jmars and others- I tried that PCV install you suggested on that oil loss thread and by golly, I've got one speedy wagon now! I posted to that other thread but i didn't want it to get buried. I'll keep an eye on the dipstick and let you know how to oil consumption goes. Thanks
p.s. Everybody search Mar. 10 "excessive oil consumption..." for the full story...fascinating stuff.

There is an intersting article at http://www.stealth316.com/2-krankvents.htm .

Is the Deutsch valve designed for turbos? ET Performance and Racing, makes high performance oneS designed for turbos. In their FAQ they say the regular ones don't last long.

I took a look at the article. Looks like the PCV system on the engine described works a little differently than the one on our turbo red blocks: with those, air from the intake is actually routed into the crank case, which would make constant vacuum even more essential.

The concern in our case is just to keep pressurized air (under boost conditions) from travelling out the manifold nipple, up the skinny vac line, through the Y-fitting, into the oil separator and thence the crank case. One element in the discussion is the fact that 240 Turbos don't even have the skinny vac line... a one-way valve in the line is sort of compromise between that setup, and unrestricted, 2-way flow.

I have no idea of the intended application of the Deutsch valve... probably not for a turbo car. I plan on inspecting it on a regular basis, but I'd love to find a proven component (that doesn't cost $75+) to use. The Deutsch valve (at least the one I got) does not completely restrict flow in the "wrong" direction, but limits it pretty well compared to flow in the "right" direction.

I'm glad to see there are a bunch of people thinking about this & experimenting...

Hey, good to hear. I also put the PCV valve suggested bt JMARS - Deutsch #161 - in the small vac line from the breather Y-fitting to the manifold.

I don't have a great baseline for oil consumption, because I've been dealing with leaks for a while, but I think I've got things sealed up & I'll see how things go. I do seem to have slightly better boost performance in heavy-throttle situations :> ... boost performance was already pretty good (g-valve).

I, as a number of people, are following this information- What turbo owner wouldn't like to reduce oil consumption?

Do you have a part manufacturer and number you can share. How did it fit and if you had to build it up how did you do that? Thanks for any additional information.
