I have 2 PT Cruiser GT Convertibles, both lose hydraulic pressure. It seems to leak from the top left (driverside) hydraulic line. The o-rings seem to be dry/cracked. Anyone know what size these o-rings are? I've drilled a hole in the plastic holding tank and plugged it with a rubber plug for easy filling. Now I just need to fix the leak.

 

Hi
hope you can provide some help from your experience. Did you find out the o-ring size. I here is no specific information on the type of oil in the owners manual. Do you know what is best? Did drill a hole in the plastic and plugging work out well with no leaks? I assume the reservoir is not under pressure, correct?

thanks so much for any help anyone can provide!
