i tried this tonight and it stopped them leaking... then gave them a spray and it started again.. got a bucket under them just now. Im wondering if it's to do with the position of the bottle plus i think my car is lowered at the front but i don't know by how much as i replaced the original struts with ones i bought from ebay. They came with green springs and obviously original springs are black. they are an option on the mk2 ghia and other models in Switzerland, germany and France i believe. I bought them off ebay because they looked quite cool.
