Put piston number one on its compression stroke/TDC then align the cam and crank. See below.

If you are setting timing up after doing a valve job you need the cam and crank lock tool to set up the timing or you will bend the valves again?

Yes, that is what he is trying to do. It still doing the same thing. Turning over but will not start. And he has been trying to start it. So hopefully no valves bent again. :( Do you think he bend my valves again?

Maybe. The only way to check for sure besides tearing it down is to perform a compression check. Best to recheck all the gear settings, lock them down and rotate the engine by hand a few times to make sure they are set properly. Then perform the compression test and reassemble.

Yes, because I just paid him to put the heads on, and I cannot afford to get them taken back off. He was trying to start it why it was not in timing. I was telling him I knock the car out of timing when it first back fired on me. And I think that is where he mark it. And I am thinking he does not know how to reset the timing.

He cannot get pass setting the timing. He does not know where to mark it. He tried to start it when he thought he had his marks. I do not know!

Thanks a bunch.

Okay, the image above shows the marks. But he needs the locking bar to keep the gears from turning while he installs the belt.

I agree. Whenever the variable valve timing unit hub is removed you need the cam lock tool to reinstall it since there is no guide on the cam itself. So he needs the proper tools to set the timing. I agree with rivermikerat that you should just take it to another shop that can do the job and send this guy the bill if he cannot fix it right?

Hey guys, I just wanted to give you an update on my car. Yes the mechanic bent all the valves and not to mention I only had to bent when I got the head done. Now I have a foreign mechanic fixing it and now it is at the head shop again. Thank you guys for saving me before he put another finger on it. Now he has been nowhere to be found but the police will find him. :) Thanks

Six cylinder two wheel drive automatic.

How do you set this when head and cams are replaced? What is the procedure?

First thing you need is the cam locking tool to lock cams in place. Can you get one? Let me know.

Have one, but that VVT has no return spring. Keep getting a cam advanced too far code. How do you set up this VVT with the cam and which way does it move and what is its at rest position?
