Hi All,
I'm in the process of finishing up a Weber DCOE install on my 79 SA. While I haven't road tested it, the car seems to be revving very nicely in the garage.
I had the Holley set up for the last 1000 miles. On that set up, the oil filler neck breather was hooked up to the base of the air cleaner. There was no PCV valve.
I'm wondering what I need to do with the Weber DCOE. It seems to be running fine with the breather hose not hooked up. Can I just put a crankcase vent filter on the end of the hose and not hook it up to a vacuum source?
This is a car that gets ow mileage like 1000-2000/year.

Yes that the way old cars ran for decades

I thought so but I wanted sanity checking! My Formula Mazda 13B just has a tube heading toward the ground.

you should have some sort of filter or catch can on it though, you don't really want it sucking up dirt. a catch can will also have the benefit of catching oil instead of undercoating your car with it and possibly damaging suspension rubber.

If you hook it to vacuum use a pcv valve do you don't have a large leak. Best is to run it into the air filter so when running it sucks the oily fumes back in the intake.
