I’m starting this thread to document my 2nd gen Tundra 2UZ-FE VVT-i rebuild.
This is more of a personal journey than a formal how-to. I’m not a professional engine builder, and I’m not trying to present this as the definitive way to rebuild one of these engines. I just wanted one place to document what I find, partly because it has been hard to find easily digestible rebuild content for this engine online.
I also figured posting here gives me a little bit of insurance by taking advantage of this group’s combined knowledge. I’d love to hear advice, corrections, and criticism as I go. If you see something I’m missing or doing wrong, please call it out.
The truck is a 2007 Toyota Tundra with the 4.7L 2UZ-FE VVT-i. I bought it last year with about 270k miles and a known major oil leak from basically everywhere. The original plan was to pull the engine, reseal it, clean everything up, and put it back together. Once I opened it up, that plan changed quite a bit.
The leaks had gone unaddressed for a long time, and once I got into the engine I found signs of debris-related wear inside the system. So instead of the relatively simple overhaul I was wanting to do, I ended up breaking down the short block and rebuilding junkyard heads in lieu of reusing my original ones.
I know the common advice with these engines is usually "just swap in a good used 2UZ." That probably would have been the easier route, and maybe even the smarter route depending on how this goes. But I felt like I was up for the challenge, and figured this knowledge would do me well for long term maintenance practice.
My next post will be of engine initial state for reference of what I'm working with.
Stay tuned!
