CAM Pin broke/pushed into CAM core GPI VVT
This is the latest issue on my VVT CAM install on my L99. Apparently I did not get the CAM dowel pin aligned properly with the CAM phaser/gear this damaged the dowel pin causing the cam to spin freely when I try to remove it. Has anyone ran into this issue before? I'm considering putting a couple 1/4 steel rods throught the hole just above the cam under the timing chain cover(picture attached)to hold the CAM still so I can get it off. I don't like the idea but not sure what else I can do...
Hopefully someone has ran into this before.... Sent from my SM-F916U using Tapatalk |

No, no issues here with a 2015 install.

put the pushrods and rocker arms on and snug them down. That will help hold the cam in place. THen use an impact gun to remove the cam gear/phaser bolt.

So my buddy wants to tack weld the cam dowel pin to the phaser gear. What are your thoughts on this? Said it will insure alignment and help the pin stability. What are the thoughts on this? I feel like it will be tough to get the timing chain back on.

If that was what is needed it’d come from factory like that.

How'd you figure out it was the dowel pin? If you tack weld the gear to the cam, the gear has to be perfectly perpendicular to the cam at all angles. Or else the gear could have a slight wobble that could cause engine damage when spinning at max RPM. I don't think it's a good idea to tack weld. You don't want to chance it.
Be careful when doing the dowel rod trick. I had 2 wood dowels all the way in on my L99 cam swap and 2 lifters passed the dowels and started to fall. Luckily I saved it, but remember that the dowels are not fool proof. I was using 5/16" round wood dowels.

Troubleshooting I took the cam phaser out. You can see (picture) where it either popped out of the hole on the gear or I never had it lined up correctly. Sent from my SM-F916U using Tapatalk |
