What one is everyone using ? My cAr is stage 2+ S3 8p and I have the pcv delete but thinking about a catch can been told by a few it will help catch some of the oily S&@£ ? Does the tera clean etc work on the s3 ? And what milage age etc should it be considered
Oil catch can ? And few questions

OK....was a bit busy earlier....
Our engine is designed to minimise emissions and one of the methods used is to scavenge oil vapour from the crank and cam case back into the inlet system and burn it in the engine.
Unfortunately,as our engines employ direct injection,the inlet valves are not cleaned by port injectors spraying petrol over them,and this is the result....
After cleaning by walnut blasting,this is the result....a nice clean set of valves.
This is the sort of stuff we're talking about here....
A catch can system like on this old picture will get some of the muck,but not all of it...
The problem is that whilst that system re-routes some of the muck into the can,there is another cam case breather at the back of the engine,which empties into the turbo inlet tract,so the valves will still coke up,and power can be lost.
My pictures above were whilst using a conventional catch system.
There are two solutions...
Firstly,regular decokes at around £150 or thereabouts.
The one that cures it is here...
That's an IE cam cover,which doesn't empty into the turbo inlet,plus a vent-to-atmosphere breather and catch can system.
Sorry for the long post,but it covers the problem.
One extra thing...I changed from the stock recommended oil to Motul 300V,which is rather more expensive,but the amount of muck has dramatically dropped,and oil consumption is also down.

Well Alex looks that you have been working on your S3 a lot! And the whole post is awesome, lot of work, and the pictures and relevant info, and all the tips and hints, great work!! congratulations!!
And one question, what is the PCV function or why to delete it?? Which is the relation with the catch can??
Cheers !!
Thanks a lot.

Thanks...it's been a long journey and not finished yet.
The PCV system as most of us see it,is flawed and prone to fail,and it's primary function is to aid in routing oil vapours into the engine to reduce emissions.
Deleting it will remove the failure issue,but none of the catch can systems other than the IE system will remove entirely the issue of vapours hitting the inlet valves and crusting them up as the pictures show.
IE's system is expensive,but routes both the crank and cam breathers through a vent-to-atmosphere(i.e. non recirculating) catch can.

This is awesome, I'm learning a lot, and which failures are presented when the PCV fails?? Any engine behavior or OBD codes??
By the way, Sometimes ( once a week) the Car losses power for a second, mostly on turns at very low speed , like doing right turns in the streets, and recovering power instantly, have you experienced something like this before??

sometimes when slowing down, like if you were about to park your car, the idle goes to 2K RPMS, when clutching it, for changing to 2 gear to Reverse, not always on second, but the thing is when tou decelerate and clutch the vehic the revs go up, and when dumping the clutch back to normal, could it be the PCV?.
Nope, light does not come up, or the check engine light either, and not always right turns, always at lows speeds about 10km/h, its wierd but it does not show any codes and the failures is corrected instantly

Alex! good evening!
Guess what happened, looks like my PCV had listen to us yesterday!!
It started to do its thing yesterday, more often than regular, erratic idling behavior, with a check engine light, I ran the VAGCOM and this two codes where the result.
1. switch for tensioning strut stowed f 204
2. 01393 sensor for level control (684)
do you have experience on this two??? :S
thanks mate!

Alex has one Oil catch can from "integrated engineering" he says is the best option so far, because it eliminates the PCV and has a atmospheric breather so vapors ar delivered to atmosphere, other brands like forge works but not a 100% cause they still deliver garbage to the inlet.
so if you want to add a Oil Can you have to remove the Charcoal Canister?? what happens with the hoses???
Yeah I know he has a IE one, It looks a nice set-up but I also like the look of them CTS one's which I posted a picture off above ^
I cant physically see anywhere else where you would put it or certainly without it looking bodged and un-tidy, They are the questions I need to know though ^ Also I think a catch can is a lot nicer to look at rather then a ugly Black plastic box and some pipes....

Sorry for not replying sooner....it was a rather bad weekend.
OK....what AMD did for me was to resite the charcoal canister to the space in the left front wheel arch,behind the fog light.
Completely invisible,and very neat.
This shows where the can has been fitted.
Two other points....
Jumbo catch cans = jumbo collection of gunk to empty,but less often.
Most of these systems are absolute sods to drain,so do bear that in mind.
Unless you use a vent-to-atmosphere system,AND delete the rear breather from the cam cover,you won't solve the coking issue,hence the IE system I've used.

Yes they do,and I used one for some years.
It's catches some of the rubbish,but trust me on this....not all of it.
All those pics I've posted with gummed up inlet valves are with one fitted.
They are worthwhile but not a cure.

My S3 has 46K miles I hope my valves are ok so far, but now knowing this, oil catch can will be a must! Could you send us a picture Alex, of where did you put your canister? Thanks

So you cant actually get rid of it completely..? Surely there must be a way....
@LVS Racing - I'll be sure to check out your offers on Friday..

Think I have worked out a way, I will give it a try over the next few days....
....Now need to concentrate on getting my car running again at the minute

Couldn't you just block off the rear breather to the turbo and the return on the pcv side (with the correct blanking plate) let the crank breathe into cam cover as usual, then instead of running the return from the catch can put a filter on it then you've got a vta instead of a recirculating catch can without spending £800 on a integrated engineering setup and having crud getting onto your valves, or am I completely wrong?

Then you've got something that is a bit ghetto but may work,but still has the PCV in the middle of it.
The IE setup firstly doesn't allow crud to build up on the valves.
That's the whole point of it.
I wanted it for several reasons,that being the most important,and with the new valvetrain on the car,plus a host of other changes it made sense to tidy the whole thing up properly.
What PCV delete do people think is best..?
I cant afford to replace the whole system and my PCV valve is failing I think so for now I just need a quick blanking fix....

The Forge system is very well made,and works as it should.
Customer service is also excellent.

Hi @S3Alex
I've been reading allot of posts on catch can systems recently and the IE system you mention is obviously the solution.
I'm not far from having a stage 2+ Map on my S3 and wondering if I could ask you a few question about the fitting of the IE system and the important a of removing the PCV valve?

OK....the full system consists of the billet cam cover,plus a vent-to-atmosphere breather and catch can,such that ALL of the engine breathers are taken out of the inlet system.
There are cut-down versions using a blanking plate for the rear cam breather,and IE would be the best to contact for that.

So does the billet cam cover from IE not have the rear breather and only has the vent to atmosphere breather on the top of the cover?
Hope you can make sense of what I've said lol still learning (y)
Also, would I need to decoke the the valves after fitting the IE system? Or would I only need a decoke if I were to use a conversational catch can?
Thanks.

Spot on....
On the pics above you can see the cam breather outlet,and the crank breather has it's own piping to the catch can.
I'd advise having the inlet valves cleaned if they haven't been already,if you fit something like this,as the valves will then stay clean/

Brilliant!
Is it an expensive/big job to have the valves decoked? I think it's something I will invest in (y) could you recommend anywhere that will do the job properly? There's a fair few dodgy places around here -.-
All I'm doing with my setup is using a pcv delete plate on the front and routing the rear breather onto the catch can and blocking off the the breather hole on the turbo, then putting a filter on the can itself, I may reroute the filter to avoid cabin smells, but essentially it's VTA setup for a fraction of the cost, I'll be doing it next weekend so I'll put up a guide or a few pics to explain

It's not expensive but it is fiddly,so I left it to AMDTuning to sort it out for me.
