When cold the oil is thicker, allowing less oil to sneak past the failed seals. When hot the oil is thinner, allowing oil to pass thru the failed seal easier.

The HPO pump can develop up to 4000 psig. Makes it easy for a "thin" fluid to leak out of a small hole.

Hydraulic systems (which is what the HPO system and the injectors are) operate on high pressure / low volume pumps. A small leak will make a big impact on the hydraulics.

Oh, thanks for the info. I understand a little better now. It still confuses me but that is why I'm not a mechanic.
