Hi guys, I've tried searching through threads & haven't found any specific information on what I'm looking for.
Does anyone who has repaired their hydraulic system for the spoiler know the size - internal & external diameter - of the copper washers? I've got a slight leak from the banjo bolt.
I want to get all the parts together before I take it apart.
Thanks

You need exactly 12mm OD x 8mm ID x 1.5mm thickness or 1mm

Thank you!!

a man with some experience! you saved me from measuring one from the pile of hydraulic parts in my shop.

I'll see if this stops the leak Dave, otherwise I'll be contacting you soon for your electric kit

Probably won't since a lot of the issues is internal due to bad design. Mine worked for a bit but now inconsistent

Only two options to fix and utilize wing functionality. Rebuild/new system or electric kit.

of course I'm biased, but the hydraulic system and really the whole design is a mess. Only way to permanently fix it is with the eRam Kit.

Just out of interest, has anyone used stat-o-seals or dowty seals instead of the copper washers?

RennKit makes an amazing system...will be going down this route soon with their 4" lift system, Dave is Porsche enthusiast just like us.

I think it's called RennKit.

I've been trying to find a stat-o-seal or a bonded seal with the dimensions given by estrellajon, however, it's not been easy. The closest I have come to size is according to the chart I've attached.
DaveCarrera4 will one of these work with the hydraulic system, as I have seen there are no updated seals that have the exact dimensions of ID:8mm OD:12mm.
Thanks

Looks like an interesting idea, but I would first check chemical compatibility with the Pentosin PS fluid. Second, if the rubber swells or extrudes into the banjo bolt holes it will plug the system. I suppose the copper crush washers are the best solution. Since no type of Loctite or similar product can be used, all owners of OEM hydraulic systems should torque the banjo bolts at the ends of the rams and at the hydraulic plunger pump (4 bolts) on a regular basis as they can loosen from vibration. Once any is loose, the hydraulic fluid can leak out, then it becomes an exercise of trying to refill it and balance the system again.
