Subject: Re: New Oil Pump 2.6

---

There is work on the block to reduce the unwanted back presure which destroys the scew gear drive. The face
that the pump bolts to needs to be opened to match the
exit opening the oil pump. The hole needs to be milled to
the depth of the transfer port below, preferabley with
a bull nosed cutter, or blended with a die grinder. Next
the transfer holes forward, and the two to the oil filter
tower, all need to be bored/drilled to 14mm. Be careful
on braking through into the the transfer drilling, not to
touch the oil presure relief valve port oposite. Next the
oil pump tower needs the same tretment. These operations
will require tapping for larger end plugs. The oil filter lower
and upper holes at 90deg to the vertical holes, need to be checked to make sure they line up to the block and the
filter housing. Make sure the gaskets don`t mask the
drillings. Last of all if you have the old rotary oil filter
copper screen type they can be coverted to a modern
paper type.
