I had all the hoses off to clean, the top hose connector on the manifold was clear, but unsure of the bottom one, i managed to get my finger in to check the first cm or so but im by no means a contortionist so thats about as good as it gets!

I did the cap trick, it stayed on well but moved around a little bit, more to do wifh vibration though i think rather than positive pressureas at idle you can see the engine moving slightly, will test again post pre-mot work.

I should have pointed out that diagram is pretty much generic Tom and applies to most redblocks but the hoses can vary in length. What you say about a short hose would be right, it was about 2" on my 740s which were all B230E engines so slightly different to yours.

Contortionism is a necessary ability when working on Volvos! It seems though from the cap test that the oil separator is clear which is a bonus. If you haven't already done it, an engine flush followed by oil/filter change will help. As for the rest, wait until you've got the dizzy cap, rotor, HT leads etc done, also check the plug gaps (0.7mm) and consider renewing the plugs unless they've been done recently and get the exhaust sorted before you go chasing your tail trying to find that elusive last bit of smoothness at idle.
