It looks like the engine is on the stand , so tilting it horizontal as I stated above would be the best.as the compound is vacuumed in you should see a pattern of the crack slowly sinking into the cracked area, that indicates it is working and allows you to see what portion is being treated, remember to smear a little over the area after the vac. is removed and make sure it does not keep seeping in during the cure time as to avoid a pin hole in the crack surface. I had it seep overnight and had to redo a small area, that was a large cracked though.
