4.7 blew up, now I have some questions.
Ok, I am registered to this forum all for the dodge ram stuff since i'm a ram guy but it just happens my mom has a dodge durango with a 4.7 in it. The ac quit working and my mom brought it in to get checked out and they said the electric fan on the ac was out and she needed a new manifold gasket. My mom ok'd the repairs so they did it. My dad picked the car up and not even 15 miles after picking it up the blew completely seized and the shop is trying to say there is no way it is their fault. I am here to ask you guys if there is anyway this could be their fault or if they could have done something wrong that made this happen? I just see it as a rather odd coincidence.
Anyone who responds to help me with this is my hero, thank you for any help what so ever.

maybe they left something out when reassembling... or left something in.... I would have someone else check it out and document the cause of it seising.

I agree. Maybe something dropped down into the oil return and plugged up the pump. Get a second opinion. If anything you could take them to court and get your money back and a new motor. Get a sample of your oil and have it tested.

Well of course there in NO WAY replacing the blower motor would cause the engine to sieze - so we can forget that....
Replacing the intake manifold gasket could cause a problem, but hardly anything to cause an engine to sieze.
We have been fortunate enough to not have made any big mistakes like that, but we have made some mistakes - and made every effort to make it right. And we have to fix lots of mistakes made when someone takes it to some "backyard mechanic" that doesn't know as much as he tells people. So, I know things can get screwed up in a shop, but I still won't be quick to point fingers.
Even if a bolt got dropped into the engine valley (or worse, the intake port) when the manifold was off, all that would do is destroy one piston...I would have a hard time believing they caused the engine to sieze.
Take it back to the original shop and look at the engine after they get the heads off. Ask them what they think caused it to sieze.
If it was thier fault, you will have a lot better luck getting them to cover it (or at least part of it) if they do the work.
