For those interested with Early 1.6 or 2.0L engines while i had the camera out today i took a few shots of the Oil filter mod on my 53 model. These are available from the Series One Club Shop in the U.K. Quite Expensive but worth it when you get past the 4th or so oil change.
It looks like the early bypass filter at the top but from the bottom its just a standard cheap as chips $15-20 Ryco Z418 / Valvoline V022. Makes changing the oil a breeze.
