For years like a lot of owners here, I've suffered with this, the result of too many cold runs and not getting the oil hot enough. That I understand and for most of last year the small 100cc catch bottle collects only water from the tank breather, about 50cc every 200 miles. There is rarely oil or Mayo' in it. However, having pulled the one way breather off to clean after a fast 100 mile each way in lower temps (15-16c/60F) it and the breather were full of oily sludge. 3500 miles this year and have never seen such a mess. Since I'm going to treat her to new rings the top end will be apart and I'm thinking is it worth going further and doing the JC mod to add a lower drain hole in the timing case? Or am I deluding myself that if I reduce the timing side oil volume that might have an effect on what the breather is ejecting.
I have 850 cases on a 750, one way breather and tank venting to that catch bottle. Any thoughts?
