i just received the krank vents and wanted to make sure i installed it right. both arrows from the krank vents are facing opposite way from
valve cover is this right?

there is a lot of air pressure inside the engine, like when i try to open the oil cap.
is this normal?

 

no you should have vacumn

 

yeah with mine if you pull the dipstick while its running it will suck it back down.

 

Yeah, arrows point away from the valve cover. There should be a suction noise when you pull the dipstick.
