Oil Catch Can on A3

[SoFresh]

Just curious if anyone on here as added an oil catch can on their 8P yet? If so, where exactly did you guys tap into? I know BSH was coming out with a kit for our A3s and Eurojet produced one awhile back however I never received one from them, nor has it been released.

If so, post pics and where you tapped into at. Thanks!

pros and cons?


first time hearing of this

really? I've done these on previous cars, had the PERRIN catch can on my old Stage III WRX, here is the info stolen from PERRIN's website, didn't feel like typing it out:

OIL CATCH CAN
Blow-by is a constant problem with any turbocharged engine. While a normal byproduct of the combustion process if it isn’t contained outside the engine it will collect and gum up the valve train, turbo and most importantly the intercooler and plumbing. When this occurs it reduces the thermal efficiency of the intercooler, thus losing power and performance. With our cleverly designed and easy to install silicone catch can you can control this problem. Available in red, blue or black to compliment any engine bay. Universally designed to work with all turbocharged applications.

COOLANT OVERFLOW TANK
Replace your ugly OEM coolant overflow tank with a PERRIN catch can /coolant over flow tank. The PERRIN Catch Can doubles as a coolant overflow tank that can change the appearance of your engine bay. Included with the kit are numerous mounting brackets that allow you to install the tank virtually anywhere. This can also add clearance to aftermarket intercooler piping, on kits that don’t include them. The sight tube on the side shows how much coolant is in the overflow tank. Available in red, blue or black to compliment any engine bay. Universally designed to work with nearly all coolant systems.

Oil Catch Can
Oil catch cans and the idea have been around forever. We have taken this idea and added style and an innovative design that fits anyone’s desires. Because our Catch can uses Silicone for the body, and machined aluminum caps for the top and bottom, it can be mounted anywhere your mind desires.

Why do I need an Oil Catch Can?
Lets look at your engine for a moment. Every engine during the normal combustion process, has blow-by. Engine Blow-by is excess combustion gases that leak by the piston rings and escape into the engine crankcase. During each compression or power stroke of a normal engine cycle, a very small amount of gases leak by the piston rings. This happens because the piston rings do not create a perfect seal. This Blow-by of gases is very small, but the higher the RPM and the more pistons, the more the blow-by starts to create pressure in the crank.

This pressure needs to be released, and is done so by crank case vents. Because manufactures have to keep environmental issues in mind, these gases can’t just be vented to atmosphere. So the OEM’s vent these gases back to the intake system to be re-burned. This all sounds good, but Blow by is nasty stuff!

Engine blow-by contains gases and oil from the crankcase. The gases aren’t really a problem, but the oil is. This oily mess coats everything in its path as it makes it way back to the combustion chamber. This nasty oil mess gets into the turbo, then boost tubes, then intercooler, into the intake manifold, and finally back into the engine. As the oil creeps in between couplers and boost tubes, it can cause the connection pop off under boost. This oil then gets into the intercooler coating all the cooling fins. This greatly effects the ability of the intercooler to cool, and the efficiency of it will drop! This will cause a huge loss in power and can cause detonation. The last place this oily mess sees before the combustion chamber is the intake valves. Because of the temp differences and the oil impacting them, the oil will start to build up and form sludge. This adds up over time, and can cause many other problems, and hurt performance.

From this you can see, blow-by is bad, and it needs to be delt with.

How Does the Oil Catch can work?
As describe above the oily mess goes from the crank case to the intake system, and generally through a rubber hose. An oil catch can simply intersects the hose and the oily mess before it reaches the intake system. The top of our Oil Catch Can has 2 fittings, one in and one out. The oily mess goes in the can, gets trapped because of either the media inside the can, or from the change in direction, or from a change in temp. This separated the good from the bad, and collects the bad.

As the fluid fills the can, the end user can use the sight tube on the side of the can to determine when to drain it.

Why would I need more than one Catch Can?
Because engines have more than one crank case vent, and or more than one type of crank case vent, they can use more than one catch can. For instance on a Subaru WRX, there is a crank case vent, valve cover vent and PCV hose. All of these vents do different things at different states of engine load, and in turn, all could use a separate catch can.

Coolant Over Flow Tank
Think of this as an added bonus. Because of our unique design, and mounting system, we added a few more parts to allow the end user to use the tank in many other ways other than to catch oil. Included with the kit are instructions how to replace your existing coolant overflow tank with a PERRIN Coolant Over Flow Tank. Same as the Oil Catch Can, we include brackets, spacers, bolts, hoses, and other things to remove the ugly OEM Coolant tank.

Or let your imagination run wild, and replace any number of other tanks in your engine bay.

Says it requires one to already have the Stage 1 kit. What does the Stage 1 entail?

Interesting, so it looks like we need to make a plate... The BSH one looks not all that great of quality... not gonna lie, Im pretty impressed with everything else they have to offer besides their catch can set up, especially for their price.

I might look into fabricating something on my own to work with the Eurojet PCV instead of the BSH "Stage I kit" and "Stage II kit"

i got the stage 2 from bsh. I have to drain it every 800-900 miles or so.

Their "Stage I" is a PCV fix

[tpliquid]

stage 2 kit comes with everything included in stage 1 kit. unless u get the stage 2 "upgrade" kit which then you will need stage 1.

Could you possibly take pics the next time you need to drain it, of the block plate with the backside, so I can see how they/where they insert the valve fittings into?

[tpliquid]

i cannot do that . it requires me to dismantle the whole thing.

check vortex 2.0t forum. bsh has couple threads on it with pics.

Not being a team player lol, jk. Sweet, thanks, ill check out those threads right now.

I found this install thread, and it was very helpfull, gave me some ideas on how to go about fabricating my own setup:

I just need to check out where I want to mount a can, and the size, shape I need to get.

[vlm7]

I'm running BSH Stg 2 as well. I added the Aircraft Spruce drain plug for ease of draining.

[jbrowngiant]

sofresh- someone actually mounted it on their A3, go check out the thread in the 2.0t fsi forums on the 'Tex. If you're stock, no need for this one, unless you really want it.

[vlm7]

JB - are you referring to OOO's post where he concluded it wasn't worth having Stage 2 and Stage 1 was sufficient? I don't think anyone can conclusively establish the "need" for this - it's a subjective matter of whether you can accept unburnt oil accumulation that may have a long-term negative impact.

[tpliquid]

i actually bought 0000-A3's stage 2 kit lol

[SoFresh]

If I was stock, I wouldnt be discussing a catch can lol.

Ill search for the A3 install, I know how they work, I've installed one on almost every car I've own prior to the A3, most all went stage III.

I simply was looking more if anyone fabricated their own mounting plate for the breather valves.

Their "Stage I" is a PCV fix

Sorry for the noob question. PCV?

PCV Check Valve System

Description of replacement kit from EJ:

The Eurojet 2.0T Check Valve System is a supplementary product to fix boost and other performance issues directly related to your failing OEM PCV system in the early MKV FSI models.

The Eurojet system includes a proprietary 6061 Aluminum check-valve to regulate pressure throughout your PCV system, two 90* silicone elbows, and four clamps.

BSH also makes one. Or you could do a homemade one.

[Panzr15]

PCV stands for what though?

crank case ventelation vale or some crap

"Phat Crappy Valve" The Audi engineers had troubles designing it at the time, I hear the original blueprints were recovered on the back of a pub napkin

Ah I c now

[UberA3]

Here is mine. Everything works just as i does on the GTi just the mounting has to be modified.
