I would NOT recommend stuffing steel wool in the blowby tube, which would cause pressure to be put on turbo, resulting in premature turbo failure. This motor need's to breathe.

Thanks. I did see that this blow by tube is connected straight to a port on the head. This blow by tube is a straight forward tube with no separator. So it looks like that one I posted is somewhat of an aftermarket addition.------- but at this point I think I got to much oil in the system. I was not dropping the oil out the blow by until after the oil change, My oil way way over full on my dipstick at cold temp, and now two days laters it's still just a little over full. It seems to me that the system is just purging out the excessive oil. I was thinking about using a siphon pump and getting the levels back to where it should be.

And maybe adding some of the gear oil too

Excess oil in any engine that is high enough to get to the bottom of the rods is very bad. It causes a lot of oil "fog" and oil out of the blow-by tube but that is the least of the problems it causes. It also foams up the oil in the pan and causes aeration.

Aeration can cause pre-mature/excess wear in the entire engine and can also cause one to spin a bearing easily. It is as bad as having coolant in the oil.


Just thought i would throw that out there.
