This morning YouTube served up a 25 minute video of a Series III Land Rover (same as mine) getting fitted with a newer 300 Tdi engine.
My Land Rover had to undergo the same procedure back in 2018 as part of the restoration. I purchased a rebuilt 300 Tdi from Zombie Motors out in Oregon. Photos here, here, here and here. Not cheap. But less expensive than having the engine shoe-horned into my Rover. I feel better about what I paid after watching this video. And in the five years I’ve been driving the Land Rover, it has never failed to start on the first crank. Not once.
