Hi, Just bought my first Landrcuiser 105 series petrol with LPG. I'm looking to buy a spare engine and do a slow time rebuild, nothing wrong with the current one except the kms are getting on and this truck is a keeper so I want to make it reliable for long trips. I'll be overhauling a few bits along the way. Does anyone have any good links to online manuals for the engine rebuild and the vehicle. I've searched but came up with a lot of dead links. Cheers Karl
