Crankcase Breather Recommendation Options

[barnfind9141972]

Hi everyone, I went for a spirited drive last night and came back with a huge oily mess all over the engine. I have dual carbs and no crankcase breather as I wasn’t aware the need of one, what do you all recommend? I have a 1.7 block and heads that are now a 2056 and would like to put one in that is as simple as possible. Hoping something that just connects to the oil fill tower. Thanks!

I bought that catch can from some online retailer. My thinking was that if I vent into the atmosphere there would be no vacuum pressure in the engine. Smelly engine vapor was non existent. The idea of the can is that you catch oil condensation. In reality though, gravity just put the oil back into the filler, never a drop of oil in the can. The heads and the top of the engine (oil tower) all vent via the can. I ran a line to the rain drain hole because it doesn’t rain on 914’s in California.

@mtndawg gotcha, yeah the oil condensation is what I want to catch to keep it off the engine itself. After driving the car hard have you ever noticed oil coming out of the hose you have venting out under the car?
