I find that I can buy a JDM engine for about what I will have to pay to get my valves set. A Toyota stealership is the only place I can find that will even set the valves. I've nearly begged for help on that issue but nobody has responded...

It would seem that the age of these vehicles would preclude the concept of JDM - a vehicle in Japan being, in our perception, prematurely retired and parted out. Yet there are engines for sale.

Any thoughts on this matter?

Why do you need to mess with your valves? 300K is walk in the park for these motors with mere simple tuneup maintenance stuff.
 
I haven't adjusted valves since the 1990s on 1980s 22r engines and the last time I did it I didn't have to adjust much.



So like Dogtail asked. Why are you wanting to adjust them?

We dont have a screw driver and nut adjustment anymore like the early 80s 22R did. It all has to be done by shims.

This would be an extremely time consuming process to complete. I can see anyone that would do it have to charge significantly to complete the task.

Also, the participation on this forum is extremely high on all threads. Sometimes nobody has came across a particular issue or nobody does it in the parameters you set.

So stating you begged for help and nobody responded on 1 of your many threads that lots of users contributed on isnt very accurate.

You specifically asked if anyone did it a mile parameter that you selected and the answer was no because nobody activity involved on this forum responded. ;)


Easy wild tiger. We all try through our own experiences to help others on their 3rd gen repairs and maintenance. :D

What I find amazing is the volume of threads you start. You'll start a thread for diagnosis help, then you'll start another thread for the repair, then it seems like there's another thread for results. I usually avoid clicking on any thread you start now, but today is slow so here I am to complain.
 
The 5VZ-FE engines aren't known to need regular valve adjustment checks like the 3RZ-FE requires. But, if you wanted to know how to do it, we have a video of doing it on a 3RZ motor which would be the same technique as the 5VZ. You just have more valves to check on the 5VZ. To get to the point of having the valve covers off, you can use our valve cover gasket video.

This is a time consuming and tedious job, and like you found out, a dealership with their high labor rates will rape you on this. So, I suggest you take up wrenching or forget about it altogether because any shop is going to charge you quite a bit to do this. You may as well buy all the necessary parts to do the valve cover gasket job because it's all the same labor to get in there.

The passenger side you can check with minimal work to gain access. And depending what you find you can use it to help you make a decision.

There is a tool (I have one and have used it 3 times now) that will allow you to remove the shims without removing cams.

3 engines and I only ever had to adjust the exhaust cams.

I have never adjusted the valves on a Toyota direct-actuation (cam on shim/bucket) engine, ever. That includes about 1 million total miles over multiple vehicles that I have been 'in charge' of...

Unless you are building an engine (err, heads), it just shouldn't need to be done. Easy enough to check clearances with a feeler gauge while doing valve cover gaskets though... Changing the shims is a different story.

[MENTION=148218]JZiggy[/MENTION] and others that have checked valve lash on their 3RZ motors have noticed the need to make adjustments. I'm guessing the Toyota engines you've owned weren't prone to needing an adjustment.

Yeah. 3s-fe, 3s-gte, 5vz-fe, and I suppose you could count the 1gr-fe in my dad's 4th gen...

I know a guy who replaced a transmission and front differential in a Suzuki Vitara because he didn't realize what manual locking hubs are.
 
I've done 4 valve adjustments on multiple vehicles with both the 3VZ-E and 5VZ-FE engines. The process is the same. My local dealership flat out refuses to do a valve adjustment because it can quickly become an extremely frustrating job if you are not able to remove the intake camshafts (like when doing a timing belt job at the same time, for example).

Unless you have a supply of shims on hand, you'll be special ordering the shims from Toyota for the exact size needed. They come in 0.05 steps in size from about 2.50 mm to 3.25 mm. It's an extremely precise job that involves a lot of patience. It would be simpler than an engine swap though, but not a JDM swap. You have to strip a JDM down to a dressed long block, remove parts off your engine, put them on the JDM engine and then put it in. Took me about 2 months of work.

That's a lot of work for an engine that actually runs ok.
 
OK well if you would rather read about some cubic-dollar "build" there's lots of that...

I'm no rich guy with a mud toy. I came in here looking for people experienced with getting these things going.

My valves are noisy - REAL noisy. Why else would anyone want to set them?

How much are valve shims? $8.22 Really. And there are 24 of them...

I don't want to bother anyone and/or get into any pissing matches. IF you please?

I am aware that toyota engines, as a rule, never need the valves adjusted. I wonder why mine does? Maybe poor oiling to the top end? Maybe low oil pressure?

It seems this motor does not have the type of oil pressure sender that will provide a PSI reading. One might assume. If it did those scan tools would display the oil pressure...

I perceive my posts as legitimate attempts to get the info I need. If you are (somehow) offended by them, please ignore them and have a wonderful life :)

Dude, you need to relax and take a chill pill. If this is not your only vehicle, you can get the valve covers off, find out which valves need adjusting and then just buy the shims you need. I highly doubt your going to have to buy 24 shims.

Why do you need to remove the intake cams, and not the exhaust cams?

What parts need to be transferred? Throttle body? Sensors?

Everybody swore up and down this truck was bullet-proof and would last forever... I'm starting to regret buying it. Just today another problem surfaced. I'll have to start yet another thread...
 
Doesn't your truck have 300k+? If you expect to have to do nothing to a truck that's covered that much ground over almost 20 years you're a fool.
