The fittings have no rust on them and the lines don't appear to be leaking at all. They look to be in good shape, and I've never heard of one on these just suddenly failing without any symptoms first. I don't know how bad of a job it is with a 603, but with a 617, I don't want to even consider if it's not necessary. The worst part about it though, is that it will still leak elsewhere. There is oil covering the little round thing under the turbo. It has a rubber hose with a hose clamp on it, but that whole area down there is covered in thick oil. My turbo drain isn't leaking, I know that. That piece and below it are clean. I've already replaced the oil pan becasuse it was cracked, and eventually was leavig a pint of oil on the ground everyday!
Thanks
David
