Re: Problems with new Rover 4.6 Engine
get a wideband on it to see what actual mixtures are doing ( assuming you've already checked fuel pressure too )
Is there any adjustment screws on the MAF, what design is the MAF on those ? Is it an old flapper or something more modern ?

Re: 3.9 EFi Fuel Rails?
That's very expensive, have a look at OBP https://www.obpltd.com/product-category/fuel-water-swirl-pots/bulkhead-mount-swirl-pots/ I would not bother with any that then rely on an external pump. Just gets messy with lots of hoses and fittings, and takes up more room anyway Whilst Nuke or Radium, we...

Re: 3.9 EFi Fuel Rails?
I have 3.9 V8 EFi which has a couple of solid lines with braided 6" connectors to allow some flex I guess? One supplies fuel from the std pump in the tank, with the other returning it back to the tank. I have had problems with fuel starvation when the vehicle is tilted to around 45 degrees. It...

Re: Flywheel issue
What do you mean it isn't engaging ? The splines don't engage ? you've no drive ? you can't select gears ? etc etc
Stick a small borescope camera in there to get a look.

Re: Problems with new Rover 4.6 Engine
The injectors have clips that secure into the rail, you can lift the entire rail out and crank with injectors all pointing into jars.
Although whether that's easier than just swapping to different cylinders and re-trying...debatable. But sometimes a visual can help.

Re: Problems with new Rover 4.6 Engine
Noid light shows that electrically 4 and 6 injectors are getting a firing pulse So if you are sure they are getting a valid signal, then swap those injectors with another cylinder. Or if wiring reaches, swap wiring from a good cylinder, to the bad cylinders and see if it moves. Also confirm you hav...

Re: Vitesse box in p6 speedo inaccurate
Similar was available commercially a lot of years back for the mechanical speedo jap imports, to convert their kph speedo's to read mph.Clyde Archibald wrote: ↑Sat Aug 23, 2025 4:51 pm Thanks man. Interesting about the 3d printed gearbox
DIY 3d printing....cool new version if you can do it.

Re: Vitesse box in p6 speedo inaccurate
Is it cable or electronic ? I think there are drivewheels with different numbers of gear pinion teeth ? or if electric, which is easier, you can buy electronic correction boxes. Although it says not available...I'm sure there are others out there https://www.jaycar.com.au/speedo-corrector-module-for...

Re: Ignition advance with ECU controlled ignition - Should it be this high?
Depends how you are determining "want" ? At light loads, higher tiing figures would be fairly normal, aka vac advance, light cruise etc. How was this table created ? on a dyno to see what the engine really wants ? Or just best guesses ? At those load sites, what is manifold vacuum like ? O...

Re: Ignition advance with ECU controlled ignition - Should it be this high?
Have you verified base timing ? ie, flatline timing at 0deg, 10 deg, 20 deg and check/confirm with a timing light ? If you're a wasted spark system bare in mind a dial back light will read double. Hence testing at various levels is essential to see any odd behavioural patterns. 35-50deg at idle, is ...

Re: Rover V8 quad Turbo
Hello, I got my hands on a Rover V8 ALBERT Turbo years ago. In similar condition. https://up.picr.de/35696600dq.jpg https://up.picr.de/35696863xi.jpg https://up.picr.de/35696919ph.jpg But four turbos seem a bit much to me.

Re: Rover exhaust thread repair
Looks like you'd have room for a flanged nut maybe ? ie https://www.westfieldfasteners.co.uk/UNC-Nuts/Flange-Nut-Hex-Serrated-UNC-3-8-inch-A2-Stainless.html ALthough stainless vs not is debatable. Stainless can be nice, but a bugger if you drop it and need to use a magnet. I've been moving back to r...

Re: Rover exhaust thread repair
Helicoil definitely the easiest and best option.
Kits are cheap too and always handy to have, and will let you retain your existing thread size.
I think they are 3/8 unc ? Don't recall them being 5/16"
