I decided to replace the oil filter in the right side engine cover with a remote spin on filter. To do this I had to modify the right side cover. The right side cover houses the oil pump, the pump pumps oil up a 10mm gallery to the front of the cover which is stoppered with a bung. a cross drilling from the gallery leads to the filter in the right side cover, then on to the engine. So, to effect the mod, I had to remove the bung at the front of the cover, drill the gallery out to 10.8mm, thread it M12 about 40mm deep, then machine up a long threaded barb that screws into place covering the cross drilling to the right side cover filter. Drilling the gallery was a job in itself as the gallery is offset on two axis' so, after mounting the cover on the pedestal drill table the table had to be offset as well to align the drill with the oil gallery hole.
A spin on filter mount was then machined up, along with a threaded filter retainer, then a threaded barb was machined up that screws into the filter retainer, thus sandwiching the filter mount between. A barb was then machined up and pressed in to place next to the threaded barb for the oil inlet, as there was insufficient space for a threaded barb.
To mount the filter mount, I had to fabricate a couple of aluminium front engine mounts with an extension at the bottom on which to mount the filter.
While I was at it, I decided to add an oil cooler. A bracket was made that bolts to the front of both engine mounts and the cooler mounted to that via some long 10mm aluminium tubes and four long M6 bolts. To counter vibration, I installed four rubber gromets in the cooler mount. The cooler is mounted with the inlet and outlet facing up, so oil doesn't drain from the cooler to the engine when stationary.
For the feed back into the engine, I machined up a cover whith a raised section into which I pressed a barb, Looks much better than just screwing a right angle barb into the original filter cover.
A rubber hose connects the barb on the front of the right side engine cover to the inlet barb on the filter mount, similarly, a rubber hose connects the outlet on the filter to the cooler, and another hose connects the cooler outlet to the new right side cover inlet.
So, the system now works thus: the oil pump pumps oil up the 10.8mm gallery, bypassing the cross drilling to the right side filter and exits via the barb on the front of the cover. It is then fed to the inlet of the filter, then from the filter outlet to the cooler, then out of the cooler to the now empty right side filter recess, then on to the engine.
