I would LOVE to see a how to in this forum. I've done cam swaps on pushrod engines...but never on the new OHC 4.6 .
DSPE, was the cam swap easier than a pushrod?
yea LOTS!! here is a quick list of the install procedure.... gets as much of the wireing harness as loose as possible, and get as much of it as you can pulled out of the way so yo ucan remove the vavle covers, remove the valve covers,
1.make a small mark on each timing chain and sprocket so you keep keep an eye on it so it wont jump time( more than likely its not going to)
2. make a small wedge to put down in the tming chain to wedge it in place, u can use a friend to hold up on the cam phaser and keep tension on it.
3.break loose the cam phaser bolt
4. remove all the cam caps and bolts
3. with the caps off now wedge the chain or get a friend to hold up on the phaser and remove the phaser bolt
4. remove cam
5. put on new cam and caps dont tighten
6. put the cam phaser bolt back in and snug up on the cam( the phaser will only go on one way it has a dial pin to line it up on the cam)
7. check your timing marks make sure they still line up
8. tighten up the caps on the cams and torque to spec
9. torque the cam phaser bolt
10. repeat on other side
11. CHECK THE TIMEING MARKS AGAIN !!!!!!!!! MAKE SURE ITS STILL IN TIME AND HASNT JUMPD
12. reinstall valve covers
13. plug up your wires
thats pretty much it, springs and retainers is a different story, it takes forever. you air up each cylinder and change the springs one at a time!
I think its easy i know i could have some changed in 2 hours pretty easy with an extra set of hands to hold the cam phaser when i need them too!
When i get a little more time i have pleny of pics, im going to use to get a good write up on it with lots of detail.. Ive just been very busy and havent gotten around to it.
