In my hands, those lines were impossible to access without taking the manifold off. Taking the manifold isn’t a difficult job but a time consuming one and you need to label all the detached lines. I labeled and took pictures of every line before taking the manifold off. I don’t know if anyone has any tips on repairing that without the manifold coming off...second time I removed the manifold was for TGV delete and fuel rail install. Either way, I’m pretty sure the easiest and cleanest way is to remove that manifold.
