A sometimes unnoticed remedy of having the catch can on the hot side of the air system is oil suction directly from the valve cover. This is what causes oil in the intercooler. When in boost especially hard left corning the turbo sucks in oil from the valve cover via the crankcase pipe that goes to the side of the turbo inlet.
You probably dont give a shit but does anyone know of a trick to get back into an Instagram account? I stupidly forgot the password. I would appreciate any tips you can give me.
@Alberto Daniel I really appreciate your reply. I got to the site thru google and Im waiting for the hacking stuff atm. I see it takes quite some time so I will reply here later with my results.
How the pcv works on th B7, when idle, in a vacuum state, the pistons suck air(through air intake system) and crankcase vapors through the diaphragm valve(pcv) atop the valve cover into the intake manifold. When in boost, the diaphragm closes off the intake manifold side and crankcase vapors get routed and sucked through the turbo inlet via the the flex aluminum crankcase vent pipe which connects to the valve cover. As you can imagine, having the turbo in boost sucking in all that air under high pressure, it will suck small amounts of oil as well, very little at a time, but ALL the time in boost so it adds up. Low oil levels because the oil is going into the intake system, pooling in the intercoolers and then burnt in the engine out the exhaust.
So permanently closing air travel in between crankcase and intake manifold wouldn't that choke idling or in longer period of time even blow rear main seal?
@@Chamo-zh1co yes exactly. Although from experience the turbo seals will give before the main seals. When the turbo seals get compromised, you will see oil smoke out the exhaust at idle(and all other rpms, just very noticeable especially at idle). The oil return from the turbo to crankcase, returns by gravity only, so when there is back pressure from blocking all the crank pressure, the crank pressure blocks the turbo oil return line forcing the oil through the turbo seals, and then out the exhaust as ALOT of smoke.
@@Chamo-zh1co the idle itself won't suffer per say, but the crank pressure will not be adequately relieved. This is what will blow seals in the long run. Running blocker plates and catch cans is a delicate setup that has to take alot of scenarios into account.
Installing oil catch can is fine like you did but undersized hose diameter and blocking lines from crankcase to intake manifold possibly can blow rear main seal isn't that true?
Hi I had a audi a4 b7 2.0tfsi same as your red audi. Can you tell me the advantage of pcv delete with catch can installed, and dis advantage. Engine, turbo and oil consumption.? Do youb recommend this to make engine better and last longer. Some youtube vloger not to advice pcv delete and catch can, some would recommend, so which is better?
Its best to supplement the oem system. Meaning leave the pcv on, and put two catch cans on either side. In between the valve cover and turbo as in the video, as well as in between the pcv and the intake manifold.
@@aydendeuchant9165 same concept as the other side. Pcv to catch can, catch can to intake manifold. Where the other side would be valve cover to catch can, catch can to turbo inlet.
The reason why the cstch can only catches water is bcs the catch can doesn't work 100% its actually useless.. i ran on my 2.0 tfsi 2 catchcans and still you can see the line going back to intake is oily inside .. i run them vent to atmosphere and i block the intake side. Thats the only way you know the oil doesn't go back to intake
Do you vent under your hood? This will get sucked into the cabin air system and you'll be smelling exhaust fumes inside the car particularly while at stand still. A good vent to atmosphere idea would be to route both pcv side(after blocking off the intake manifold end) and turbo inlet side(after blocking off the small opening at back off the turbo the inlet) into a small pipe welded into the exhaust system at exactly 45°. The angle follows air flow principles where it will not allow exhaust flowing back up the pipe into the crankcase. This is further supplemented the faster the exhaust rushes by, it creates a vacuum sucking the crankcase gases out.
hey what are all the hose, fitting, and adapter specs. my vent is 1 inch and the catch can is 3/8 inch and there is no reducer for that so just wondering what your parts are thanks
Stage 3 would be all that plus full exhaust completion, headers, fuel injectors and a upgraded turbo. But you’ll have to buy another tune for stage 3 so that your headers will work properly with your fuel and air ratio. Bro your gonna have to do your research
Dayum, B7 channel. I’m in bro 😎
Is there a vacuum in the crankcase when the car is running any you take off the oil cap?

@Alberto Daniel It worked and I finally got access to my account again. I am so happy:D
Thanks so much you saved my ass !
@Elisha Enoch glad I could help xD
Hey where would I be able to find one of those intake cap???
Question can you run a catch can and a pcv delete?
Like this set up better than my $300 cts set up...🤔🤔🤔
Which way is In? The hose from top? Out is the turbo?
What size is that 90deg adapter

@@fcbotieno I agree and that's true thanks bro.

No response so i have to unsubribe.
I heard they mess with the turbo and leak into them if not done correctly

Probably not bro, it’s just a oil filter basically

hi mate what is mods for stage 2? turbo upgraded?
That’s the link for all stage 2 equipment, lots of money but it’s worth it. I did it and my car sounds insane

Please let us know how often you topped up oil before and after the catch can. Thanks.
B7 A4 2.0t Q 6speed titanium US spec in GTA, Ontario
Every 1,000km I need maybe 200-300ml
@@MarioKay ok, with no catch can I top up 1000ml every 1000km.
Empty 400ml pure oil every 8000km from the intercoolers.
@@MarioKay how about now
Is the stock pcv still on ?
No
Have you ever emptied the oil from your intercoolers, left and right?
Yes, when I did my new front end installation. There was quite a bit of oil in both of them 😳
What it suppose to do?
Any issues with this setup?
Nope
Normaly the oil cacht can goes in the PCV
Any issues or she's still sweet?
Thanks
It freezes in really cold weather and don't recommend for winter
Yes yes more videos. How to do
. Hey, it works fine, I think I will buy it too
