You can make on alot cheaper.
I got a water separator from Sears but had to return it as it was rated at 100f at 175psi.
I think the plastic reservoir will melt.
High temp plastic of glass would be the best.

I saw one of these in an 80 about 3 weeks ago. Aside from the ARB non-winch bar, this was the only other mod he had done. His had a high heat plastic resevoir -- set up looked very similar to the one shown. Don't recall the manufacturer of his. He seemed interested in a bit of wheeling, so I gave him my business card and asked him to call or email, but I haven't heard from him yet.
He tried explaining the benefits, but I'm still a bit lost -- what's the main benefit of this for the 80?

That's a lot of dough for a crappy little separator.
But I would think that if you had problems with oil getting into your TB, the right thing to do would be to fix the problem rather than just capture the oil. This is not a fix.

Well, I think rebuilding the motor would fix the problem but I am not going to rebuild the motor just to stop the oil sucking

Well...you could rebuild the engine. But maybe it's just a simple as a new PCV valve Perhaps a plugged port or leaking hose. There are a lot more possibilities that I'd look at before I rebuilt the engine though.

Yes, that's sorta what I was wondering. On my rig, I have a good PCV valve yet when recently removing the air intake hoses that go from the air filter area to the turbo intake impeller, I saw some slight residue of motor oil inside the inside of the hoses. This oil was more or less clean and clear and super dry probably from all that air rushing past it. It easily cleaned up completely but after that my throttle response was remarkably improved. That got me to thinking about this oil catch contraption and also why my motor is blowing by this oil any at all; the compression on all six cylinders is awesome, the leakdown test on all six cylinders was awesome, it runs awesome, no fouling of plugs, no missing, no hesitating, the temp holds perfectly perfect at all times, no decreased economy, no smoke from exhaust, absolutely no indication of any problem any at all. It might be a function of the turbo, or not, but since I'm not needing to rebuild, I guess I gotta look at reducing the blow by by whatever factor I can. Any other thoughts? Thanks.
You got oil in the other (#2) pcv hose?
The one that doesn't have the pcv valve.

Yes, some slight amount that over time worked its way into the intake hoses. I do not know if this is typical with turbos or not??? There was not enough oil anywhere to really restrict the airflow at all, I think simply having the super smooth surface on the inside of the intake hoses helped airflow as opposed to the inside of the hoses having a sticky surface of dry oil. I'm totally guessing here in case that is not evident!!! Keep in mind that the #2 hose is connected with a metal sleave and metal tube directly to the intake air hoses which run from the air filter area directly to the turbo intake area, I imagine there is a tremendous amount of suction created in those hoses as the turbo's intake impeller is super-sucking air through the system. Again, totally guessing. Anyway, I really have no oil consumption to speak of (approx .5 liter per 3000 miles and I do have a super small slight leak from the oil pan gasket so that accounts for part of the .5 liters) so this PCV blow by is not much but if I can catch that much, however much that is, then I can perhaps prevent crap from getting into those hoses??? Maybe I should try to post a pic so people can see where this hose connects? Thanks folks.
I have enough suction from #2 to suck a cup of liquid (SeaFoam) in no time flat at idle.
landtoy80 said:
Right, but what I am trying to think through is that your suction goes from the open end of the hose to the valve cover right? My suction goes from the valve cover to the intake hoses as a result of the force of the turbo intake. Again, guessing but this basically explains any oil in the intake hoses right? Tell me if my wonderings are wrong cause I really dont know, but I really want to!!! Thanks.
My suction if from the valve cover to the throttle body.
If I pull #2 hose from the valve cover, the motor run rough and I have vacuum that is commong from the throttle body.

Here, let me show the setup here...hope this works...sorry for the dirt and dust; I'm sorta sloppy this week!

I was in Wal-Mart tonight the same separator, identical except for painted blue was $11, I don’t think the hose, bracket and PLASTIC hose barbs are worth $50, quite a rip-off,
The waly world one was rated for 125*f had warning specifically about not to be used with synthetic oil, it looked cheesy, especially the guide vane that imparts the swirl, I am going to go to Pep-boys and see if I can find the Amflo version,

I think this:
Looks an awful lot like the stuff on the far right
The first pic is the backside of my throttle plate after 110K miles (I assume no one has cleaned it before) , the second pic is the front of my valve cover you can see the clean spot where the timing chain throws oil on the cover, forward of that not much oil flows and oil vapor / blowby / mist condenses on the relatively cooler surface of the valve cover, the front of my throttle plate looked just fine with only some light carbon around the edges
So this funk is being made in the intake, not coming in from the high pressure side of the Throttle plate, my engine does not backfire so that leaves EGR and PCV as possibly sources, EGR alone would make a sooty powdery deposit, not this tar-like gunk,
I am not sure how harmful this funk is in the intake but could cause deposits on the intake valves and seats reducing power and eventually causing problems later in life

My #2 hose (the one without PCV valve) was cracked, replaced both hoses, PCV valve and grommet, I still get oil in the #1 hose (the one with the PCV valve)
There will always be some blow-by also some oil evaporates at operating temp, I think some oil in the #1 PCV hose can be expected how much depends, I still do not know what to think of LT’s oil in the #2 hose except his has a lot more miles than most of our cruisers, and perhaps more blow by at higher power that the #1 hose can take care of?
Turbo cruiser, how are the PCV lines routed when you add the turbo? I take it the #2 hose is the one that goes to the intake duct, is the #1 hose still routed to the intake?
RavenTai said:
Correct! In the pic the #2 hose that connects to that coupler goes under the intake hose to the valve cover. AFAIK the #1 hose (w/ PCV valve) is unchanged from stock setup. Thanks for that post man, that was cool.
Ok then when the intake manifold pressure gets abvove the pressure of the engine (during boost) flow in the #1 hose reverses (intake manifold has higher pressure than the engine) the check vavle function of the PCV kicks in and the valve closes, and now the only outlet for the gasses in the engine is the #2 hose
Hey TURBO clean that engine man your slipping you big 
. Otherwise your not gonna be allowed to play with the people.

I think the truly cool people have the dirtiest dustiest engines, just ask Junk!!!
Hi folks, some additional advice if you please...can you take a look at this setup and tell me what you think...it seems especially appropriate as it is all metal and has a high flow rate. I was worried about using anything with plastic since the separator will likely be located close to my exhaust manifold. Thanks I appreciate any advice.
