Hello I have had my 04 4runner for almost a year now, and have almost 204000 miles on her and am wondering if there are any full rebuild kits for the v6 yet? Anyone rebuild this engine yet? Thanks in advance
 
Haven't called toyota, I don't think it needs one, but I plan on rebuilding my fj62, so I figured I could rebuild them at the same time
 
I doubt there are a lot of kits. The 5vz has such a low probability of mechanical failures that there simply isn't a market for rebuilding them. And there are so many out there that have outlived the vehicle they came in, even if your 5vz wore out before the vehicle, it would be easier and cheaper to put a takeout engine in as a replacement. I personally have never been pleased with rebuilt engines. I don't believe it is possible to rebuild a modern engine better than a low mile factory assembled one.

That's my take on why you're unlikely to find a total rebuild kit. There's just no market for it.
 
ya there is a rebuild kit, I think it is listed as a overhaul kit. we haven't had to a full rebuild on any at work, but have done a hand full of head gaskets. the head gaskets are few and far betweet and not a common failure. if you wanted a compleat built motor try jarco, its expensive but a quality motor. http://www.jarcoinc.com/
 
Call LOWE or American Toyota, I bet they have a rebuild kit, or they can put one together for you. To the idea a rebuilt motor can't be as good as a factory one, I would suggest you just need to use the right parts. I would suggest that if you used good quality OEM or better parts and had a good shop do the work, there is no reason why it couldn't be just as good or better.

Just my opinion.
 
I have a 95 taco with 216,000 miles on it and its still got it! The only thing it needs is manifold gaskets. I'd say drive it till it quits then rebuild it

X2. When you put in inferior parts, then yes a rebuild will never be the same. But if using OEM parts then you can be sure that it's just as good when it left the factory.

How this chain of logical events has gotten skewered is beyond me. I blame the internet...
 
You should do a compression check on the cylinders first and then if the compression is not up to par then start thinking about rebuilding.
 
My take on rebuilding is that unless you have equipment that is on par with that used by Toyota, it's unlikely that you will have a final product that is comparable. The tolerances on a typical machine shop mill are not as good as one at a billion dollar facility. Does that matter? Absolutely. How much? I can't say. All I can really confirm is that I've not found rebuilt engines to be equal to factory ones in my experience with rebuilds. How many engine shops will have 99.99+% of their crank shaft seals last 200k miles? I'm guessing not many.
