I rebuilt my 340 over the spring with a valve job, Voodoo cam and some head work. I installed some TTI's and drove it to the shop to have them weld my X pipe and Spintechs in. Obviously it was loud as all get out on the way over with open headers, but ran like a champ with no problems. After the exhaust was on I hear the dreaded light dinging noise. It originally was not very loud and sounded like a loose rocker arm. I only live a few miles away so I start to drive it. A mile down the road I lose power and dinging is much louder. I pull the valve cover off and had 1 rocker arm still attatched
The two outer shaft mounting bolts were laying on the edge of the head. They had apparently vibrated loose. It doesn't appear to be anything major, a slightly bent rod. I am a little confused. I torqued the shafts down to 17 ft/lbs. Do I need to use some blue Loctite next time?
