AOS Failure: what breaks first?

[maytag]

Well, I tried a couple of versions of a catch can, and so far I'm not happy with any. There's not enough space in there for anything of any real volume.
I've seen a couple of installations where they plumbed the catch can to the trunk, but this being a street car, I didn't want to get that crazy.

So....

I put in a loop of clear, wire reinforced hose. Hopefully this will allow me to see what's going on, and hopefully there's enough volume in that loop to catch the oil, instead of making smoke bombs. And I can just remove it and drain it, until I come up with a better plan.

So, how did that work out? Tell us! :dance:

So far so good. No more smoke bombs. I've had to drain it after each track-day, and yes, it always has some accumulated oil in it, which would presumably have otherwise been in the intake.

Brilliant, I might copy this!
Did anyone actually put a catch can in the trunk, connected between AOS & plenum inlet? Any reason that wouldnt work?

A lot have done that... and it's been covered on this forum... so you'll find good information if you go that route.

It would seem Maytag did his research on the cannisters... and if you considering going the trunk route, it'd be his brain you'd want to pick.

He's not little brains.

Hahaha. That's perfect.

The catch can is ideal, but it has to go in the trunk, and I'm still trying to pretend this is a street car.

When you do it, don't just vent it to atmosphere. You need that vacuum on it, so route it back to the plenum.

Dismiss all of those guys who will tell you that the volume of the AOS is important: it's not. Vacuum is vacuum. The wc is important, the cc isn't.

I wonder if you can fit the 987 intake system on the 986,.that AOS system has a return tube back to the AOS ,.??
