out of the driver valve cover there is a steady flow of blow by or something. when the oil fill cap is takin off, once again there is a steady flow of gas no where near the flow of the driver side. i know that people put a hose to redirect the driver side to the rear of the truck. but the whole thing in the nutshell ... is this blow by or gas normal for a 7.3, i know its a stupid question but i was just wondering... the truck now has 329xxx on the clock and runs extremely strong. so its making think that it is normal but kinda concerns me a little... so help.. :)

if you take the cap from the oil fill, turn it upside dowm and place it over the tube. If it blows off it has exessive blowby. They all have some.

If you are in doubt do a comp test.
