\Are you talking about the Spitfire 1300 or the Spitfire 1300?
Okay, I'll explain. The early 1296 found in Mark 3 Spits was based
on the original 1147 motor, which was based on the 9xx motor in the
Herald, etc.
The Mark 4 1296 and the subsequent Spitfiree 1500 was a completely new
design and block casting, using larger bearing crank journals and other
differences
with a modest amount of sharing bits with the 2.5 liter TR6 motor and
Mark 2/3
GT6 2 liter engine.
The later 1296/1500 engines did indeed have oiling issues. Read Kas' books,
the problems are not insurmountable.
