Need replacing, anyone on here done it themselves. I have taken all the inner wheel arch panels off so access looks fairly easy Let me know if it is a home or dealer job
For the main engine oil cooler, a special 30mm connector is used for the fittings, and it's sometimes referred to as a "Porsche oil cooler fitting". In reality it's just a large metric flare fitting that Setrab like to use on their oil coolers, but they're a real bear to find. When you get the gearbox lines off, take them to a really good hydraulic hose shop that is familiar with metric lines, and if the fittings aren't a recognizable "standard", do a search for the Porsche fittings and you may find what you need. I'm guessing the gearbox oil cooler is probably made by Setrab, same as the main engine oil cooler, albeit the gearbox cooler will be using smaller lines and fittings.
