Steam Clean the engine, or presure wash it and locate the source of the
leak.

You'll be happy you did it right.

Get the hoofmobile out for the weekend  if you don't have the time nor
the right equipment to get he job done on your own.

I guess you really don't have much of a chioce.

A�couple of 6x6's and some 2x4's make dandy ramps you could back up
onto for this task.
But you don't have the time.

<<The van is back at the local shop, who are checking again, but say
there's so much oil it needs steam cleaning before they can tell much.
That's not possible before the long weekend so any insights would be
helpful. My other car has just split its radiator so maybe the weekend
will all be walking.>>
I should be under the van myself, but work's getting in the way (and I
don't have risers or a lift.)>>
