I'm just trying to get a clear cut answer regarding this engine. Any info would be greatly appreciated!

i'm confused... u said u contacted several mechanics who said it's non-interference, but u take it to the one mechanic who says it is?

have u asked him exactly what is damaged in the engine to require it's replacement? has he even opened it up yet?

it was also my understanding that the sc400 was non-interference, but u say this mechanic had a manual that states it is interference... now i'm lost too!

was the 1z motor even available in japan for the sc/soarer? i thought the biggest baddest engine they had overseas was that twin-turbo inline-6.

If the belt is already broken, you can check the clearance by turning the crank with a wrench. No need to ask around, just check it and that's that. Turn the cam a couple notches too if you are in doubt.

The older models should be ok.
