    For me it's rust locked, yep too much water intrusion due to faulty dried, hardened, shot head gasket. That's why always recommend to re torque all powerhead gaskets at first 5 run hours from out of the box or when installing new ones in, all gaskets will have ceded a bit due to heat, a high...
