[QUOTE="unashamed7, post: 2098175, member: 73233"] Mostly posting this to vent, but also for any advice. Ok here’s my story: Relatively new to me 2017 Gen2 Raptor I bought last May (8 months ago) has let me down. I took a gamble and bought a higher mileage truck (169k). The previous owner was honest with what was done, no mods besides fitting 37s onto the truck. He claimed he didn’t off-road it and the high mileage was mainly his wife using it to take the kids to school far away, and his daughter drove it a lot in high school. 7 yrs, 169k is about 24k a year. He did say he got a tune for it earlier on but put it back to stock for his wife and kids (no way to verify). The truck was really clean and well kept overall so I was hoping for the best. He just had some work down to replace the Cam phasers at 100k, transmission work and new spark plugs at 165k. Purchased for 29k (plus DMV tax). After I bought the truck I babied it for a while, getting used to it. Then I started to push it a little bit, but never extensively (accelerations into the freeway, etc). Took a camping once which really was just some slow back roads in the mountains. I took it to a little off-road dirt/sand lot about two weeks ago and had a bit of fun. Put it in baja mode, did some donuts, did a couple laps around for a short time, maybe 5-10 min. You know, what the truck was made for. I drove down the street and parked it for 20 minutes and everything seemed fine. I go to get back in to drive home and heard some strange clunking noises I thought was just the transfer case not fully disengaging. I pulled over and listen to the engine which sounded OK (but I’m no mechanic) and put it in four wheel and back to two wheel. I got back on the highway and the sound went away so I assumed everything was fine. It’s not my primary vehicle and so I didn’t drive it for about one week but when I went to start it up, the check engine light was on and misfiring codes were being thrown (P0316, P0306). I tried swapping some coils, no luck. I decided it was best to bring it into a professional shop to take a look this week. They’ve had the truck for a two days and when I called them last night, they said that they didn’t have a full report yet but the comp compression test failed for cylinder six at 20 psi, and cylinder six looks like it has pitting on it. Because of the higher mileage of the engine, they recommend just fully replacing the engine with a replacement crate motor from Ford. The truck now has 172k and I got an oil change and some other fluid replacements done about 1k miles ago and overall the shop gave it a clean bill of health. I was really hoping it would be a coil or a plug, but it was literally worst case scenario. Don’t have the quote yet, but it’s not going to be cheap, [B]what would you guys do? Is the truck even worth keeping after replacing the motor?[/B] Feeling pretty terrible right now. I will update back here with the quote when I receive it. [/QUOTE]
