PRIME WITHOUT THE INTAKE MANIFOLD ON
I prime all of my engines with the intake manifold off, valley open. You can see oil escaping around lifters and cam bearings. You can see if you have the wrong base circle camshaft on SB Ford hydraulic roller cams and if the lifter bands are poking out of the block. You can see rotating lifters or if they are sticking. This has saved me several times, saved many cams, saved lots of hours in dyno time and removing and reinstalling manifolds and in comebacks.
