Wire looms,PCV valve,distributor,fuel pump,exhaust manifolds,oil pressure sender,temp sender,spark plugs,harmonic balancer,and oil filter all were on the engine when it got painted.
Do not dig into it too much.The factory line way of doing things was crude and no attention to detail was paid.Besides how do you shoot a moving object with a paint gun?? very quickly and on to the next one coming down the line...
It is not uncommon to se parts of the engine with huge thick paint runs,and others have little or no paint on certain areas.
The back of the motors are unpainted and I guess they werre painted standing on their back.That may explain the paint runs going from the front to rear of my valve covers.
But I could be wrong..who knows??
Motor mounts (painted black) were added later right before installation.
