Didn't read well enough. My bad.

Still possible to be firing on the wrong stroke or at the wrong time.

 

When answering most of the questions on this post I missed this one (What did you use to hold the harmonic balancer when torqueing the crank bolt to 217 ft-lbs? Any chance the rubber layer in the harmonic balancer separated?) I used a piece of hardwood and two long steel bolts stuck through the hardwood in to the harmonic blancer bolt holes. It went well and did not seem to slip. I had to put some real weight on the torque wrench to reach the 217 ft-lbs of torque. Rubber layer in the harmonic balancer? I did not notice a rubber layer? If I look from the front of the harmonic balancer can I see the rubber layer? What dose the rubber layer do? I'll see if I can get a picture and post it.

 

It good that you used a holder.
You cannot see the rubber layer....it's internal to the harmonic balancer and is what holds the two pulleys together.

 

After trying to start the engine the first time (waiting about 20 minutes looking for the problem) the engine started at a faster (still struggling) rpm an a big cloud of white smoke came out the tail pipe. As the engine did all the smoke the engine sound and felt out of balance (out of time)? It was very scary!

 

I am so excited, the auto code reader came in the mail today. It was easy to use and to no surprise it gave me the code of P0340 Camshaft Position Sensor at Circuit Bank 1 or Single Sensor. The surprise is the part (at Circuit Bank one or Single Sensor)? It almost sounds like some is not connected? I replaced the camshaft sensor when it did not start the first time? The old camshaft sensor ohmed out as good? What does the camshaft sensor read on the camshaft fly wheel? I guess I'll need to start looking at the camshaft flywheel & sensor right after I find out what or where the camshaft circuit bank is. Any thoughts you might have would be appreciated.

 

Are you sure it was not P0340 for the code?

Per the FSM for code P0340 [emphasis added]:
"The camshaft position sensor, which detects the crankshaft angle signal (G signal), has been installed on the front of right bank cylinder head. The timing rotor has been integrated with the right bank camshaft timing
pulley. When the camshafts rotate, the protrusion on the timing rotor and the air gap on the pick up coil change, causing fluctuations, in the magnetic field and generating an electromotive force in the pick up coil.

The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34 signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G signals
and the actual crankshaft angle and the engine speed by the NE signals."

Double check the connection for the camshaft and crankshaft sensors.
Is it still true that you did not have the cam pulleys off while doing your work? If you removed them, remember, Toyota uses right and left as if you are sitting in the driver seat so the cam pulley with the "R" is on the passenger side and the "L" is on the driver side.

 

The P0340 code is tricky in that the title is Camshaft Position Sensor Circuit, but see the second paragraph about the NE signal plate that is mounted on the crankshaft? Those 34 teeth are what you see in the right hand picture of your post #5 above and as where I was leading in post #8 above.

 

Sorry, Your right the code was (P0340 Camshaft Position Sensor at Circuit Bank 1 or Single Sensor). If I understand you here I should check the sensor connections and if they look OK I should check the teeth on the crankshaft sensor as I did not remove either of the camshaft pulleys. I should look for broken teeth on the crankshaft gear? I'll take pictures too. Thanks so much for your help as it is much appreciated!

 

Correct ^^^^

A broken or bent tooth will cause the issue. Those teeth are quite fragile.

 

Wow, you were right on! A tooth was bent and a tooth was missing on the Crankshaft Gear. I thought I was so careful? It must have been when I was trying to get the crankshaft bolt lose the first go around. The crankshaft pulley holder I purchased from Amazon did not fit. I finally went to a piece of hardwood and that works great! I am ording a new Crankshaft Gear & a new Crankshaft Bolt (this would be the forth time for this bolt). They are coming ground so it might be a week or so. I can't wait to hear her (engine) run! I will keep you informed on my progress. Thank you so much for helping me as you knowledge and kindness is much appreciated.

 

I tried to send a picture but the picture will not load on YotaTech.

 

Parts arriving soon?

 

Yes, The parts are here and I will check to make sure that they are the same as the old parts. Work has picked up again and the weather is bad (cold & wet) so I'm not sure when I'll be working on the truck. Lots of family here to from FL. Nice to see them. I still can't load a picture on here yet?

 

Hmm, don't know on the photo thing, but you did get pictures attached back in post 5 and 6. It seems photobucket is recommended around here as a pic hosting site....there is a thread that tell how to link in the pics from photobucket.

I've got this thread bookmarked so I'll keep a eye on it.

 

I think the pictures were to large? I resized the pictures, hope that works.

 

Yup, definitely a missing tooth there.....

 

I went down to the barn and checked the new parts (new Crankshaft Gear & Crankshaft Bolt) against the old parts and they wear almost exactly the same. The washer on the crank shaft bolt was a different shape but the same thickness & diameter. It was such a nice warm afternoon I went ahead and installed the trimming belt all the way to the bottom trimming belt cover and ended the afternoon by turning the crank shaft twice to make sure that the belt was on right and the marks (all four) lined up after each rotation.
On Tuesday I borrowed a snap-on torque wrench from work and that night tightened the crankshaft bolt to a whooping 217 ft. lb..
On Saturday afternoon I went down to the barn and finished the job including the anti freeze. I was just praying that the motor would start. Turned the key and wow the motor started right up! Oops, new problem! There is a knocking clanking sound? Sounds like a bad bearing on the a/c belt tightening pulley. Before I could get down to confirm that was the sound was the a/c belt tightening pulley it stopped (lasted about two minutes). After about two more minutes it started again and lasted about 30 seconds. We have not heard the sound again? Just not sure what the sound was?
On the positive side the motor has not run this good since before the first trimming belt was changed. The last mechanic must have had the belt off a notch or something? Because now when you press on the gas pedal she just zooms!
Thank you so much for your help with Toyota engine it is very much appreciated! All of you are awesome and your input was so helpful in this project.
Love My Toyota!

 

Woohoo! Glad you got the timing belt/crank timing gear all squared away and are running again.

 

thanks for this thread. It has saved me some time on my project. I also damaged a tooth on the crankshaft timing gear when trying to remove the gear to install a new crankshaft oil seal. If it had not been for this thread I would have reinstalled the old gear. Seems the new part from the dealer has been superseded by a new more expensive part ($70) now. Looks exactly the same as the old part. Just wondering if toyota changes part numbers periodically just so they can charge more for the part? Also the crankshaft bolt has been replaced with a new more expensive part number over twice as expensive as the original part number and dealer is saying the new bolt must be installed with the newer replaced gear. My Haynes manual says nothing about replacing the crankshaft bolt when replacing the timing belt. Any thoughts on that? The parts guy told me torque on that bolt is 193 ft lbs. My manual says 184 ft lbs for the 1996 5vzfe tacoma 4X4.
Feedback appreciated

 

217 ft-lbs for the torque on the crank bolt. The 184-193 range was later superseded by the 217 ft-lbs. Trust me on this one.

Use a holder like in this thread to hold the harmonic balancer when torqueing the crank bolt: https://www.yotatech.com/forums/f116...l-tool-186081/
