I don't know if I can help or not, but I will try. I am afraid that I can't help directly with the leaks because while I have had several problems with my Franklin leaks are not among them. 

I am very concerned about the oil temperatures that you report. The Franklin manuals list the maximum temperature as 230. When things are right, even when breaking in the engine, the oil temperatures shouldn't be greater than about 220.  Incidentally, If you have to break in the engine, 24/24 will not do it. That is only 63% power which will almost certainly give you glazed cylinders. where are you measuring the temperatures at? It makes a considerable difference. What are your oil pressues? Low oil pressured are a strong red flag.

What are your head temperatures? It may be a generalized cooling problem. The engine cover that Velocity supplies for cooling the Franklin fits rather loosely and the engine temperatures can be brought down considerably by plugging up the air leaks and generally tightening up the baffling on the cylinders.

I have a SRG Franklin/IVO with 3hours and 15 flights. First I had high oil temps(+250) on climb out and would not cool.
I went through all archives and mods back 1995 and made all changes. I now have oil temps below 250 if I dont exceed
24 MP/2400 rpm. Each flight results in dripping oil on the floor before I can get out of airplane. Oil looks  like its coming from
the fuel pump and alternator plate. Iam on my third set of gskts and still have the problem. The oil may be comming from
the the distributing zone (air intake that carb bolts to) it has 2 long bolts that have no seal that I can tell.

After five months of fighting this engine I guess Iam begging for help.
My Ft. Collins Franklin dealer doesnt answer his phone.
