Gave the bike a bit of a walk but getting nothing back. Took the return pipe off at the block and there was a drip. Took the prv out and again a drip or two.
I'm wondering if it's not enough to get the pump spinning to return?
It's been well lubed on the rebuild (top end only) so I'm wondering how long should I run it for safely before I need to shut down if I'm not getting any return?

With the PRV out you should have a fair bit (what would normally feed the crank) coming out. The feed side is blocked or the pump ain't pumpin'

Took the feed pipe off and nothing but a trickle.
Drained the oil from the tank and a lot of sludge in the bottom.
I think I'm going to bite the bullet and get a new oil pump too.

How would you reccomend cleaning the oil tank of the sludge?

Please - Take it off and wash it out with Paraffin (Kerosine?)
I read this thread with great interest - and had a look inside mine - You won't believe what I just found
A mystery solved, but expensive
Have a look at the Whitsend thread

Took the tank off and have it a swilling with petrol. Full of black gunk. Have left it soaking with petrol for a few days and will blow the lines out.
Glad I checked now!

Shaun , I think other people had mentioned about cleaning the tank out and I'm now going to flush mine out again. Just remembered how bad mine was when I first rebuilt the bike . You get all that work done and miss something so basic ! well at least I did ! Maybe just the fact that you want the bike to go and you get a blood rush or something. Mine had a considerable amount of fine dried dirt/metal that after the first run caused the rocker feed to block on my first run and I had a valve stick ,guite a push home . Stripped the top end changed a valve and all was well again .I had cleaned mine out and was convinced it was ok and clean but when I looked after the head had been done I found a considerable amount at the bottom which was at least an half inch deep . I had the tank  power blasted and dried and then changed the oil at least 3 times to get the residual shit out of the system which fortunately did seem to clear it all out . So forearmed is forewarned thay'll be my job during this week ,best wishes BobH

It's definitely been an oversight.
Concentrated too much on the outside of the tank and the paint job and completely forgot to see what it was like inside!

Sick as a dog!
New oil pump arrived and removed the worm drive gear.
Glad I did as I felt lift in the crank.
Strip down again and more expense!

I'm going to go and lay on a beach for a week to see if that makes me feel better.
Viva Espana!

Bugga.
Too many times I've seen a bottom end go just after a top end job has been done. If the top end looks sad with wear have a real good look at the bottom and check everything.
Look on the bright side Shaun. It's not as cold in the shed at night now (Nth Hemi) and once done you'll have a brand new motor.
Have a nice relax then get stuck in.
Cheers
