fastener tightening specifications

I have gotten 3 emails saying i have new answers but i see none.

Yeah, there is a strange glitch in the system. I'm going to try again with different pictures.

Okay, thank you. Means a lot.

I tried a few more times and it refuses to post the information. Wipes out even plain text for some reason.

So I'll wait for it?

I'm trying to get it to post. There is something wrong, not sure if it's the post, pictures or what at the moment, but I'll keep trying. The front cover sealant is sensor safe rtv.

applied as in image Spot 1 is a 5mm bead, 2 is a 5mm bead, 3 is a 14 mm dab.

The cover torque is a sequence. These are new bolts for 1 through 3
1 and 3 first pass to 11lb ft. final pass of 130 degrees
4 to 15 all to 18ft.lb
16 to 19 are 89 inch pounds
number 20 is 18 ft.lb.

That what you were looking for?

Yes sir and cam sprocket bolts and valve cover but you have done a lot already.

Cam cover - 89 inch pounds.
Cam actuator bolt - 22ft lb plus 100 degrees.
Do you have the special tool to lock the cam in? EN 50793

No. looking it up trying to understand it. guessing I need this?

Is it necessary or a way to lock actuators otherwise?

Also on the intake side with the plate on it doesn't have the notch to sit it.

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.

Thank you.

Surprise tool number 2. any other ones I should be aware of?

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.

Thank you. yes, very strange system but we get it now.

Probably would have cost them a whole 30 cents to have a notch on both sides to make it easier. At the moment it's fun to even get parts being the UAW is on strike again, GM may not exist much longer.
Anyway, keep us informed and ask if you need anything else I think the posting issue has been cured.

Torque on harmonic balancer is only thing else I can't find. Otherwise everything you helped me with was awesome.

Using a new bolt torque to 111 ft.lb. then add 140 degrees.
