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!

@barnfind9141972 i found the images of 1.8 twin carb factory euro spec engines.
one from 74 euro 914, other from 74 euro vw 412. i lied. or am half mistaken. the crankcase breather line comes in right above the filter. technically though it is after the filter so the vapours are in the airstream being drawn to carbs rather than perhaps dousing the filter or going through filter. you can also see that its not a straight breather even with the carbs - the breather is a pcv with a valve operated by intake vac from one of the carbs. i think that stops situations where you get a lot of oil sucked up out of the engine or drawn up out of engine. can't remember exactly how these things really work. i think it is that intake vac situations close the valve. but i am probably wrong.   |

A very German approach where I’d like to take an American approach haha, as simple as possible |
