Log Splitter Breather Cap

[ColdNorCal]

Bought a 32 ton Dewalt splitter and noticed it does not have a breather cap. Instead it has a solid bolt. Seems that with fluid expansion due to heat this is a bad design. Should I find a breather cap?

Update: Looked at a couple of TSC CountyLine splitters and they do not use a breather cap either.

I was curious. It appears there are totally closed systems that are sealed. Then there are systems that use a reservoir. They have filters to allow only dry air in and out as the volume of oil goes up and down.
