I am aware of the oil consumption problem. I change the oil every 5,000 miles. In between oil changes I'd have to add about 1 - 1 1/2 qts. I wasn't aware of the VVTi and head bolt problems. It is good weather today but with work and my daughter Dr. appt I'm not sure I'll be able to mess with it. The winter storm is going to hit tonight. I probably won't be able to mess with it for several days. But if I'm stuck at home it'll drive me nuts if I don't set up a tent and mess with it.
I need to research the VVTi and read through the info you pointed me to via pm. My wife is wanting to get another car. I'm trying to explain it's cheaper to fix this one even if it needs a motor. Rather than buy some random used car. I hate buying used vehicles I know nothing about. People are good at covering up problems in used cars.
If there is any other info you happen to think of or run across, feel free to let me know. I'm all ears on it.
This is the 1st time I've went to a forum for help. I'm surprised at the help that's been provided. I really appreciate it. Thank you.

 

ask as many questions as you need till you have the answers on this problem



if it helps any
closest i can find
the electrical-wiring-routing-of-toyota-camry-2AZ-fe - engine bay




you are not here yet but
If your wife wins on buying another vehicle ...suggest a toyota camry ...you know more about them these days

 

I was able to get back out there today. Enough snow finally melted and it was warm enough.
I started by checking the compression of each cylinder. From left to right- 1. 45PSI 2. 30PSI 3. 25PSI 4. 28PSI. That's very low obviously. I then put a 12in long 1/4in extension in each plug hole and turns the belt by hand. All cylinders where moving. I don't think all the rings would go bad at once without any warning. All the spark plugs looked good also. All that leads me to the valves and the VVTI crap. Which I don't know much about. Am I on the right line of thinking?

 

wait for toyomoho responses on those readings

1. 45PSI 2. 30PSI 3. 25PSI 4. 28PSI.
should be in the 100s I thought.....thats the dry reading

to confirm it isnt the rings do a wet reading

squirt some oil into the each of the cylinders re do compression test ... if the numbers stay the same ...... its all valves

 

Yea, the compression should be around 200psi I think. I will try to get to the wet test today or this weekend.

 

Minimum compression is 142 psi. The engine will run OK with less but not your readings.

Reference the post about checking valve clearance. Make sure the intake cam timing is not off due to VVTi assy issues. On the compression stoke all valves on the cylinder should be closed.

 

Will do. Not exactly sure when I'll be able to have time to. I will post the results when I get it done though. Thank you again for the suggestions and direction to go. If it is the VVTI, what does that consist of? What sensors help control it? If you know. I'm curious.

 

try this .............VVT means variable valve timing

if this round unit is sludged up with old oil..or is sticking ...the valve timing will be out each revolution

 

That actually tells me a lot. I haven't been able to do anything else yet due to rain and trying to work. Everyday I'm home and could work on it, it is raining. My kind of luck. It's suppose to be clear this weekend. I'm going to mess with it then. Weather permitting.

 

Thanks for posting back.
