Help with some torque settings please
The FSM is a wonderful book but sometimes finding a specific item can be a pain.
91 L98. What is the torque setting for the 4 long bolts that hold the throttle body to the plenum? I am guessing 25 ft lbs as that is the setting for the runner bolts.
And I cannot figure out what line plugs into the smsll vacuum port that jutd out under the throttle body. It points straight down.
The 91 book lists no section for servicing the brakes. It refers me back to the 1990 book. Grrrrrr!
What are the torque settings for all the brake system bolts please? I am replacing the rubber lines and the discs/pads.

[EDIT] See post #4 for a better and more complete answer.
On my car that line goes to the EGR solenoid and nowhere else. The vacuum to the canister comes from the intake manifold and also goes to the PCV valve.

*That is from text of the FSM but if you check the torque specs at the end of FSM sections it mentions 15 N-m / 11ft-lb

Ron, it looks like that hose goes to the canister up front and to the egr solenoid.. This is where the one on my 89 goes also..As for the 4 bolts on the Throttle body, I just tighten them up till there tight and have never had a problem. I only worry about torque settings on the important stuff like intake manifold , heads and brakes..I know alot of guys torque everything, but my way works for me...Having said that , I just sent you a PM with a list of the specs for a 91 Corvette brake system...
