Definitely. If you're lucky then only the valves are damaged and that can be repaired by removing and overhauling the cylinder head. The water pump will and cambelt tensioners will also need to be replaced as they're relatively cheap and if they fail after repair the cambelt must be removed again. If you're unlucky then the piston crowns have been damaged or even the cylinder liners and this requires a complete engine rebuild. If only the valves are affected then the engine can usually be successfully repaired at a reasonable cost, but it's vital to get the head checked for cracks and flatness before reassembly as the stress on the combustion chambers and valve guides caused by a belt failure can warp or crack the head.
If time is money for you, then it may be cheaper to fit a good used engine. Note that there are no cheap "reconditioned" engines regardless of whatever worthless guarantees are offered. If you go for a reconditioned unit then if you're in the UK make sure that the engine supplier is a member of the Federation of Engine Remanufacturers
(FER). Don't just rely on the logo on signs and stationery, actively check with the FER as some dodgy outfits have no qualms about claiming to ber members when they're not.
A good used engine will cost around £160 or so, make sure that you can hear the engine running before it's removed from the scrapped donor vehicle. It's cheap, but a risky choice and you'll need to add the cost of an immediate precautionary cambelt and water pump change.
A "reconditioned" engine means nothing. It might only have been degreased, repainted and had an oil and filter change. Recon is often a con.
A remanufactured engine will have been cleaned and then carefully tested before being largely or even completely dismantled. It's then rebuilt to precise tolerances using new or remanufactured parts. Expect to pay around half to two thirds of the cost of a brand new engine; they're not cheap but they are far cheaper than a new engine and will be supplied with a really worthwhile time/distance warranty.
I hope that you get your van fixed soon and that the damage isn't too serious. If my reply has helped then please return the favour by rating my answer.
