The car manufacturer worked with West Midlands Police to investigate the theft at its Solihull plant which took place between 31 January and 1 February.
The stolen engines were found during raids in Sutton Coldfield and Warwickshire, following their theft on 31st January, which saw a tractor unit enter the Land Rover site in Solihull and hitch up to trailers full of the engines. The lorry entered the site a second time, again hooking up to trailers where the engines were stored.
Following investigations, officers raided locations in Kingsbury Road, Minworth, and Bermuda Industrial Park, in Nuneaton resulting in four men aged 29, 40, 47 and 56 being arrested on suspicion of conspiracy to steal.
“This has been a fast-paced inquiry and after searching two locations today we have seized what we believe are the stolen engines,” said Solihull Investigation Team Detective Inspector, Darren Lee.
“This is a significant find and we continue to investigate the theft.”
All the engines have been recovered, with the four men bailed until the 22nd of March pending further enquiries.
Officers are now appealing to anyone who witnessed the theft or saw anything suspicious at the Minworth or Nuneaton sites in the last few weeks to come forward.
