What is the use of Camshaft timing oil control valve? Is there any problem if I use the car without working Camshaft timing oil control valve? Also I need the camshaft timing as well.

It is used in conjunction with the VVTi system, similar to the Honda variant VTEC.

They provide more power (lift and duration) at higher RPM.

I would not take the chance of not using it, since the system is designed for it and it would either set an error code or cause an oil starvation problem. Here are the camshaft timing marks. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

It dosen't use a belt but a chain. They can be a little noisy.
You can remove the camshaft cover and inspect it if you want. Inspect the teeth on the sprocket for wear and the chain it self for wear.
Since it is a chain, it is sealed and uses engine oil for lubrication.

Hi there,

Your engine (1ZZ-FE 2ZZ-GE) has a timing chain not a belt, there is no time frame on chain life.

Do you know when is it the time (mileage) for the timing belt replacement?
Do I replace a serpentine belt as well as water pump while I am at it? (They both look good, but what is the recommendation? Anything else I should know?)

Sincerely,

Yuri.

The car is equipped with a chain, not a belt. There is no scheduled time or mileage to change it.

Change the waterpump if you wish, but I would not unless you see a leak.

You should change the plugs at 100K, use only the original Denso or NGK iridium.

Yes a chain as Raz pointed out.

There is no scheduled service interval for the chain.

You can remove coils and valve cover, inspect chain for missing teeth or loose chain, but generally the chain will last the life of car.

Are you having a specific problem?

Toyota switched from belts to chains in the late 90's I believe.
The timing chain has no scheduled replacement time, so you would not need to replace it, you can take off the cam cover and inspect it if you want.

The problem you got here is you don't have a belt-what you got is a timing chain.

Three questions:

What does the average rear suspension cost to repair?

It needs a tuneup. Do I have to take this to a dealership? What cost should I expect?

The timing belt has never been replaced. Partly because the dealership told me I did not have a timing belt. Is this true?

That depends primarly on what part of the suspension is needing replaced.

You don't have to take it to a dealer if you have local repair shops that have good reputation

your vehicle uses a timing chain, not a belt. Chains are built to last the life of the engine so they do not have maintenance intervals like a belt would have.
