Possible blown head gasket

[alf]

If you go the swap route, it's gone cost you about 5K+. You need to replace

Motor
Crossmember
Clutch
Exhaust
ECU
Wiring(that's the hard part)
Fuel pump
+what ever need to be replace one you are there....

Fun to drive after....

If you have a DOHC, it's a phase1 block. Phase1 block are the problem, they were a ej22 modified block. The block isn't stable, it will blow up again. How long, no idea... 10K-60K-100K, don't know but it's probably will die after an other 60-70K.

Phase2 block swap, Evan Gablin(on of the Ottawa guys who won Targa few year ago) did it on his Legacy after 2-3 motor rebuild(ya the car has ~400K and still track it as much as he could). He seem to have some good result with that swap. He's the only person I know who has done it. His main problem was the manifold intake, it didn't fit properly. He re-drill the hole for the screw that hold the intake in place.

Thanks for replying guys, this is alot of useful info.

Joe, it is my Legacy and it has 160K on it. The 97 never gave me a problem with overheating, but I guess the Phase1 has caught up to me. Could I get a Phase2 engine and swap the heads with no problem, after planing and replacing with the STI 3 layer head gasket?

Alain, was Evan's motor a DOHC, as I was thinking of doing the same thing, maybe?
