Morning wammers, thanks for the info, is it a separate level plug because looking at the photo the OP posted you would not get much fluid in before it ran out. I don't have this problem, mine's a manual, my problem was the £2 spring pins that hold the release fork to the pivot shaft shearing. Who thought of that set-up?
You mean the roll pins or scroll pins. Never dealt with them on the P38 but have heard the stories. Think you can get them with a double scroll, one pin inside the other. James Martin may know about that.
