Used Volkswagen LT Sump

The Volkswagen LT ran across two distinct generations: the LT1 (Mk1) from 1975 to 1996 and the LT2 (Mk2) from 1996 to 2006, and sumps are not considered interchangeable across that boundary due to significant engine and structural differences between the two. Within each generation, fitment is driven primarily by the engine code, so a same-code engine from, say, a 1998 LT2 and a 2003 LT2 is far more likely to share a sump than two different engine codes from the same year. Always confirm the crossing of any generational boundary with the breaker against your exact registration before buying.

The engine code matters far more than the year for a mechanical part like a sump, because Volkswagen fitted several different diesel and petrol engines to the LT across its production run, each with its own sump profile, oil pickup position, and mounting points. Two LTs from the same model year could have completely different sumps if they carry different engine codes. Your engine code is stamped on the engine block and is also recorded on your V5C, so supply it to the breaker rather than relying on the year alone.

No — diesel and petrol engines in the LT are entirely different units with different sump designs, so the two are not interchangeable. Always specify your fuel type alongside your engine code when requesting a quote from a breaker, as this immediately rules out a large portion of unsuitable parts. If you are uncertain of your fuel type, your V5C or a VIN check will confirm it.

The gearbox type does not directly affect the engine sump itself, but it can be a useful cross-reference detail when speaking to a breaker, as certain engine and gearbox combinations were more common in particular LT variants. The sump is an engine component and its fitment follows the engine code first, then fuel type. That said, mention your gearbox type to the breaker as supporting information to help them confirm they have pulled the part from a closely matching donor vehicle.

The LT 28, LT 35, and LT 46 are payload and gross-vehicle-weight designations rather than separate model lines, and they do not in themselves determine which sump you need. Fitment is governed by the engine code fitted to your specific vehicle, which can be the same unit across different weight variants. Give the breaker your engine code and fuel type, and the 35 or 46 badge on the side of the van becomes largely irrelevant to sump selection.

The 1996 model year marks the boundary between the LT1 and the LT2, which brought revised engines and updated underpinning, so crossing that boundary with a sump is not straightforward. Even if an engine code looks similar on paper, ancillary and mounting details may have changed during that transition. Name the boundary to your breaker and ask them to confirm compatibility against your specific registration before purchasing.
