If I understand this correctly then you have a leak from the dipstick where the tube goes into the unit?

If this is the case and you have replaced the tube, then the issue is in the case being worn and not allowing a good seal.

This means you have a choice of replacing the unit or trying to seal this using a silicone sealant or larger o-ring to try and take up any imperfections.

If it were me, I would get a sealant and try and clean the surface and see if you can seal this rather than replacing the unit.

Please let us know what other questions you have and what happens with this.

Thanks
