[Closed] Reverb bleed question. Err, for a pal...

So, my pal, he bled his reverb (what a crappy job that [s]is[/s] looks like). When he'd finished all looked good until he realised that he'd bled it while compressed rather than extended. I mean, what a doofus! He seemed pretty fed up with the whole process at that stage and walked away from it.

To help him out, I though I'd ask how to go about bleeding it again now - does it need to have the bleed ports opened to extend it, thus filling with air to then be bled out. Or is there easy way to just fill with oil as it extends? He did try this briefly before stomping off.
