Block crack – weldable or scrap?
Dropped sump on my high-mileage Transit 2.2 TDCi and found a hairline crack in the block between cylinders 2-3 (water jacket side). No overheating history, but coolant in oil now. Can these be welded or sleeved, or is the block toast?

Small cracks in cast iron blocks can sometimes be repaired with specialist welding (Ni-rod or similar) or stitching if not structural, but on commercial vans with high stress, it's risky- crack can propagate under load. Many go for used/reconditioned blocks. I had a similar find on a Transit- opted for a low-mile donor block. Found a compatible short block assembly and individual crankshaft parts at https://elartcom.eu/categories/engine-block-and-crankshaft-141 - they list block-related components and some reman cranks for Ford Transit engines. Transferred my head/pans over- saved vs full new engine. If welding, get a pro engine shop opinion first. Their category is useful for sourcing spares if rebuilding or swapping.
