According to my Chilton's you are suppose to remove the exhaust rocker from the #1 cylinder and both intake rockers on #4 cylinder with the keyway on the crankshaft at 12 o'clock position. this should be just past TDC on cylinder #1.(passenger side head )
for the other side (drivers side ) rotate engine 180 degrees or the keyway at the 6 o'clock position remove the intake rockers from cylinder #5 and exhaust rocker from cylinder #8.
This is to prevent valve to piston contact
Yeah, but I think that's only required if you're removing the camshaft itself, which it sounds like you don't have to do if you're just replacing the phaser. Can anyone clarify the procedure? I'm going under the assumption that you:
1) pull the valve cover
2) align the engine to TDC (for the passenger side head, or another value for the driver's side)
3) shove the timing wedge in
4) mark the timing chain link, phaser, and camshaft in relation to each other
5) remove the phaser bolt and remove the phaser
6) transfer the mark to the new one
7) install the new one in the same orientation as the old one
8) install the new bolt, torque to 30ftlbs, add a 90* turn
9) pull the timing wedge
10) install valve cover
Also, I heard somewhere that you have to discharge the AC and remove/move the condenser to get clearance for the passenger side valve cover to come off. Any clarification on that?
I just had mine done at the dealership.....that cured the ticking noise. When the engine was apart the dealer took me over by the machanic and showed me this phazer thing. From what I could see, you don't have to remove the cam, you need that tool to hold the timing chain in place. the machanic made it sound easy with the right tools. I hope this helps...I really just wanted to know what the hell this thing does and will I need to replace it again in another 40k.
Just got done talking with a friend of mine who's a Ford master tech who's done a bunch of these. He says:
Pop the valve cover
Mark everything (chain, phaser, camshaft)
Throw vice grips on the camshaft so you've got something to hold the cam in place with when you unbolt the phaser from it (to keep it from drastically shifting, and to help you line it back up when you bolt the new phaser in place)
Shove the timing wedge in good
Pull bolt and remove the phaser
Transfer mark to new phaser, bolt it up, torque specs, yadda yadda
No need to pull lash adjusters, line the motor up, pull the cam, or anything, "simply as hell".
He says I "might" be able to move enough stuff around on the passenger side to get the valve cover off, but if not, then I'm going to have to discharge the AC.
I'll try to take some good pics while doing this and make a good DIY writeup.
