I am looking at this thread with interest as I am just getting to this stage of my reassembly. My 86" has an oil filter very similar to those descibed above.
Is there any way to tell the difference between a R3P & R4P unit other than by date of use? Mine has a 13/16" hex head on the top bolt. The filter cartridge looks pretty much identical to that posted by Chazza.
It is attached to a bracket welded to the chassis which follows the profile of the inner guard.
As for the the pipes that the service the filter, mine has 1/4" copper tubing which I have to replace. Is there any advantage in trying to go to a larger diameter tubing & fittings??
No problem getting a Ryco R4P oil filter. My local car parts shop keeps them on the shelf. This filter housing was standard fitment to Champions' 80" Land Rovers.
