Another Oil Cooler/warmer Removal Thread

[unlimitedpower]

I know this has been covered 100 times already and i have done extensive searching,
I understand the process of removing the stock oil cooler/warmer, linking the water coolant lines together etc,

Then fit a RB30 or L28 etc oil filter thread into the block, Or a RB20 oil filter tree,

What i am worried about is the bypass valves, (two in my cooler)

On engines with coolers the valve is in the cooler and on engines with out coolers its in the block,
From what i can tell everyone seems to ignore this issue,

Is it a matter of swapping in a bypass valve from say an RB30??

If so does anyone have the Nissan Part number for the valve, My mate only has the Japanese Nissan Program and can't look up Australian assembled vehicles,



These are the two items im talking about. As above it seems most people ignore the valve.

I know some people just use a filter with a bypass in it but im pretty sure that these actually do the same sort of job in two completely different areas,
One is in the filter circuit and one in the block circuit.
