Looking for some guidance on my front crankshaft seal. I currently have motor out of truck and figured I’d replace the front seal. I forgot to take a photo of how the backside of pulley sat prior to removing. With the new seal in and the pulley mounted and torqued, I have about an 1/8 to 3/16 inch reveal between the plastic dust cover and the face of the block. Should it sit flush against the block, or is this correct?
