Ford V-10 6.8L Seized Lost Oil Pressure
Hello,
I am making a post to share my experience in case any one is searching and looking for advice.
I have a 2015 Class C RV on a Ford E450 chassis with the V10 Triton 6.8L engine. The vehicle only has 21,000 original miles on it and we have done about 3 years of trips on it no problem. I did an oil change only 1,000 miles ago at the most & the oil level looked fine, used Ford Motorcraft oil filter as well. We bought it with 17,000 miles and it ran just fine - no concerns, well maintained.
I was about 100 miles into our next trip and gauges looked fine and all that. I was driving up slight grade at 5,000 RPM and next thing I know, the gauges catch my attention. Oil pressure had dropped to 0, the oil light was on, and it started to rev down to a complete stop within 60 seconds. Nothing sounded strange, just the engine revving down through the gears. The battery, fuel, coolant gauges were reading normal, but oil pressure was 0. I go to start it again and the starter was engaging but not turning over. We got towed up a little bit to a safer spot to troubleshoot more. The next day, I got a 18" breaker bar and an 18mm socket on the crankshaft pulley to try to turn it over by hand. It was stuck. I let up tension on the belt and all the accessory pulleys spun freely, so it's not a locked up accessory.
Anyways, justing posting here for ideas and anyone else who does a frantic google search like I did the past 48 hours to dig as much info as possible. From what I read from other posts, it looks like if it is seized, an engine swap is needed. I was going to drain the oil and check for metal / shavings. Before I start pulling it, are there things I can do in the disassembly process to check out? One major problem is that I can't turn it over to separate the flexplate from the torque converter. What would I do from there if I cant end up separating it? My engine hoist is rated for 2 tons.
