So I bought an E30.

Dammit Jeff, get your head out of your ass.

How charming. Upon further review I can see what you are saying, I should have done the research.



I hope that link stays alive. Anyway. From looking here I don't see any reason to leave any fluid in it at all. I think it was Evan who said above that most Miata guys just run them empty, which makes sense to me. No reason to vent the damn thing either from what I see. The actual rack and pinion will work fine, I am assuming from the picture there that the p/s fluid in no way interacts with the actual steering gear. So all leaving fluid in it would do would be lubricate the piston as it passes though the tube and keep the now useless (as you point out) seals moist. Would the tolerances be close enough in there to compress air in each side of the piston? I would think it would be minimal if at all.


EDIT- But I digress...it seems to not matter because we have at least one person on here saying each method has "worked great for years!!" I'm gonna stop shitting up Rex's thread now...Sorry buddy!
