Case breather on /6, Something else I'm going to need to understand Options

[Mark Henry]

Starting to hook this stuff up as well, Howard thanks for the adaptor tip, I'll cut one out soon and add pics to this thread.

Why not make a catch can that drains back into the case and vent directly into the hole already cut out into the K&N rainhat?
I totally hate improperly vented systems or the cheap vents like in post#13, they make one fuch of a mess in the engine bay.

As far as oil proof I'll use Parker Pushloc hose for this.

You will find that if you just put hose on it and secure it with a hose clamp it will leak and drive you crazy because when the hose clamp is tightened it will distort the pot metal spout.

Its best to machine up an aluminium extension and glue to the spout with high temp epoxy and connect the hose to that.

Cheers,

I've been working on 911s since 1973 and I've NEVER seen that happen.

You can get colored heater hose cheap on ebay. This is what I'm using engine to oil tank. Then tank into a Gatorade bottle like Andy.

Heater hose isn't rated for oil vapor, especially for heated oil vapor.

In my experience, the bottom of the catch can is usually full of oil-water mix sludge, something i would most certainly *NOT* want back in my engine.

OK, you could build it so the drain back was extended enough to trap any moisture, much like a gas tank. Clean out the can once a year.

I have been doing this for years on type one and four engines with no ill effects and I've always vented to the intake, why would a six be any different?

I know that the discussion is about where to vent the case breather to, but I've found the solution to the leaking hose... get a real case breather cover, ie. off an early aluminum 2.0L. These pop up on ebay once in a while, and mine doesn't leak at all anymore...

For starters, i have 16+ quarts of oil in my system, which means i get a LOT of moisture that boils out of the oil when the engine gets hot.
In turn, that moisture rises from the oil tank and gets trapped around the top of the filler neck and down the vent into my catch can.

I routinely have to wipe off ounces of white(ish) oil sludge from the inside of the filler neck and the same stuff collects on the bottom of the catch can.
