Here I go again asking stupid questions, but my Dad said stupid questions didn't get asked.
On my 8V71, the slobber tubes extend down to about 1-2 inches below the seam of the block and oil pan. I want to install a "catch tank" for them. I think that I know that these are mostly "gravity flow" tubes, and don't have a lot of pressure behind them. Therefore, to run them any way except straight down would not clear the "slobber" out of the heads and would cause other problems, right? If in fact that is the case, how do you route these to a catch tank? In looking, it appears the only place that I could reasonably mount a tank would be on the frame right above where the passenger side muffler is. Is there another place that you guys have put yours? If so, how and where did you attach it? How did you route the slobber tube to it? And finally, I have seen on previous posts that the tank could be made of PVC pipe and inlets/outlets. Does anyone have a picture, diagram, etc to show how these are constructed, or at least some instructions on how they are built?
By the way guys, I got the oil changed out to Straight 40W (Delo 100). Will take first trip out in it this weekend. Will let you all know if consumption/slobber is reduced and how it performs. Am really anxious to see.
Thanks for all your help. |

the catch can does not have to be fancy,have seen a one gallon milk jug wired to each one.as long as you have 7 gallons of oil in it,things will be LOTS cleaner |

Buddy, the factory unit attaches to the pan bolts. Everything from the block to the end of the tubes is replaced.
The factory says to route the hoses so that they run downhill all the way into the tank. The outlet from the block should have a valve installed to limit the airflow through the tank.
These are called check valves, but that is not what they are. Airbox pressure is applied to the top of the valves. When the engine is idling, there is not enough pressure to cause the valves to close. When the engine speeds up, the airbox pressure rises and closes the valves.
This means that they pass oil only when idling.
For what it's worth.

Over my head, not really. The way you wrote that statement could lead someone new to think you meant the catch can has to hold 7 gallons.
I have worked on these engines way to long to know you meant 7 gallons of oil in the engine.
The engine will still produce "slober" even with the proper oil level. The main stuff that produces "slober" is worn engine parts, mostly bad oil control rings. Another main producer is over fueling and excessive idling. Wrong viscosity of oil doesn't help.
