sorry for the introduction with problem included.
I was hoping to introduce myself in a more positive light...
oh well.
I have very recently bought a BJ42-

Got it freighted from Brisbane to Melbourne-
took a gamble and only had an uncle test drive it and inspect it (rather than a mechancial survey)(With many long and detailed conversations with the PO and his father)
the truck looks great body and underneath, drove great (for my uncle) and does appear in genuine good condition.
As it happened, the BJ drove onto the truck in Brisbane, but one week later in Melbourne wouldn't drive off.
The freighters tried to jump it with 2 starter packs- and couldn't, and then dropped it at my place.
The battery proved to be dead (only charged to 10%)- and a new one didn't solve the problem (it barely and intermitantly turned over a couple of times and then stopped- with just the relays clicking).
I pulled the starter motor off, and discovered that the wires for the brushes were loose- looked to have been badly soldered, and had come loose/melted loose.

New starter will be had on monday hopefully.
Anyway, today, for the icing on the cake, I dipped my finger into the top of the radiator and it came out covered in oil.
The top little section under the cap has about 5-10mm of milky oil on the top.
I drained some oil out of the sump, and thankfully there is not water in that (no milkiness- and no bubbles when doing a hot pan test).
so-
any ideas or advice would be greatly appreciated.
Headgasket- something worse- something better?
Cheers, and hello- wish it was under better circumstances.
Hans.
