The valve stem seals on these motors harden with age, and you start seeing the classic symptoms: occasional smoke on cold startup, gradual oil consumption that gets worse over time, sometimes oily plug threads. It's not catastrophic but it's annoying and it's incredibly common on high-mileage...

Spent some time scrolling Toymods, Australian Toyota forums, NZ build threads recently. The Aussies have been putting these motors in stuff most Americans don't even know exists. RT142 Coronas. RA60 Celicas. Hilux Surfs. Old Crown wagons. Curious what the strangest, most creative 1UZ swap is...

Hard to believe this thread is 22 years old. I think this is one of the most important threads on the entire site, historically speaking, which is why I'm bumping. The MK4 Supra V8 swap was nearly mythological at the time, and turboandrew documenting the test fit in real time pulled a lot of...

Reading back through this thread is funny in hindsight. Some of the calls here aged well and some aged badly. Anaema's claim that you couldn't build a 1UZ using totally aftermarket parts was reasonable in 2006 but it's not true anymore. We have forged internals, multiple turbo manifold options...
