Engine rebuild or engine change? big dilemma.... - Toyota Yaris Forums

you don't want 2zz or 1zz injectors unless you are running forced induction or you are converting to E85. they will flood the engine with fuel. to check pistons for wetness you'd pull out a spark plug and shine a light into the hole. maybe need to rotate crank to bring piston closer to the hole. you could also pull the intake manifold and inspect the valves through the ports for bleed-by. if leaking the valves will be all brown and oily. a 1zzfe out of a scionXD/corolla will prob go for the same price as a 1nzfe. maybe $100 more....
