It's been a while since I've had time for this project but here are the updates.
A good used discovery 300tdi was sourced
along with a good used discovery r380
Here are the defender and discovery shifters side by side. Obviously there is a huge difference and the discovery set up won't work in a defender.
To solve this I sourced this adapter from Ashcroft. It allows the defender shifter from the old LT77 to work on the Discovery R380.
The head is pulled from the motor to inspect the pistons and cylinders. The valves get a good clean up to remove caked on carbon and to install new valve seals. Several of the valve seals had risen off the valve guides. Also all the lifters are removed and inspected for wear or flat spots.
This was an early 300tdi and still did not have the updated timing belt, this is a must.
The lower pulley is pulled and replaced with a flanged one.
There is something satisfying about seeing the land rover logo on replacement parts.
The whole assembly is ready to go in. Tons of other parts were replaced as well, new oil cooler lines, fan clutch, thermostat, all hoses, water pump, clutch, rear main seal, glow plugs, the list goes on and on.
