Re: 2012 Sienna - Engine Block Cracked!!
I'm not sure what's up with this tread, but I'm going to delete my initial entry and repost......
Who took the picture, and what is it telling us? I think the photographer is standing behind the front wheels looking forward towards the front bumper. The transmission lower bell housing is on the left, oil pan on the right.
Center stage is the exhaust pipe from the front bank, and we are looking at the exhaust under-engine bracket. I think that stamped steel bracket is bolted to the pan. Both bracket bolts appear to be place, but it looks like a bit of the oil pan casting between them is torn out and resting on the bracket? It's hard to tell for sure. I think I see a crack line extending over to the left bolt.
At the bottom of the engine block is a bolt-on lower skirt (upper oil pan), and below that the real oil pan. I'd have to crawl under to verify exactly where this bracket attaches, but it looks to me to be physical damage of some kind and a chuck of the casting is broken free? Did you suffer an impact of any kind? Did the pipe get hit and the jolt fracture the casting? This doesn't look like the type of damage that's typically caused by an internal issue (running out of oil or coolant). But I'm just guessing....
If you are still sure this is an internal issues, ask for a review by the District Manager.
If there's an external cause, you might be able to get some help from your insurance company.
