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!

Simple way is as the factory did it, most the 1.7 oil towers have a breather where the PCV valve is located, cut a hole in one of the air cleaners braze in a small piece of pipe you can connect a hose from the breather. 1.8 oil tower has a pipe where the hole for the PCV valve goes, omits the valve.

valve/flame arrestor is inbuilt into the oil cap itself for 1.8 L jet! (IMG:style_emoticons/default/beerchug.gif)
same as D Jet but different.

nice thing about the EFI cars is the oil vapour is fed in after the air cleaner filter saving that from getting doused. won't solve OP's concern as its hard to dump into a carby car without going in before the filter.

EDIT - i think VW managed to do it on the twin carby versions of 1.8 engine but its not individual air cleaners. they had that single air filter box with the flat ducts heading off either side to the twin carbs. the crank case vent line fed in on one of those ducts i think after the filter. you kind of need one of those style air cleaners which were really only around for the factory twin carb engines with pathetic solex carbs.

@wonkipop the OEM did it right with FI and the way it breathed but if I did it with carbs it would dump into the filter and eventually deep into the carbs and make a mess correct?

yeah i was just editing my post above having remembered that the carb aircleaner follows the same principle as EFI which has the feed duct down to the throttle body.
you got a better brain than me.

i think @bbrock (? think i got the right forum member there) built himself a homage aircleaner for much bigger carbs like OP has.
its in his restoration build thread. he did a real nice job making that aircleaner himself.
