Default 5VZFE question

I would talk to Jim's Got Parts for a good deal or Central Foreign Auto for a good lower mileage long block. I paid 1200 5 years ago for a 90,000 mile motor that's still running a blower @ 10psi. Don't be discouraged, there are thousands of happy 3.4 owners for every mishap like yours. This kind of thing happens. Keep us posted on progress and let me know if you need help and I'll do what I can.

If it's any consolation my 2000 4Runners have 240k and 300k. Both 5VZFE motors are tighter than the 1FZFE in my 80 with 290k.

so.....

ALL the valves are still in their normal locations?

like it really did break a rod and it wasn't a valve that got munched due to botched timing belt/tensioner breaking a rod?

5vz is non interference. It won't munch the valves if you screw up the belt, it'll just run like crap.

Major bummer about the broken rod. Should be able to find another motor on short order. Where does your dad live?

Thanks the tips and consolation guys.

He's in Detroit. Sounds like he found a 98,000 replacement and they're going to swap it in and do the timing belt, waterpump, some gaskets, etc. I told him to get under that thing and get a good look at the rod. I want to know where and how it broke. There was no indication on the top side looking into the cylinder with a camera that there was damage, so that's why they pulled the pan, apparently.

The shop is recommending the replacement engine rather than just a new rod because they think there might be fragments throughout. Sounds plausible?

Isaac already mentioned that it's a non-interference motor but I was more wondering if the engine happened to maybe have any head gasket work or something. A broken rod is unheard-of even for supercharged 5VZs and crazy for a stock engine. Maybe it threw a rod and something was lost in translation. That can happen (right Ige?).

The best way I can think to break a rod is to get oil, coolant or water in the combustion chamber. Maybe HG? Is it running Toyota red coolant or does it have something else? I have a theory that Toyota coolant reduces HG erosion but worse is mixing coolants.

I would go with a decent used engine instead of just replacing the rod in situ. That worked in the 2F but modern engines are such close tolerances and designed with a lot less margin. When the rod broke who knows how badly the crank or cylinder walls were damaged. At least my luck wouldn't be in favor of tempting Murphy.

What the heck are you going there for Marco? I didn't think there were any businesses left to bring anyone there for work.

Good guess actually. That's where the family business has been since the 60's.


Seriously though, he has the Runner at a shop in Pontiac, which is about 30 minutes from downtown D-Town.

Sucks about your Dad's 4Runner, Martin. A friend of mine is from Detroit, with roots in the auto business. She's not allowed to even consider owning anything other than American. Hopefully your dad will give it another go. Sounds like a freak occurrence.

Your post had me dig up the history of the VZ engines. Fascinating... http://en.wikipedia.org/wiki/Toyota_VZ_engine

p.s. check your pm's when you have a minute.
