I never heard the air box drains called slobber tubes except on these bus boards took me awhile to figure out what they were talking about lol it doesn't bother me any longer I have enough trouble trying to figure out what some are calling other parts on the engines you know like a supercharger for one   

good luck

What are "slobber tubes"?  I can't find that term in my Detroit manual.  Perhaps you are talking about "air box drains"?

I guess I am. Truckers call them "slobber tubes".

I don't think 'truckers' run 6V92's anymore, and I find the term offensive.  If you are blowing oil out your air box drains your engine needs an overhaul.  Catch containers only delay the overhaul.

I cannot believe you found the term "offensive". And I also learned the term when I was driving truck out of Dallas, TX.

I can assure you, no offense is intended. Maybe we should just refer to them as "The S word".

When I bought my first truck in 1980, the 8V-92TA had the air box drain tubes plumbed into the crankcase.  This was great except if the aftercooler started leaking coolant.  Detroit shortly afterwards came out with a bulletin to cut the tubes, crimp the lower portion and just let the airbox drains (what you all are calling slobber tubes) drain to highway.

In recent years, the EPA has started to count the engine blow by as part of the engines overall smog count.  So now, all engines have some sort of coalescing filter that takes the blow by mist, condenses the oil, filters it and returns it to the oil pan, but still allows the pressure in the crankcase to be relieved.

There are coalescing crankcase filters made for all engines-albeit they are expensive (around $1,500).  And specially for 2 strokers are a collecting dual inlet tank to attach to the air box drains that can be periodically drained.  Good Luck, TomC
