Oh and the front camshaft bearing is positioned to blank off the oil hole. All of the crankcase plugs are loose and removed one at a time to flush any dirt out and it's surprising how much dirt appears in the bottom of the tray from a crankcase I had cleaned. I usually change the paraffin for a second go. Wellington boots are optional extra PPC.
In all seriousness, anyone who saw me hobbling about with a stick a couple of years ago at Beaulieu may be shocked to learn it was the result of getting my left sock splashed with paraffin. I was 'busy' at the time so ignored it for an hour or two. My foot inflated like a ruddy melon. Have been dunking stuff in paraffin since time began so don't know if I got some 'bad' stuff or perhaps have become sensitised after all these years.
This sounds like a good approach to me (I don't use splash feed!) but it makes me wonder all the more about how the heck the big ends get lubricated at all on a cold morning start (in which condition oil ain't nearly so runny as paraffin).
Another thing to consider when uprating oil pumps is the rating of your pressure relief valve spring - easily forgotten component!
