Re: Intermediate cover
No, the intermediate front cover uses a coolant pump designed for the serpentine belt - which runs on the back of the belt so runs the opposite way to the V belt coolant pump.
To use a V belt crank pulley - you'd need to change the whole front cover to the older cover.
If you need a new crank ...

Re: Rover V8 3.5 rebuild – 9.75:1, Kent H200, Flapper EFI
If you're going to all that trouble I think I would also be looking at upping the displacement - can't really beat more CC for lower end torque (apart from a supercharger!).
For a landrover you need off idle torque, personally I would favour the H180 - though displacement helps tame a sportier cam ...

Re: How easy is it to dry sump a serpentine belt 3.9 EFi?
When I was 'musing' about "is it worth it to look at doing a DIY dry sump", I found it very visually useful - to get my sump, and fill with 'fluid' with the pick up roughly the right place, and literally tip the sump back and forwards to see how the liquid responds.

Re: Helicoiling the head bolt holes in the block
Now the question is ....do I do all the holes or just the stripped ones ......thinking that the p o had torqued all the studs and anything not actually stripped was likely to be close to stripped . Im inclined to do the 20 main holes as the p o did state that the other 8 ( along the outer edge of ...

Re: Helicoiling the head bolt holes in the block
I also had a stud pull out when torquing my ARP stud nuts down - so I did a helicoil by hand, using a second set of eyeballs and a couple engineers squares and it worked fine, though neaveracking! Used a two helicoils so I had enough thread engagement.

Re: DAX Cobra cooling
Yes, good point Ian, flow through these smaller pump inputs is by-passing the rad/stat, so will reduce cooling potential.
This bypass circuit is important when the stat is closed, to keep some coolant flow through the engine - but also important to limit this flow to give the rad the best chance of ...

Re: DAX Cobra cooling
The two small ports on the back of the coolant pump are both inlets.
Linking them together is fine, but neater to just blank one off.
Probably a chance for air to collect in the top of that copper jointing piece.

Re: Rover V8 4.6 fit top hats or not
What do you mean - "it doesn't have liners"? Has someone removed them? as all RV8's have iron liners.
I rebuilt my 4.6 - had the same questions on liners.
I had the block pressure tested and found 3x were leaking so that was an easy decision for me in the end, to go with top hat liners and never ...

Re: John Eales crank damper, oil seal journal eccentricity
Seal runout allowance greatly depends on seal type - and shaft speeds.

The thermostat housing and inlet manifold base.
Someone's modified that - it's not how GEMS were originally.
