So let me give you a quick history of my "new" 89 Vanagon GL.  So far I've
replaced the heads, water pump, the pipe that connects the pump to
thermostat, temp relay in the radiator, temp sender, and finally the
distributor.

Now here's my new problems.
1)  On a drive from Flagstaff to Moab the oil pressure light and buzzer come
on once the engine is heated up quite a bit, it only happens when going up a
hill and the RPMs drop below about 2600 or when slowing down when
approaching a town and again the RPMs drop down.  As soon as the RPMs go
back up (downshifting) the buzzer and light go back out.

2)  The idle is all crazy.  When I start the engine it does better but after
warming up it really starts to jump around a lot until it dies.  Also, when
I come to a stop and push the cluth down the van cuts out also.  Everytime
it does this it just fires right back up but the idle is still all crazy.

3)  The van seems to be running a bit hot before the fan turns on.  I've
seen it go up to about 7/8 of the way up before the fan comes on.  Now I
thought that replacing the relay in the radiator and the temp sender would
alleviate this (of course they were both bad anyways so they had to be
replaced).  Coolant isn't leaking anywhere.  I'm just getting kind of tired
of driving through the desert with my heat on full blast.

Any suggestions on what may be the problem or if this thing is safe to drive
back to Flagstaff (about 300 miles) would be greatly appreciated.

Matt
