3100 Valve Cover Bolt Torque Rating?

Weather permitting (damn Ernesto), I will be putting on a metal valve cover & new gasket to replace the old leaky plastic one over the weekend.

 

What I need to know is... What should the 4 bolts that hold the valve cover in place be torqued to (ft/lbs)?

 

I don't recall seeing this info in my Haynes manual. If anyone could tell me how many ft/lbs the bolts should be, I would appreciate it a lot! :D

Yea I have the metal cover. I ran out of daylight yesterday, so I didn't get this done too. I didn't get outisde to start working until after 2pm yesterday because somebody got blackout the night before. :redface: I do have a new hood release and a CTS installed though. :D

 

However, I was looking at the valve cover, and I'm not sure that I can get it off without removing the upper intake manifold. The rail infront of the valve cover seems to be restrictive of that. Is there some way around taking off the upper intake manifold? If I have to take off the intake manifold, what are the torque settings in ft/lbs that the bolts should be?

nah don't worry about the coolant line. Just might have to either move the hose clamp for access or take off the hose entirely. Not a big deal. Just pull the valve cover forward to clear it, then lift out. The black bypass pipe you will have to unbolt at the front timing cover, and set aside.

What is traveling through the black bypass pipe? Liquid or gas? Especially if it's a liquid, what is the torque in ft/lbs I should be tightening the bolt holding it in place near the timing cover?

coolant, IIRC it gets torqued to 89 in/lb as well

 

When I take it off when the car is not running, am I going to have coolant pouring out of it? I only ask b/c my landlord is crazy about no spilling fluids in the parking lot, or they can fine me without notice. :rolleyes:

you may spill up to a pint or so of coolant, between what floats out the timing cover, and what's in the pipe. So yeah, put something under the car to catch it. And keep the rad cap on ;)

Gotcha. Thanks for the heads up. :thumb:
