Recently I replaced the valve seals on my regal vin A 3.8 2 bbl as it was burning oil, 95000 miles, I doubt it's piston rings. Anyways I put the engine back together, and forgot to torque the rocker arms. I used a regular ratchet. I started the car up and it ran like s***. The sixth cylinder was backfiring up the carb everytime it was supposed to fire, although they were very tiny backfires, and you would mistake them for a tick when inside the car. A very trusted mechanic and friends theory is that I overtightened the rocker arms, and that sixth cylinder intake valve was being held open a tiny bit by the too-tight rocker arm. So his logic made sense to me and another trusted mechanic/friend, so I took of the valve covers to retighten the rocker arms with a torque wrench. I torqued them to 30 ft pounds as specified by Haynes manual, but that seemed way tighter than I had it before. Is 30 ft/lbs the correct torque spec? What might be going on here? Is my friends theory correct? I need some help on this.
