Hello guys, I recently replaced my cam phasers to get rid of the knocking noise on my 2008 ford f250 5.4L with 150k miles, when I removed the passengers side phaser the small pin in the sprocket in the back was broken.
When I was ready to install the new phasers I encounter one little problem, the small pin in the sprocket in the back of the phasers was not aligning perfectly with the hole in the camshaft and I had to move the new phasers one teeth down of my markings ( moving the timing ) to get the pin align with the hole in the camshaft. This was done on both sides.

Now with the new phasers, truck starts, drives but kinda of rough, a little stalling and trows p0345, p0349 codes. Also after 10 mins of driving it gives me the low oil pressure warning light (after truck its warm/hot), but it goes off and on.

My question is, do you think timing is the issue? and if so, can I go back and try to move the phasers back to original timing?, or any other ideas would be appreciated. Thanks

 

Sounds like timing is off ----was the camshaft in the neutral position and did you wedge-lock the chain when you removed the phaser?

 

Yes camshatft was in the neutral position and time chain was wedge-locked with the small cheese piece. The only thing I did was to skip one teeth on both sides to be able to insert the pin in the back of the phasers so it could align with the hole in the shaft.
I think is timing too, do you think I can just go back and try to move the phasers to the original marking ( I know i just have to move one teeth up)? thanks

 

If you installed the phasers off one tooth that is your issue right there. Go back and set them where they should be.

 

Im doing it this week, and I will keep you guys updated with the final result. Also I bought the oil pressurre sensor/switch but I have not been able to find it under the truck, I looked all over the internet for a diagram, does anybody knows where this switch/.sensor is? thanks

 

Driver side of the engine. Just behind and below the lower radiator hose connection.

 

Found it, thanks. I have decided to do the entire timing (chains, tensioners,etc) do I need to flush the radiator? how hard is this procedure, I have found several videos online and I think I can do it. I know I have to remove the valve covers , tensioners, radiator etc. Any tips, resources haighly appreciated, thanks.
