Common Engine Problems: A Deep Dive

Oil Leaks and Consumption

  • Solution: Our remanufactured engines come with improved gaskets and seals, tackling notorious oil leaks and consumption problems. This helps you maintain engine health and reduce the need for frequent top-ups.

Lack of Power and Performance

  • Solution: Rover Parts Depo's remanufactured engines are designed for enhanced power and performance. With precision engineering and meticulous attention to detail, our engines reinvigorate your driving experience.

Aluminum Blocks & Steel Piston Sleeve Age and Wear

  • Factory design on these Land Rover engines featured an all-aluminum block casting fitted with steel piston sleeves. Repeated heat expansion of these two separate metals (aluminum and steel) often lead to leaking piston sleeve cylinders. Most often, pressure leaks occurred where compression gasses escaped around the edges of the sleeves and into the engine block. The prolonged effect of this gas leakage often lead to "slipped sleeves", where the piston sleeves loosen and actually drop/move within the block housing. The result is a failed engine that often leaks coolant into the block.
  • Solution: Our remanufactured 4.0 / 4.6 / 3.9-liter engines correct this sleeve pressure seal problem by machining out the defective sleeves and replacing them with all new, top hat sleeves that feature a specially-designed top flange that secures/seals the sleeves with the engine heads, preventing gasses from escaping around the sleeve tops and ensuring the sleeves will not loosen or drop over time. Each original engine block is parallel-decked to the main bearing saddle, which provides even compression across the entire block. These process modifications protect against compression gas leaks while improving the performance of the Land Rover short block or long block engine.
