Never heard of that happening (or being a common failure) on that engine.
Same here for the head gasket but the LIM history is dismal.
Dealer wants to replace the engine for $5,400. I dont think so.
If the engine was run low on coolant( Bad LIM gaskets ) the Alluminum heads will not tollerate it and the head gaskets will fail in short order... If the bottom end is still good I would be tempted to yank the heads and get a head gasket kit that will include everything you need... But the heads will have to be straightened and cut at the machine shop to make sure they are true or the head gaskets will live a short life...
I have seen LIM issues on the 3400 like crazy.... And in turn that would cause a head gasket failure... But we have yet to come across a totally destroyed 3400...
Which brings me back to the question... How is the bottom end? Was it doing any knocking? and would you have the patience to rip into the 3400 parked under the hood of the Van? This can be a Royal PITA...
If you have the Patience for this you can save yourself a lot of money...
