At a guess, it may not be the length of the spring that counts but the pressure it applies to the bullet..? Logic would dictate that the aftermarket manufacturer of the new pressure relief kit you bought would know what poundage set up was required for a Rover V8 relief valve..

Never having tried to pressurise the Rover V8 via the pressure relief valve, I can only suggest again.... It may just be possible that if you make use of a pump feed oil can filled with engine oil, and hopefully a flexible nozzle tube may just provide you with access to the oil galleries.

HOWEVER, with the bullet/tadpole removed, it seems obvious that you will have opened up not only access to the oil gallery, but also the orifice through which the over pressured oil would normally drain..?
The above is why I suggested IF possible removing the oil pressure sensor as being my choice. All assuming access to introduce oil is possible at it`s location relative to all else around it.

Again using logic and no more. It would seem the oil gallery as opposed to the drain to sump within the oil pressure relief valve would be acting on the nose of the bullet/tadpole, which would be directly in line with the line of the spring..

Again assuming the nose of the oil can can fit inside the bullet`s housing and make direct contact with the gallery drilling, then I fully expect you will be able to introduce enough oil to the pump to prime it. and if you wished as an extra guide, you had someone with the ign switched on they could perhaps see the oil pressure gague needle rising..?

Against the above would be if you could only get the nose of the oil can into the start of the pressure relief valve orifice, which would then cause whatever oil you were able to pump in with two routes of escape, one being the target gallery and the other the relief passageway.... That typed you may even by that slightly flawed process introduce enough oil to the gallery to prime the pump...?

As for sealing while pumping oil... When I first tried this process in my yoof, as i previously typed I used a bit of rag wound tound the oil can nozzle jammed into the oil pressure relief valve assembly to cut down on the mess and help reduce pressure loss created by the pump action of the oil can.... It worked for me..

Wishing you the best of luck Jeremy..Fingers crossed..
