What have you done to your Audi A4 B7 today?

how's the catch tank setup behaving?

Well, it's there and working, but I still get smoke after starting from cold.
So start the car all good, but after being on tick over for a few minutes the smoke starts, then clears after it starts to warm up.
I no the catch can is better, but I did not have this before I installed it???
I did clear the oil from the intercoolers, so I'm a bit stumped.

If you are getting smoke on cold start-up only then it's possibly that oil is getting into the combustion, normally its valve seals letting some small amouts of oil to get past which then burns off quite quickly.
I used to have the same problem with a V6 Vectra, when starting in the morning it would smoke a bit when cold then clear quite qucikly, valve stem seals were the culprit.
Could possibly be some residual oil still in the intake pipe getting sucked back in, but less likely and you'd get it when hot too.
The only way you could eliminate the catch tank from the equation would be to revert back to the OE setup and see what happens.
There have been cases when excessive vacuum can suck residual oil back into the intake but not seen it myself and not encountered it as yet, certainly not an issue I have had with my installs.

how sooty are the exhaust tips?
maybe worth a look at, or we can meet up and i'll have a look Richard.

Hi Rob,
I am bit baffled over it, and it's a bit embarrassing to see the car smoking like that.
Yes I would like to meet up when you are free?
 
just refresh my memory Richard, is yours a part PCV bypass with catch tank or full PCV delete with catch tank?
 
Haven't posted in ages, but wanted to show off my new invention.

Scrape ice and sit there waiting for the windscreen to defrost

Ah , so you don't have the quick clear option then.:whistle2:

Well to be fair it does clear pretty rapid so not sure if it is because of the blowers or if I have a heated windscreen...wonder if that is under the options list. Just wondering because I had a new windscreen fitted only last week
I do have the heated washer jets..
 
I'm a big fan of the SCSI bus in all its different mode , messed around with HP-IB stuff back in early 90's

i seem to recall this method was used with the folding mirrors too.

Yes it was. But now im going to TRY and hack the Can Bus and maybe somehow implant the code into the original controller.

Hi Richard, it's very unlikely to be that to be honest, the part delete is just a filtered bypass setup for all intensive purposes.
Any oil particles in the airflow will be retained in the catch tank and the micron gauze filter reduces to allmost zero anything being returned back into the turbo and back to the intake.
Whats the idle like , smooth or lumpy?

Hi, Idle is spot on, does everything it should, cant get my head around it, all running well and drives spot on, boost is good and pulls really well
and fast acceleration.
Exhaust tips are sooty, but my son reconds all remap engines tend to have this.

Yes, remaps and fuelling can account for the sooty tips.
Maybe not ideal in the current weather but you can get a good idea of how much oil if any is getting directly into the turbo via the cam cover setup.
 
This is what happens with the OE PCV setup in place, all that ends up getting dumped directly into the turbo.
With the PCV bypass and catch tank, it shouldn't, well it's impossible to eliminate every last bit of oil-saturated air from the PCV but you should not be getting anywhere near this amount if you are then something is amiss.

What pipe is that? I'm guess the one that goes to the turbo,? is it worth checking for oil.
I have left the Catch Can drain open, would this cause anything.
 
it is Richard , from the valve cover.
Worth removing and checking without a doubt.
Since going the PCV delete route I've not had anywhere near the oil residue problems, IC pipes have been clear etc along with the return pipe to the turbo.

In a full pcv delete that pipe is removed and replaced with a blanking plate.

End result is that all this gunk is kept out of the engine and more importantly not fed back into the intake and combustion cycle.

Braved the cold today and fitted an 034 motorsports snub mount and cage. The old bush had certainly seen better days and the OEM cage looks excessively big.

The polyurethane foam oem item is only good for a few years at a time.
For those that want something better than the oem bung but not quite as firm as the 034 or power flex items, the A6 bung is an excellent compromise

Its been a while since i've messed around with it , but just remove the rubber turbo intake pipe so you have better access to the two screws securing the metal flexipipe to the turbo , and remove the top fixing and thats it , of comes the pipe.
 
with the pipe off you will be able to see inside it if there is any oil residue ,and with the rubber turbo intake pipe removed you can see if whats its like in there.
 
Hi all,

Just got an AV upgrade on the car finished.
-Kenwood DMX8020DABS head unit with DAB aerial
- JL Audio C2-650 FR component speaker set for the front
- JL CP110LG-TW1-2 subwoofer/enclosure
- JL Audio XD500/3v2 amplifier running the fronts and Subwoofer
- JL Audio RLC remote bass level adjuster for amp

No pircutres of the font speakers as they are just behind the OEM grill. Sub is secured as you can see with a bit of bungee.

Front doors and boot have been soundproofed as well.

Can’t beat a good audio upgrade, the OEM setups on these cars are poor even with Bose. I’m running those JL C2 650’s in the back on my system, good speakers. Dynomat’ing the doors is a must when running an active set up, sounds so much better with sound deadening :rock:

Yeah the soundproofing has made a crazy difference. I am super happy with it.

Next step for me is stage 2.
