Replaced one of the post-cat lamdbas. PITA to get it out, but a mixture of ATF, acetone, heat and impact wrench did it in the end. :y
Blimey Kevin... You're clearly taking the whole MoT thing quite seriously  :D

EML is a fail now, IIRC, and given that the heater in the sensor was open circuit, it didn't take that long for the ECU to realise that it was shot following a reset. ::)

Stupid German automotive "engineers" cars...

FTFY.. Jesus! Batteries fail. People jump start cars or shove a new battery in when that happens. Normal cars just work when you do that. A car that can't deal with it is not fit for purpose.  ::)

I think you need to measure the oil pressure properly with a gauge.

I won't get hot enough to lose oil pressure without the coolant boiling over, at least with the modern synthetic oil it used to have in it. Who knows with dead dinosaurs? ::)

I wouldn't be surprised if the fan doesn't kick in until 100 degrees C or more, and who knows how accurate the gauge is?

It's telling you the oil pressure is low so that's what you need to check.

I had a hospital appointment this morning and cycled there. It was a bit cold, but comfortable at -4degC where the exercise keeps you warm. :y As soon as I got into the hot hospital I started sweating buckets and the pads for an ECG kept falling off. ;D Anybody that knows Frimley Park Hospital knows it's cardiac outpatients is like playing Crystal Maze to solve the problem to understand their trail of cryptic signs. :-[ :-[ Fortunalely I arrived 15 minutes early and won where I ended up in reception with 2 minutes to spare. :) 8)

Didn't have to remortgage to pay for the parking either, presumably. :y

Speed limits are set conservatively enough these days that anyone who doesn't end up feeling comfortable at within 10 MPH of the limit probaby needs to be on a bus, IMHO. If only for the potential to cause a lot more overtakes than is necessary.

Doctor Gollum,  how can you tell if out 180?

By checking the positions of the cam lobes at the TDC position, as described in my post above.^  ;)

I should have said, regarding the Haynes advice regarding cam lobe position, it's best to ignore it.

The TDC markings are the correct reference, and these occur when no.1 cylinder is at TDC at the end of the compression stroke. This means that on No. 1 both cam lobes should be away from the followers (but neither will be straight up!), and, on No. 4, both lobes should be partially acting on the followers (inlet opening and exhaust closing).

Firstly, make sure the crank is turned back to 90 degrees before the TDC timing mark to ensure you don't damage anything while fitting the cams.

You will need to turn them to the TDC mark and then lock them in place. Do you have the locking tool used for cam belt replacement. If not, I would get one before proceeding further.

Often there are flats on the camshafts that you can place a spanner on in order to hold them in place. The valve spring tension will act on the lobes and cause them to try to move, so maybe get an assistant to slip the locking key in while you hold the two cams in place with a pair of spanners?

If you haven't removed the sprockets, it strikes me that you won't be able to correctly reinstall the camshaft seals?

Once you have the cams locked at the TDC position, then carefully turn the crankshaft up from the 90 degree before TDC position until the TDC mark lines up, then proceed to install the cam belt as you would when changing the belt.

Converted mine at about 70K, if memory serves. It's now on 230K and still sweet as a nut. I doubt it's done more than a couple of K on petrol (plus warmup time) in that period. So yes, go for it. Get a decent SGI system (many of us have used the AC Stag systems) and you can't go wrong. :y

I do hope they remember that a key part of the punish^h^h^h^h^h^h rehabilitation process revolves around Big Winston knowing exactly why he's in the slammer. >:(

Range Rovers certainly feel like you only have to go round a corner at above walking pace to put them on their side. Are we sure there was a second vehicle involved? ;D

Should have PM'd this.
Info has been passed to the OP via PM. :y

A 20% difference in hot viscosity isn't going to be the problem, especially in the middle of winter.

Agreed that a manual pressure gauge you can check it with would be ideal, but, if it's genuinely got no oil pressure, then it's probably already far enough gone that it doesn't matter. :(
