Hi I was changing the timing belt on my 04 v8 and the cam shifted.
I moved it back but am not sure if it was back to where it was.
was wondering does anyone know what is the margin of error on the timing to where the engine can compensate?
I turned the engine by hand and hear clicking noise and can't tell weather it is made by the timing chain inside the engine.
Any suggestions?

Mate there is no margin for error.
It must be exactly as it is supposed to be.
You did not have the locking tools?

no I did not. My friend worked on one before and told me I didn't really need one.

I turned the car over to test it and heard cluncking noise and turned it off imediatley.

it sounded like a disel engine.

Have I messed up?
How can I realign the cams?

 

[pkravtsov]

I aligned the crank to the notch on the plastic covers and took off the covers and noticed that the cam that slipped inperfectly level but the passenger side cam appears to be off by one tooth.

Is it damage done or can I salvage the situation by realigning the cams by purchasing the tool t40005?

BTW im really stressing right now!!!!
Any help would be GREATLY appreciated.

Very sorry to be doom and gloom but most likely if you heard clunking and it sounded like a diesel I would think that was your valves hitting the pistons. Recorrect the timing and do a compression test that will tell you if/which cylinders have an issue.

How do I do a compression test?

Drag said it.

I didn't want to be the first bearer of bad news, but chances are that you have some very expensive damage there.

I would think a tooth out shouldn't be terminal.
Realign the cams and see how you go.

+2...I would recommend getting someone who knows 4.2s and timing chains to do this...

before you screw up anything else, tow it to a mechanic.

If you are not comfortable with doing a compression check, you will definitely not be comfortable with resetting the cam timing on the engine.

good luck!

In addition, since you have the front end off, I would also recommend changing the water pump as well

 

[pkravtsov]

I hope you are right. I ordered the tool t40005 and t40009. They should arrive with in the week. After I will realign the cams. I'll share the results... I HOPE THERE IS NO DAMAGE!!!! Wish me luck!!! Lol

I changed the pump and thermostat and 3 pullies. Thermostat was the reason for this undertaking. The belt are changed as well....
