Is it just me, or is there trouble retrieving information from the archives? I was unable to get into them at all, other than the first page.

We have usually had problems with the oil light buzzer on our 88 Vanagon GL after we drive quite a ways up a mountain/hill.  We have always just stopped, turned the engine off, and then restarted with no problem.  Now, whenever we drive on the freeway about 20 miles or so (flat, level area), at normal freeway speeds of about 65, it always starts buzzing about 1 block off the freeway - going and coming home.  Any ideas on why this happens?  This has happened quite a few times in exactly the same areas and distances.
