So after a recent blown upper radiator hose and overheating the previously slow coolant loss has developed into blown head gasket(s).
Pumps compression into coolant even when cranking. No water in oil, knocks etc.
Car has 206,000km and full service history, MY06 Liberty 3.0R Auto.
Have two options:
1. Drop into Subaru mechanic and let them disassemble diagnose and repair (have not contacted yet to discuss, have to wait until Monday).
2. Replace engine entirely with lower mileage warrantied unit.
Risk with option 1 is how much work is involved, are heads cracked etc, is engine garbage/toast.
Risk with option 2 is replacement engine is no good.
From what I can tell from my research is Option 1 could be from $2k to $3k+ depending on engine damage. Option 2 would be about $3200 inc GST and [robably faster turn-around.
has anyone had any experience with HG on these engines, costs? and other possible hidden traps? do they warp/crack heads etc.
many thanks.
