Unhappy Repair after timing chain jump

The timing chain jumped on my 2013 X3 at 130,000 miles (beyond the extended warranty). The dealership says it needs a $14500 engine replacement. My local import car mechanic says a $4000 repair to all the timing system components might do it, unless they find more damage after starting the repair, which would be an engine replacement. They suggested I have a 50/50 chance at avoiding the engine replacement. Iím looking to calibrate on the odds here. Anyone have experience (successes or failures) repairing an engine after a timing chain slip? I pulled over a hundred feet after getting the drivetrain malfunction error and the engine shutting down.

Hi,
Have you looked for a S/hand engine from a wrecker / dismantler / salvage yard? (and ask your import mechanic to fit it for you).
In my view that is a better alternative than repairing your engine, as it would limit the risk of paying for labor just to find out that it is scrap.

Not sure which engine is in yours. Petrol?
I am currently playing with a Ford / LandRover TDV6 2.7 engine that had snapped timing belt. It doesn't have a fancy 'Valvetronic' system, and only has some simple problems to get it going again. But when the pistons hits the valves something have to give. In my engine that appears to be only some broken valve lifter arms and some stretched bolts on the cam bearing caps, and one bent camshaft. On other engines it could be bent valves, damaged valve seats, damaged pistons, damaged connecting rods. You don't really know until it is dismantled.
Cheers,
