Boys, I need some help. While I was about to bolt the new gasket in, I !@#$#@#@!@#$ the first screw on torque.
WHAT torque do the bolts on valve cover gasket needs to be? I read somewhere 7ft-pound and I was bolting it to to 7, but cracked/ripped the nut from engine assembly (don't you laugh at it ). Much to my luck, that screw on the engine is not part of the engine (now I will have to ask the $stealer for replacement and car is going to be out of action for few days). So please help with torque values.
Also, while I was changing the gasket (still am with the car in garage and engine open with missing bolt), I checked the spark plugs and they are NGK. I have attached picture of contact points. Do you think I should change it?
