Ok thank you for the picture.The engine I bought does not have the factory breather.It has a tube with what looks like a kn type breather so I ll have to figure something out. I don t want a bunch of oi mist all over
Hows it going? Read this article and decided to do this setup. I did make some changes and i have a strange issue. Rather than running the PCV line and Valve cover line into the catch can, I drilled valve cover (off the car of course) and tapped it to use a barb fitting, ran the hose toward the vam and mounted on the firewall with an air filter. Deleted the Pcv valve and ran that line over the valve cover into the catch can which is mounted next to said filter. I read that there should be steam coming out, which it does, but it smells like gasoline. I checked it every week and sure enough it seemed like there is gas in there. Oil has been changed since install and there is not gas in the oil. I have however forgotten to check the catch can lately and today sure enough that s.o.b was filled to the brim with gas. Searched turbotbird and turboford with nothing coming up so i figured I would ask here since this is where i originally got the idea. On a lighter note, the blow by is gone!
How are you determining it's gas? Is it clear like gas or is it oily?
Gas will vaporize out of the oil once the engine reaches operating temp so the best explanation I have is that there IS gas in the oil and it is getting to the catch can where it stays below cool while the gas in the oil vaporizes away.
Where did you tap the valve cover? The stock location has an internal baffle so that's the best place, others will introduce excessive oil into the catch can (or in your case, into the VAM).
Shortly after posting i asked my father-in law the same questions. Pretty much asked me the same question as to how i determined it was gas. I assumed it was gas due to the smell. I then performed a redneck test on the liquid pulled out. I soaked a paper towel and tried to light it on fire. It did not burn. After which we determined that its moisture build up mixed with oil. Also determined that I should continue to drain it weekly. The valve cover is tapped in the stock location and there is little to no oil making its was up the line with none reaching the filter. Is there anything else i should do to the setup or do you think I'm good?

I am also having this issue with my motor will be looking to do this soon, would the blow by also cause it to leak out of the oil pan from random spots? I replaced the oil pan gasket with a felpro. Is there any tips you recommend when doing the oil pan gasket, maybe I missed something?
It can make it leak oil from various spots if the crankcase pressure is high enough. Once you remove the pressure, it shouldn't leak anymore unless it pushed the gasket out where you can see the problem.
I typically glue the gasket to the pan and let it set up partially before installing so it will hold in place.
Stinger I somewhat copied your system and am having issues. I made my own catch can out of two in pipe with a filter on top and drain in bottom. I have a similar fitting(smaller only 5/8 to crankcase and 3/8 to valve cover) and I'm using the stock separators without the pcv. And my catch can has no baffle. The problem I'm having is that it seems to be pressurizing the valve cover. You can lift the separator on the vc up and feel air pushing out from the separator at idle. And it's blowing blue smoke out the exhaust. It seems to get better as it warms up and is the worst at a cold idle. Do I not need a check valve in the valve cover line to keep it from pressurizing the head? Or are my parts just too small and insufficient?
