4.7L 2UZ-FE Valve Cover Gasket Job

[eliesh]

Great video but.... Depending on where your hundy lived it's life (read northeast) will play a big part as to whether the valve cover bolts come out easily or they break. There is a lot of "broken valve cover bolt(s)" content on this forum including from me. There is also OTRAMM video where he breaks several of the bolts on a hundy valve cover - so even the most highly skilled LC specialists are not immune. I honestly believe there is nothing that can be done to prevent these bolts from breaking-if they are gonna break... One broken bolt, let alone multiple, takes this job sideways quickly. Just issuing fair warning...

This problem with these valve cover bolts breaking is an issue I've never heard of with different Toyota/Lexus models. Is it because the end of the bolts extend past the head and are exposed for corrosion to form and cause issues with the bolts?

I think it's a combination of factors including the "throughbolt" ends are exposed and they are directly over the manifolds (per @OTRAMM) . I also understand that the steel bolt can fuse with the aluminum head via a chemical process - though im not a chemist/metalurgist. Anyway great video. I'm just envious that you made it look so easy - like you've done it all your life or something. I on the other hand work at a desk for 30+years so i got lucky that I was able to drill and retap the 6 bolts I broke...

A video is never a true account of how hard a job actually is. If our videos were the length a job actually took, our videos would all be a minimum of 5 hours long. This was my first time doing a valve cover gasket job on the 2UZ-FE engine, but I've done many valve cover gasket jobs on other models, so I'm not foreign to it.

I'm always shocked how much shorter the videos end up being after I trim out most of the struggle and the time spent looking for the tool I just set down I used one of your videos while looking for an easier way to get a 100 Series AC compressor out. Thanks!!
