Crankcase pressure

[Rawze]

When i build an ISX with someone here at the house, i get all the air out of the fuel system, i make sure there is no air left in the oil system. and that it has good pressure, no leaks, etc.etc. --> Then I slam the accel pedal all the way to the floor, let it rev all the way,.. then back it off only very so slightly so the rpm is only about 5-10 or so rpm less than its governed max,... and leave it there, not moving the fuel pedal at all for about 8 - 10 minutes. Scares the hell out of the truck owner. lol

While holding the rpm at a just a hare under its max, not moving the fuel pedal at all, ... if the engine starts slowing down at all then I know there is excess friction in it and it needs to be shut down because something is wrong internally. -- If it holds steady just under max rpm (just shy of the speed governor) without moving the pedal at all, then there is nothing to fear.

After that, I drive the piss out of it around the neighborhood for a bit, then straight to somewhere to change the oil again., Back home, then re-run the valve adjustment a second time.

that is how i do it anyways,,. call me crazy lol.
