Excess oil also helps to foul the catalytic converter!

WOW!!!   You just answered a question I've been waiting to ask the list.
I've been getting the oil pressure buzzer and light after a run on the
highway as I decelerate on the off-ramp.  Goes away when I accelerate,
and doesn't happen at all around town.  Coincidently this started after
my tech replaced the oil cooler seal (had a leak).  It's all very clear
now..they overfilled it.  The buzzer/light doesn't happen much...should
I just let it burn off or should the excess be removed?   The dipstick
shows very little overage...just topped off.
Thank you sooo much for solving this little mystery!

Usual causes are overfillitis or piston rings not doing there job. Some
oil vapor is normal. But if you get massive amounts into the intake
track, something is wrong. Keep the oil level between the marks on the
dipstick Do not attempt to keep the level at the top mark. The top mark
is not the full mark. It is the maximum do not ever exceed not matter
what mark. The Vanagon engine is extremely sensitive to overfilling.
When over full, oil temps go up, viscosity goes down. Oil lights and
buzzers get tested after long highway runs. Very high speeds make thing
worse as while the viscosity goes down the temps go up some more and the
vicious cycle goes until you get the buzzer or a rod out the top. All
this while the water temp is perfectly normal.

to have oil inside the AFM body? I just took mine apart to fix vacuum
leaks
and found oil all over the place. Shouldn't there be some kind of
one-way
valve between the crankcase and the vacuum hoses?

Cleaned it all up, of course, but what will stop this from happening
again?
