Thanks.
I'm picking up a RRS this week for my daily driver, so my Disco won't get as much use... Mostly offroad use.

Caymandrew, why did you replace the rocker arms? Were there any indications they were worn or was it just to cover all your bases while you were in there.

Inspired by your experience, I'm thinking of swapping cams while I have the heads off in the spring.

Very cool thread, but the video is set to private and I can't watch it. I don't know how this one slipped by me, but I'm sold on this rebuild.

A few questions:
1)You do all of this with the heads still bolted on correct?

2)how hard were the main and rod bearings to replace?

3) I to am thinking of doing this very soon, but I have been thinking about using this sport Cam instead of the stock one. Turner Engineering H180 Camshaft Sports Torque (nn) Any thoughts on this cam, good or bad?

Dr. Mordo, I didn't have a specific reason for the arms, but if you see the wear on the rocker shaft, I think it's fair to assume some wear on the arms as well. And beside, if you're in this deep why not?

1) Yes
2) Difficult but doable, follow master rover techs thread in the how to section.
3) Not sure, I went with an exact replacement so I didn't research any other option.

The important thing to note in all of this is that, in order to get the camshaft out you need to pull the radiator, trans cooler, oil cooler (if installed), and A/C compressor lines. If you're adventurous like me, you can lay some blankets on top of the engine and pull everything up gently fold the radiator, trans cooler, etc backwards and put on top of the engine to get camshaft out. (This way you don't have to deal with those Trans cooler lines that are a bitch!). Just be very careful not to puncture your radiator on any sharp edges. However, there is no way around disconnecting the A/C lines. We all know that's illegal to do in your garage and up to a $10,000 fine in most places. So have the A/C system drained at a shop before you begin this project, and just fill it back up at home once you're complete. Good luck!

Replacing the rocker arms is a very good idea when doing this much work. The rockers are softer than the shaft, but they start to wear out the shafts as they get older because any metal in the oil can get embedded inside the rockers on the bearing surface. The bearing ends up becoming a grinder from the little hard particles. The metal that was your rod bearings would be a perfect source.

When the shafts are replaced, the rockers should be replaced also for everything to last as long as possible.

Thanks for the answer. I didn't realize you had to disconnect the radiator and coolers. That's certainly a PITA. I knew the radiator would come out but assumed the trans cooler and condenser could stay in.
