1st thing people think is thermostat but it's headgasket... pre-2000 legacy with 2.5L will always headgasket probs.

one Ottawa suby tech does JDM 2.5L swaps for about the same price as the headgasket fix price.

Like Alf said, evanG did it 3 times on his 97 legacy gt wagon but he sold it with about 420k kms....
