I Just replaced SLS aCCUMULATORS ON MY NEW 80 TD,bled and filled with OE Febi H fluid,however the reservoir seems to sweat or slowly leak around the cap,is there a o ring there or do these need to have the cap replaced?
Thanking you in advance

there is a o-ring/gasket in there. I think you have to buy the cap to get it. I got a better one than the one I had on the car from the scrap yard.
