bit was de-duplicating the reports - "blown up Vooodoo" is high powered click bait, so a lot of people re-reported the same failed engine to drive revenue, likes and subscriptions.

    Basically the 2016's had a few failures for random reasons, but on the whole they've got a decent reliability record. Starting 2017 and into 2018 they had two failure modes - high oil consumption or "random" spun bearings, broken pistons and other weird stuff. OPG's got a lot of the blame, but there's no solid evidence they're actually a problem. As an example, one poster on another forum decided to swap in new OPG's, and when he took his old pump out, it was damaged. He tore the engine down and it turned out that a valve spring had broken and a bit of super hard spring steel had gone through the pump. His engine didn't fail, but had it, it would have been another "we knew these pumps weren't strong enough" cases. 2019's have shown a few failures, and two of them have been with intake valve heads that detached from the stem and smashed up the head and the piston as the engine ran. At this point, the 2019's seem to be more stable than the 2017's and 2018's, and there just isn't enough data on the 2020's yet.

    In terms of reliability with FI, the one thing that needs careful attention is the crank damper. The Voodoo damper is special because of the harmonics, and a regular Coyote damper could leave you with a damaged oil pump or even a broken crank.

    Your research is spot on. I’ve never seen anything like that, and no way I’d buy a 17-early 18. I would take my chances on a 15-16 or late 18+.

    The guy that wrote that overrun article about the “hysteria” was on his 3rd engine before he lemon’d that POS...3!!... Pretty ironic, don’t ya think
