Find the right TD5 oil leak parts
Start with the area of the engine where fresh oil first appears. Oil can spread across the engine, run down the block or collect around the bellhousing, making the highest clean and visibly wet point more useful than the lowest oily area.
| Leak area | Parts in this section | Check before ordering |
|---|---|---|
| Rocker cover and top of engine | Early and late rocker cover gaskets, sealing grommets and rocker cover bolt kits | Early 10P/11P or later 15P/16P engine, gasket brand and whether the grommets or bolts are also being replaced |
| Front camshaft seal | Front camshaft oil seal and upgraded Viton camshaft seal-carrier O-ring | Confirm which sealing point is leaking; the oil seal and carrier O-ring are separate parts |
| Rear camshaft seal | Rear camshaft oil seal | Confirm the leak is from the camshaft sealing point rather than oil travelling down from higher on the engine |
| Front crankshaft seal | Front crankshaft oil seal | Seal position and original part number |
| Rear crankshaft seal | Genuine Land Rover, Corteco, Victor Reinz and selected replacement rear crankshaft seals | Brand or quality level and confirmation that the rear crankshaft seal is the source of the leak |
| Oil filter and cooler housing | Oil filter housing gasket and oil rotor filter housing or oil cooler O-ring | Exact housing joint and original gasket or O-ring reference |
| Engine sump | TD5 sump gaskets in selected replacement and Victor Reinz versions | Gasket brand and whether the leak is from the sump joint rather than oil running down from above |
