Subject: Re: Lagonda 11.9 crankshaft oil sealing or lack of
Just to stimulate a little debate around the effectiveness of the early cars splash oil system...
The late Arthur Jederre-Fisher recommended raising the level of oil in the two sump troughs by 1/8 inch. This was achieved by drilling and tapping the drain hole in the centre of each trough and fitting a 1/8 or 1/4 BSP reducing bush and cutting it down to achieve the raised level. The hole in each bush may need to be drilled out to a larger diameter. (Thanks to Ken Painter for this extract from Arthurs J-Ds note books)
I guess this was one improvement to overcome potential oil starvation for No 1 and No 4 big end on hills?
Are there any views on how effective this would be and whether there is any down side?
Thanks
Mark
