Ok I've read and watched about half a dozen blocks of instructions on how to replace the phaser in my 5.4 04 F150. I dont see where they are placing the timing block to keep the chain slack out. I went ahead and purchased both sides "phasers" where in the heck does the wedge tool go? anyone have a photo for me to look at?
Basically your just jamming the wedge down between were the chain narrows in the timing cover. all you want to do is jam the chain in such a way it wont fall down and come off the lower sprocket. If it does fall you will need to remove the front cover which actually isn't that hard, an extra hour is about all. I've had mine apart way too many times to count. Did you do an oil pressure check before starting this job? And the check done with a manual gauge, not the one on your dash?
You can go on alldata and buy the licence for all the information on your truck.
I think it's about 19.00 last time I checked, I'm a tech and alldata is what we use.
I would like to add check your oil pressure first before forking out money for parts. The 5.4 and 4.6 are known for the tensioner blowing and causing oil starvation to the top of engine. This causes the phaser problems in some cases not enough oil pressure. Not saying this is your problem but better to be safe then sorry. They are also bad for VVT screens plugging up or coming a part
