What is the 1986-1990 Land Rover Defender 2.5 Turbo Diesel (19J) block cracks and breather-induced engine runaway?
When Land Rover turbocharged the well-liked 2.5 naturally-aspirated diesel to create the 19J, they bolted the turbo on without adequately strengthening the bottom end. Owners and rebuilders report internal cracks developing in the cylinder block and cracked/holed pistons appearin… Repairs typically run $400-$4,000. Severity: high.
What is the 1983-1990 Land Rover Defender Chassis corrosion — rear crossmember and outriggers rot out?
The early 90/110 left the factory with a painted (not galvanised) steel ladder chassis that begins corroding almost immediately. The rear crossmember sits directly in the spray off the rear wheels and is the first to go; the body-mount outriggers and the chassis rails around the… Repairs typically run $250-$4,500. Severity: high.
What is the 1983-1990 Land Rover Defender Steel bulkhead rot at footwells, top corners and A-post feet?

What is the 1983-1990 Land Rover Defender LT77 / LT85 gearbox weak fifth gear and rear bearing failure?
Early 90/110s use the LT77 5-speed (four-cylinder diesels, 1983-89) or the LT85 (V8, from 1984), and both share a weakness around fifth gear. On the LT77 the overdrive 5th is effectively an add-on hung off the end of the mainshaft/layshaft and is poorly supported; the rear mainsh… Repairs typically run $400-$1,500. Severity: medium.
