Speaking as a member of the Worshipful Company of Bodgers, would this not simply flare the end whereas the recommended fix (bodge) is to plate 3/8 of an inch which would give an interference fit throughout? We have to keep the bodging standards up.cbranni wrote:.
If your breather tube is loose in the stator when you split the cases you could heat the end of the tube put a centre punch in the hole and hit it, this will enlarge the end and you will have a better fit, it may be a bodge but..................

Re: Crankcase release valve
You are right Clive standards have to be kept up, I was thinking more on the lines of brutal, plating seems a bit complex, you can't beat a good bodge using heat and hammers
only dead fish go with the flow

Re: Crankcase release valve
Thanks all for your comments, Colin, the shims are behind the crankshaft drive gear not the timing gear and are listed as R (as req'd )
Many thanks. Paul

Re: Crankcase release valve
I fitted an improved crankcase breather way back in the day, but it needed a strip down and crankcase split to fit a new round gubbins onto the crankshaft final drive side.
