BFI - Clean Catch Crankcase Oil Separator - for 2.0T TSI!

[jpsgroup]

Have unmodified 2009 passat wagen w/2.0 TSI. Based on all threads written...is it a forgone conclusion I will experience rhese valve depost issues? Does purchase and install of your discussed PCV catch device affect VW warranty? (60K powertrain?) I have no known problem at the moment, however would prefer to avoid this issue altogether. Please advise? Thanks.

[maotsetung]

Yes. You will experience the valve deposit issues..unmodded or modded. Even with or without a catch can like the guys have said. Only way to properly clean is through personally or professionally cleaning the valves by removing the intake manifold.
I'm not really familiar with the powertrain warranty nor cared much, which I should. So someone will most likely chime in on that.

Thanks to all for various input and solution paths. I am no expert, however, seems reasonable that with one VW TSI engine type in USA service, there should be one ideal, tried and proven solution for this problem? I read several methods. I'm not trying to be critical, but would welcome the definitive fix to this TSI problem w/o trial and error. Unfortunately, I have limited time in which to impliment VW fixes so "the real fix" would be welcome. Your thoughts? Thank you.

The problem is that ultimately there may not be a single solution to the problem. VW/Audi are addressing this with upstream extra injectors on the next generation of their direct injection engine, but that won't help the existing platform. The best scenario is to mitigate as many of the problems that you can (ie with the installation of a catch can) and to fix the problem areas as they arrive by cleaning the intake tract periodically - either by the use of a fuel injection type service, or a more effective physical cleaning.

Will a catch can stop all deposits on your valves? No. But the pcv is a significant source of the oil/oil vapor deposits on the intake ports of DI heads. Valve guide leakage is present, but not the main factor. I will put together some videos to demonstrate what I am talking about (having a catch can with a small dipstick port helps to show what the vapor actually looks like while the car is running).

We did run some unscientific tests using lubro-moly valve clean (ventil sauber) using the head pictured in our original thread posts. We found that when letting the solvent sit for about 15 minutes, it started to soften the depostis and alow them to be easily brushed away. A 24 hour soak actually showed some removal of the deposits without and physical cleaning. Of course this doesn't directly translate to a "seafom" style treatment, but does show that the solvent will loosen the deposits, its just a matter of time (either soaking or multiple back to back treatments). Of course the only sure method is to physically clean the valves by hand, but I wouldn't say that there is no efficacy to inducing the solvent into the intake port periodically, especially if started when deposits are minimal.

Will the AN fitting and special clasp also work for the rear PCV port?

[pete@blackforest]

Will the AN fitting and special clasp also work for the rear PCV port?

On the TSI engine, no. The rear PCV port is plugged with the kit.
The can is setup to connect to the front PCV port and route to the connector on the intake.
The front PCV will always stay open because it will always be under vacuum, eliminating the need for the rear PCV port.
Even if you attempted to connect the hose to the rear port, it would not fit. The connector on that port is a different design and would not accept the clasp.
If you have anymore questions, please let us know.

Pete, do you know how much vacuum is created in the intake tube? How does that compare to the vacuum in the intake manifold (which we blank off)?
Cheers

The vacuum inside the intake tube is less when compared to the intake manifold, however the amount of vacuum is consistent enough to allow the passage of gases through the PCV valve to the Clean Catch can and subsequently back to the intake tract.

Thanks to BFI I purchased the needed AN fitting and clamp in order to run the front PCV line as a dump tube straight to the ground.

Sorry for the bad pic, I was in a hurry and didnt notice the pic didnt focus:

oh and I cleaned up the end of the braided hose so it looks purdy


losely zip tied the end of the hose to the W.A.L.K.:

Just curious, from the engine bay pic it looks like the rear PCV hose is still connected? Does that also go to the ground or is that still plugged into the intake tube?

[ViRtUaLheretic]

The BFI adapters don't fit in the rear PCV otherwise I would have done the same thing (cept I would have used braided stainless hose for that) as I did for the front pcv

[Ricky Bobby]

VIRTUAL, looks good man!

now you just have your VTA catch can with the rear PCV connected to it right?

[ViRtUaLheretic]

Correct
If I can find an adapter for that I would buy that as well and run a dump tube down near the exhaust (I would use a braided SS line for that though)

That looks really ghetto

But seriously, the hose ziptied to your w.a.l.k. is just venting the crankcase gasses and not fluid, yes?

how do you guys recommend emptying the can? Unscrew it, take the bottom plug out, and drain, or take the top off?

Removal of the bottom plug is the easiest way to drain the can.

Most people will loosen the canister from it mounting point on the engine bay, lift the canister, then remove the bottom plug and drain into a container for proper disposal.

For those customers that might want to make the process a little simpler, you could replace the plug with a valve fitting and attach some sort of hose for easier connect/disconnect disposal.

anyone know the the part number for the pcv plate gasket?

I know this is the TSI forum, but for clarification sake are you asking for the gasket number for a TSI or FSI?
The reason I ask is because with our TSI Clean Catch, there's no need to replace that gasket.

Anyway this would be helpful on a 1,8 t 20v with some mod to connect it?
