Sea#3 is the winner: Although all injectors were soaked in cleaner for a couple of hours, and all o-rings replaced with new, the #1 injector failed and allowed raw fuel to collect in the cylinder. Since this is a Horizontal config cylinder, the fuel did not drain down the side of cylinder walls, instead it sat there waiting for the unsuspecting piston to be smashed to bits. The compressability of a liquid (gasoline in this case) is practically non exisitent, and therefore, as Sea#3 said, the engine "hydraulic locked" itself into oblivion. Now at least I have an excuse to bore the engine .020 in order to get rid of the damage to the #1 cylinder walls. Thanks for the responses, Skytow

Just finished my rebuild on an EJ22 engine with a Topline Master Rebuild Kit. Aligned all timing marks as per Factory Manual, and spun engine on bench by hand several times to make sure nothing binds and all goes smooth. Drop engine in car, hook up electrical, and one last time spin engine by hand to make sure everything is OK. Since I was missing an exhaust gasket at the Y pipe, I momentarily cranked engine to see if it would start. Engine started on one turn, and idled perfectly. I closed the hood and called it a day. Next day, I picked up gasket, finished installing exhaust system, and proceeded to start engine again, This time engine started with a bad miss, and then suddenly seized. I was amazed. Car ran fine yesterday, and seized today after 20 sec. of running Confirmed engine siezed by trying to spin by hand. What I found. Engine Oil was completely dilluted by gasoline. Both heads were fine and unnaffected. #1 Piston smashed, connecting rod bent, No damage to bearings, crank, or valves, cylinder #1 slightly scored. Who can quess what happend?

Anyone have suggestions on engine kits out there for a EJ22 engine, non turbo. I have a 96 Impreza, four door, and I would love to turn it into a sleeper. What options do I have to upgrade to a 2.5L engine? Would it mate up to my existing tranny, engine mounts, exhaust? thanks
