You won't be able to tell if he is being honest.

Oil in a radiator is a sign of a blown head gasket.

A blow head gasket requires the following to repair if the head is ok and not warped.

  • Remove all fuel injection or carburation.

  • Remove intake manifold

  • Remove exhaust and manifold

  • Remove valve cover and cam sprockets (if it's an overhead cam)

  • Remove various sensors or connecting wires

  • remove head

Then do the work to verify the head is good and clean everything up. Get the head rebuilt or do it yourself. Hope the head isn't trashed.

Stay away from it.

I won't go into a morality speech of the seller other than, run from him and move on.
