I'm working on a F300 with a manufacture date of 03/2013 and only 254 hours (I thought the thrust bearing "issue" was fixed after 01/2013?). Was having a good time w the kids, and suddenly the oil pressure dropped and the engine stalled. Repeated attempts but could not restart. I checked the oil and it was EMPTY. We got towed back to the dock. I filled it up with oil and tried to crank and no go. Then I noticed the timing belt was all chewed up and off the pulleys.
So, do I have the dreaded thrust bearing failure? Is this an interference or non-interference engine? I have been doing research but cannot find a clear answer. I believe the 225/250 is non interference and below is interference. But I have seen no reference to the F300 (hopefully the bigger engines are all non-interference?). If it is interference, and I continued to crank it, did it bend the valves & damage the pistons, or is that just already guaranteed once the belt failed?
I tried to pry up on the flywheel, and absolutely zero movement, so I am stumped. Could i just have a bad belt? Why did the oil disappear? I fear the engine is "TOAST", so I am going to attempt a little investigation myself before I hire a pro. I figure I will cut the oil filter open and inspect for signs of heavy metal damage. If I find this, then I guess there is no point in continuing.
What would you do first? I believe it is not as simple as putting a new belt on, there is a specific method and if not followed I could damage the engine if it is already not toast. I have a new filter and oil and ordering a new belt at any moment if its worth trying? Since the warranty expired, I have been using Sierra maintenance items and fluids which I don't believe should be a problem.
Please advise. thank you.
