i have a noise coming from the passenger side head. i pulled the valve cover to check the springs and nothing is broken. any suggestions before i put it back together would be tremendous. i did however notice that the number four cylinder had a loose rocker arm that may have been the problem but will not know until i get it back together. all the pushrods are as straight as an arrow. also what is the torque specifications on the rockers. thank you very much!!!

 

Apply Loctite to all the rocker bolts and reinstall all the rockers. Torque the rockers to 22lb/ft, rotate the crankshaft 180 degrees and double check the torque on all the rocker arm bolts.
