My beloved scoobs is a rather unhappy fellow at the moment, with a very sick engine.
From what I've managed to peice together, the story runs as follows (I started a massive essay for you all but figured i'd give the abridged version!):
A radiator hose split while in the mountains, used duct tape to seal small (<3mm) split in upper radiator hose. Heat melted tape's glue after 200kms back on freeway. Let engine cool, topped up coolant with water and re-taped hole. Made it to seymore on the Hume to subi dealer, replaced hose and bled system. Made it 15ks out of seymore all good, then no power in acceleration, temp guage spikes with steam coming from below engine and radiator cap cool to the touch. RACV flatbed back home
The cause:
From what I can figure two things happened. 1) a massive airblock was stuck in the engine after replacing the hose and 2) the water pump seal and/or gasket died. A combination of these things led to no coolant/water getting to the engine, thus a super-fast boiling/dry overheating of the engine.
Known damage:
Failed water pump.
Suspected damage:
Leakey head gasket and likely damage to the heads. Hopefully no bore damage.
Inlet manifod is off and I'll soon have photos up of the inlets, and will post pics once the engine is out and heads are off.
Still looking at options, will likely replace whole engine.
Thinking about replaceing with an ej25 if i can't find a good ej22.
Will keep everyone posted!
Cheers,
Owen.
