Show me your breather box

[effvee]

Good morning, if you stay stock, your stock parts work fine. But if you go up in bore, stroke, and compression you are going to start seeing leaks; probably first around the crank. Not sure if you are talking type one, if you are, normally the type one does not have a crank seal.

For me getting the blow-by addressed from different locations aid in total size. That blow-by gasses can be hot, without the aluminum steel wool,, the hot oil vapors can get out causing a mess at wherever the blow-by container is located.

Why the valve covers, its just another place that can be tapped without drilling into your case.

My car, a 2332 type one, I had not added valve cover vents, just the stock location.
My car did leak from the crank, due to new cylinders, not yet mated rings, higher compression. If you choose venting to the carb (carbs), which one? Or are you going to "t" the two? Not venting will cause a mess.

If I can use -8 in several locations all the better.
