Ok, so you offer some electronic services. Do you make any custom specialized devices? Like say speedo converters, speed/rev limit cutters, or something for engine integration into newer cars with plenty of computers?
Your 1uz vvti clean looks misleaded me into thinking you fully rebuild them prior to installing ) I never dig into them either, source engines from Jap wreckers. They mostly come with some 60.000 km on them, but no one is remotely as clean as yours. I noticed that despite of low mileage all of them have low oil pressure (below 3bar @ 4000 RPM) and heavy carbon buildup (sometimes even stuck rings, though chemistry usually fixes that), even those looking fresh and clean. That's quite contrary to the 3UZ described in this thread - it's USDM, has over 300.000 *miles* on it, and only needed stem seals replacement.
