Center section of manifold cracking..

Bumping the post yet again. So it cracked the 2nd aftermarket manifold. Noticed white smoke on start up and when it first gets going and an occasional haze prior to and after overhaul. At this point we're strongly suspecting an injector is running afowl in a loaded condition, while passing a leak down test with 500 psi loss in a minute. EGTs 1075 at its highest since removing the radiator shrouds.
