Yes correct.

I wonder if this individual has ever considered packaging the mod into a kit that he/she could sell to DIYers?

Silk

He has his own shop, specialises in M96/97 engine . He has considered it but you know how it goes with liability, bad installation and possible unfair bad publicity. I understand his point of view completely.

For those having issues finding the Stelan thread...

STELAN Aftermarket AOS

I understand his view completely, the 996 market is such a niche and fickle market that it doesn't make sense, let alone the liability. FSI and L&N have managed to successfully do it, but have had to go through hell and high water. An AOS redesign also has the burden of the EPA to be a "monkey on the back"..You have to take your knowledge from this thread and DIY (take your own responsibility) or leave it alone and OEM (and take your chances)..IMHO

Silk

I can ask if he wants to make some kits and ship it to you overseas. No idea about pricing. He uses a modified catch can. And makes his own mounts. This extra labour and steps adds up to price. So I would not be surprised it will cost double the amount of the parts only. Without the catch tank it is plain simple.

I'm still on the fence as to putting a catch can between my new AOS (next week) or just leaving it stock. All my driving is short distance daily commuting...

I’m wondering if any of these mods has a chance of passing emissions testing, for those of us living in areas where it is required. In my area it is an annual inspection, and the first step is a visual check that all emissions components are in place. Even if there is no CEL illuminated, the capped off plenum hose is a dead giveaway that the system has been altered. Maybe a rookie inspector wouldn’t notice, but any visual check by a knowledgeable one would discover it.

If the mod affects the fuel trim you'll probably get a CEL anyway.
The BMW X5 'catch can' looks stock and is so slender it is less likely to be noticed.
Maybe do the cheapest/simplest/least conspicuous version of the mod and check fuel trims with a scanner/Durametric. The mod would be easily reversible. assuming this is an addition to the AOS and not a replacement.
The really compelling application is that your AOS fails and you want a temporary fix until you have time to replace the defective AOS. If that is feasible w/o fuel trim issues it would help some folks?

808Bill

Easy enough to put back for inspections if needed. I don't need the inspection here.

JTT

Yeah, I get it. Shame though

What's tied into the AOS tube to the intake manifold?

Scott at Team Harco

That's a fuel vapor vent line (I assume from the charcoal canister). There's a thread (that you have visited) that describes this stuff....

808Bill

Yes, but I can't remember it and have been driving to work (6 mile each way) with it all disconnected (waiting on my AOS)...I've been overloaded with info these past two weeks (with the flu)

Am I causing more damage?

Scott at Team Harco

I get the overloaded thing. Sometimes life just keeps pouring it on. Hope you're feeling better and get some time to relax....

I doubt you are causing damage. And by this, I mean the car and the environment. You will be releasing small amounts of fuel vapor and crankcase vapors into the air. If you can't get your new AOS installed soon, you may want to try something similar to my temporary fix (125,000 mile thread). Don't sweat the little things.
