What I am talking about is a poor fit at the sleeve to case drillings allowing oil to leak past the sleeve before it ever gets to the filter bore.

Oil passage from the pump to the filter chamber

Also on the subject of using and not wasting oil is fitting a #112 Viton o-ring to the I.D. of the pressure side of the bronze sleeve.
However, as to not to nip the ring much care need be taken to smooth and radius (slightly) the sharp edges of the plunger. Insert
plunger with lotsa lube and a slow twisting insertion.

I think what ClevTrev is talking about here is a professional way of doing the job as opposed to doing a bodge!
I am getting a bit confused here ...... doing what exactly???????
Stopping oil leaking around the outside of the oil pump sleave. Clevtrev's photo was of an 'o' ring groove machined into the outside of that sleave. I had not seen that mod before.
I have not heard of this either but it seems it would work fine so long as the ring can slide it without trying to roll out of the groove.... my memory is poor as I keep saying...... but is there not a bit of a taper just ahead of the actual bore?
If I remember correctly this could be smoothed up a bit to compress the ring as it sildes in..... once the ring is fully in the bore it isn't going anywhere. Getting a ring to stay put on a round surface may be tricky.

Trev,
What size O-ring and how wide/deep a groove?

1mm o-ring machined to give 5 thou of nip.
