Timing belt broke on shut down - 1999 100 series

[NC LX]

Update
I received a video with the truck running.
When the belt broke, it destroyed the crank position sensor. A new sensor was installed a few days ago and that is when there was zero compression on all cylinders. The new sensor from Toyota was actually bad. A new crank position sensor was put in today and it fired up and sounds ok on the video. Compression on bank 1 was 170-170-170-150 and on bank two 170-170-170-150.

I am hoping everything is ok.

Persistence and ih8mud family paid off.

Thank you for all the assistance!

Awesome to hear everything is ok.
I’m still wondering and I’ve never gotten a straight answer. Is the 4.7 interference or not? Appears from your situation it’s not.

My unofficial understanding from the 100-series forum is that the VVTI motors are and the non-VVTI are not. A few folks have torn town the non-vvti motors and confirmed that at least they are not interference motors.

This is my understanding also. It has more to do with the vvti setup or not.

Yup, that'll mess up your crank sensor.

Great to know! I have an interference Tundra with a timing belt at 119K miles. I have the kit to replace my timing belt but only my driveway to do the work.

I've also got birf soup, a leaky power steering res, and a soft brake pedal on the Land Cruiser.

I know I'm a bit late to the party, but it's really suspicious that they came up with zero compression. That's a mechanical test, a crank sensor wouldn't cause that.

Glad to hear it's fixed and not ruined though!

I would guess they are pulling the compression numbers through the toyota techstream system.

Learned a lot. Can discuss offline anytime. She is so excited it is fixed. Never wheeled and drives better than most new stuff. Crazy.
