I am having problems finding any answers to this specific engine on the internet. My car listed above has a turbo automatic 6 speed transmission. My vacuum pump on the end of my exhaust camshaft froze or broke and ended up binding up and bending the exhaust camshaft. Beyond finding parts because of GM strike I cannot find out what kind of sealant to use on the side plate going back on and I need to know to torque on such plate the cam bolts and arms on the cam as well as the valve cover bolts. And anything else I would need to know or should know putting everything back together from the timing chain to complete install that normally would be missed.

Its vvt actuator on intake cam as well, as per illustration tool can only be used on exhaust cam actuator. So how would the vvt actuator be held on intake side?

You are supposed to have the timing chain on and set the timing and then use a tool EN-50656 to lock the chain, then the other tool locks the exhaust side.

So you torque the intake cam before you put cover on. In trying to understand when to torque the intake cam actuator cause of the vvt on both intake and exhaust.

It's a strange system, but you place the intake cam into the exhaust cam position, then install the locking tool, and install the actuator and bolt and torque it down. Now remove the locking tool and lift and roll the intake cam under the timing chain across the head into it's correct position and as close as possible to it's timing marks. Now you can put the exhaust camshaft into place and install it's actuator and time both cams to the correct spot. You need the locking tool to hold things in place as you torque the bolts. The timing chain lock is normally used when you are taking the cams out, it holds the chain up and keeps it from releasing the tensioner.
