Had the same issue as Julian did a couple of months ago. Scary because within the space of about a minute the pinhole in the hose sprayed oil onto the exhaust manifold, causing smoke to billow out the rear of the car and nearly emptying the sump. Lucky it didn't catch on fire. Yeah I was initially told via some Toyota parts boofhead that the replacement rubber hose was not available in AU and would cost some stupid figure like $600-700 to bring in from Japan, and would take about 3-4 weeks. After a few inquiries somewhere else we found the all metal replacement part off the Aurion. It was then that we discovered that Toyota recognized this problem on the Aurion, hence the all metal design. Moral of the story? If your Kluger still has the rubber hose fittings consider yourself lucky. But you are still sitting on a time bomb so get that part changed ASAP.
