Crankcase ventilation.

I am trying to find all the crank case ventilation lines on my ALH and I have checked the ccv puck on the valve cover but and wondering what else I need to check to diagnose high crankcase pressure. ( My main seal is a little leaky and I was to make sure it's the seal and not high crankcase pressure.

thanks

That's it on the ALH.

The vacuum pump blows into the valve cover but it doesn't move enough air to cause high case pressure.

Define "high crankcase pressure". The breather scavenges as the air flow increases.

I think whatever method you are using, you'll find is perfectly normal on any healthy ALH. If the crankcase pressure was excessive, you'd see the dipstick pushed out of its tube.
