The 50 degree mount angle requires a diesel Vanagon oil pan AND oil
pickup tube. I assume the mechanic knows this and is using the right
stuff. If he is using a used diesel Vanagon oil pickup tube then that is
the likely problem. The oil pressure relief valve is built into the
pickup tube. If it came from an engine that failed small bits of engine
debris may be jamming the relief valve in a partly opened position and
then the oil pump sucks air at low rpms. The oil pan must be removed and
then the pickup tube can be removed for close inspection. I have seen
this problem twice.
