The VW dealership called. They called Lisa's father because when I gave them my number, they didn't write down my area code and thus tried to call 503. Fortunately, they have his number on file with the records for that Vanagon, since he actually owns it and they've worked on it before. Anyway, they say the leak does indeed appear to be the oil cooler and seals, and while the parts aren't too expensive, there's a lot of labor involved. Estimated cost of repairs: about $1,050. Urk.
But it needs doing because right now, Lisa has to stop every hour or so and pour another quart of oil into the engine. Beyond the risk of engine damage, the mess it makes on the van, and the ongoing oil-replacement costs, there's the matter of leaking all of that oil being environmentally unfriendly. It's no BP oil rig, but that doesn't mean we should keep doing it. Current Mood: sick
