So I had the truck in for service yesterday, and the tech reported seepage at the bedplate. The standard Ford response is that when detected, the leak should be fixed via bedplate gasket replacement. Cost, just short of $4000.
I've hit all the diesel forums for info. This is apparently a not uncommon problem in diesels, including the Ford (International) 6.0 and 6.4 engines ( I have the 6.4). Totally confusing on the advice on the forums. It's almost 50/50 on "get it fixed" versus "let it go as long as you can". I did notice many of the "get it fixed" recommendations were to guys still under warranty.
Though the dealership (at my dad's place, it's the first time I've been to it) put dire warnings (including exclamation points!) on my invoice about how I'm assuming responsibility for a repair I declined, I did manage to talk to the tech at the shop. He said that while he recommends getting it done, I could potentially go another 50K miles before I REALLY need to get it done. Right now as per his inspection, it is barely a seepage, and I haven't seen any oil spots on the ground where I park.
I crawled under to look around, and I saw where things were wet (damp, really). I cleaned everything off and am gonna start monitoring to see how long it takes the seepage to build back up. I also specifically asked the tech if this could be catastrophic, like in all the oil suddenly blowing out in two seconds on the freeway, and he said "no". While not catastrophic, he said it will only get worse, but no way to tell if it will be sooner, or later.
So long story longer, I'm conflicted on if I should eat the costs now, or wait till I'm finding oil under the truck every day. I'm leaning toward waiting, given how minor the leak is at this point. On the other hand, once I pony up for the repair, it means I'm keeping the truck a good while longer (I've been thinking of downsizing to the new F150 or even a Tacoma), so if I'm gonna do it anyway, why wait? On the third hand, I hate the thought of doing it at all, because with all the work they have to do with pulling off the cab, pulling the engine, putting it on a stand so they can turn it upside down, then reversing all that, I can't help but think of all the little things that might not be put back exactly right during the procedure, and end up causing me nickel and dime problems down the road.
On the fourth hand, diesels are diesels, and as Captain Ron would say, diesels love oil like a sailor loves rum. Thoughts?
