1979 300D start problem

Submitted by TaC on 24 August 2008 - 1:45pm.

1979 300D. Stored for 4 years won't start without the block heater when it is below 60 degrees. The oil was not changed during storage. Glow plugs appear to cycle. Does anybody have any ideas? I am looking at purchasing this car but want to avoid a big engine problem.

Thanks!
