A possibilty I had entertained Dave, BUT, the block edges in all the water ports are in beautiful condition, the cast iron as a whole is still un stained with rust, and the ally parts are in un-oxidised condition. It has had coolant from us regularly(Every 20K, plus the odd 'P' gasket and replenish in between) and until we started looking after it, had been well dealer serviced as far as I could make out. If it was any kind of corrosion/ electrolysis I would still bet that a casting fault was there in the first place to allow it to eat through so quickly.

given its that clean, any chance its had an overzealous acid flush put through it? (there must have been a defect I agree but what was the accelerating factor)

How did the Goldfish get in there?

jumped out of the windshield washer bottle.


duh.....

Not sure, I know I've never done it. I guess now is a good moment to mention the OTHER time I've come across a casting defect. It was in a 1998 FL1 2 litre diesel. it had a drip, like a leaking core plug, coming from the front of the engine, (against the firewall side.)and it was a steady drip. On further investigation it appeared to be an external leak THROUGH the cast iron block I touched it with a small screwdriver and a piece of cast dropped out and the leak became a 'run' . After a while and a consultation with the owner, I decided that the best method was to see how 'big' the effected area was with the view to plugging it, as the only other fix was replace the block. In order to get back any kind of wall thickness, I had to die grind it out to about 10mm, then tap a 12mm thread and fit a screw in plug and copper washer. This repair is still fine, after 5 years or so. In that case, it was most certainly a casting'bubble'.

I'm pretty sure Serg/Uninformed said he'd seen something like that (maybe two ??) in a workshop in Brisvegas (Ricks ??) after his Defender did the head and cooked itself a year or two back.
Basically ****ty casting quality/core shift.

Must be a UK (or Holden ) thing.
I've actually seen a similar thing on some AP Racing disc rotors
I started using DBA rotors cast here after that......

At least the owner can be sure its in capable hands.....
