Remove the bolts on the cam pullies. On the VVTi cam, make sure you put some rags under to catch the oil or else it's going to go everywhere and leak on the timing belt. Then also remove the valve covers. Also, you should be able to slide of the timing belt.
Most of the important stuff is stripped off here.
Remove the VVTi solenoid oil line. Keep in mind, put a rag under that to catch oil as well. It shoots out a good bit. Another tip, use a screwdriver or something to pry the camshaft out. It's going to want to stay wedged in there and you're going to have to work it a little bit to remove it.
What you've all been waiting for. What do the BC cams look like? They look stock lol. Keep in mind my engine is a GTE so there's that weird looking pattern on the exhaust camshaft near the front.
Close up to know it's legit lol.
Put all the stuff back in and double check the clearances with a feeler gauge and reshim if necessary. You should know how to do this if you're attempting something like this.
If I remember right, the clearance specs are:
Intake .15-.25mm, Exhaust .25-.35mm
Once clearance is checked, put on the pullies and recheck timing to make sure it's spot on.
Button everything up and you're ready to roll.
