Need Second Opinon
Hey guys i will do an intro later tonight. I hafta go to work.
so im working on a 2003 chevy impala. 3.4 179xxx? miles. Just did the lower and upper intake gaskets. It runs smooth at idle, but under acceleration IN PARK, there is a tapping noise. seems to come from the front of the engine, but i cant tell which side. It does not do this when in gear under load. I checked the rocker arms at 2,4, and 6, because it was easiest. does this sound like a rocker arm?
thanks in advance.
