Maybe you could use same system than me.
Oil flows to oil separator, but never back to engine. So its closed system, and pressure in motor will push gasses there, dont fear. And in top of separator there is pipe and air filter to keep gas flowing. Really much like the oil separator systems sold in market. |

Like a catch can, only problem is you have to drain it all the time... With the drain its self contained and I don't have to screw with it.

In any case the truth is that the oil is not going to actually hurt anything whichever place it goes -- just it will create a big mess if you put it in your intake, especially if you have an intercooler too. The oil separator system prevents that. I'm sure the only reason no cars come with it from the factory is just because of the added complication and expense. Plenty of big trucks come with them. It is an excellent way of dealing with oil vapor, especially on older engines that may produce a fair amount of it. Eli, since your D24T is in a 240, you might have a nice option for a place to drain back to the sump -- just put it in the hole for one of your two dipsticks.

I too wouldn't take any stock in the the opinion that its going to be full of gunk. The blowby is comming from the valve cover to begin with, which is inside the engine already. You just returning back to where it came from. I think George is right, people that are saying that are confused with the EGR soot/sludge found in a TDI for example. Sorry but EGR just does not belong in a diesel engine!

Thanks guys, you have calmed my worries on this issue. Just in time too, I was about to buy a conventional catch can.
now I will build something like this for my car. As for training it back into the second dipstick tube. Jason said he had problems with crank case pressure not letting it drain down. I might give it a shot, but I would like to develop something that sits on the valve cover and baffles it as it comes out. We'll see what happens. |

Ya it needs to drain back into the oil pan. If you drain it into the block above the oil level, you have blowby pressure in the block that trys to come up the tube and hinders the drain back. I ended up dumping into where the useless oil level sender was.
