"What have you done to your Range Rover today?".........."F*cked it, mate!" - well, it certainly isn't going anywhere in its current state.
Before that though, yesterday was finishing off the rear suspension. That all went pretty good to be honest. Two exceptions.
Firstly, the bottom nuts that came with the shockers. They are made with some sort of integral lock washer (not nyloc). If you try and tighten them using two spanners - 6mm and 19mm - you'll get nowhere. The nut requires a lot of torque to tighten, and the little 6mm thing on the end isn't good enough. It's a case of grabbing the shock body with some grippy gloves on, and running the nut up with the windy gun. Well, that's fine, but what happens if you don't have one of them? I never used to. I'd have been really p!ssed off trying to fight with that. Grrr. It's a non-standard, finer thread, so I couldn't just use any of my nyloc ones. I get that this all makes sense on an assembly line, where they all have power tools to hand, but it's a bit of a pain for the poor sod who tries to do the job afterwards, lying on his (or her) garage floor.
Secondly - more entertaining! As Strange Rover said above, the EAS sensor on the OSR is 'fuckered'.... definitely!
The bit that goes into the radius arm...... just half disappeared. I had to drill into it, tap an M3 thread in and then put that into the arm.
So far, so good. Then the actual sensor part just cracked and fell out of the chassis.. had to tie wrap that back into place...
And then the lower arm kept popping out of the rubber 'elbow' swivel. Had to hold it in place with an R clip.....
I wasn't planning to cross the Sahara - just get it out of the garage and turned round without throwing a faulty fit - but it was still all over the place. They don't make things like they used to! Anyway, it's all on, doesn't appear to leak, and I'll get some new ones and make up a set of calibration blocks.
Then I moved on to the infinitely more interesting task of stripping off the top of the engine. You've seen the pics before no doubt, you go from this
This is where I left things. Covered it up, and closed the garage. I have a little parts list to sort out before phase 2 - taking the wing liners off and tackling the exhaust heat shields and manifolds before lifting the heads themselves.
I started this to tackle a coolant leak, at the back of the valley gasket, and having got this far, it's good to see that it does still look as if that was the source. Both of rearmost bolts, (L&R) where the inlet manifold goes onto the heads, were barely tight at all. Finger tight at very most. Same for the rocker covers actually, barely tight at all. It's not so obvious in this pic to be honest, but there's definitely red traces of coolant at the back there, and onto the top of the bellhousing.

I quite enjoyed myself today, to be honest. It all went more or less by the book. I think the only casualties have been the hoses to and from the heater. They were well bonded on. I decided life was too short to muck about with them, and cut them off. Oh, and I had to go to Halfords to get a bi-hex long 8mm socket to take the rocker covers off. I thought I had all the tools I'd need, but there's always something.
So the questions (there's always questions!)
Different colours inside the rocker covers. Right hand (left hand in the photo) is darker; pass. side noticeably lighter. Does that mean anything?
front end of the RH head gasket - does this look like a leak? And did they scribble on them in marker pen in the factory??
So far, so good though. Without pushing myself too hard, it's all coming along OK. Of course any monkey can take things apart, the fun starts on reassembly, but that's for another day.
