Ecoboost PCV issues

[Tuner Boost]

Best is to only drill pass side (on truck) and use the OEM cleanside barb to connect the line to T to the other. Then run the cleanside line to the upper (filtered) portion of the air box. This allows easy back to stock of desired by only plugging the drilled hole or replacing the one tube.

But we are getting calls every week now from Ford dealers wanting to try these systems and here is Fords latest: (note, some of the explanation of turbo failures is not 100% accurate, it is the constant ingestion of the concentrated water/fuel/gunk burping into the turbo inlet tube if left as is from factory damaging the hot turbine wheels. They are fragile and even a small amount of a liquid hitting the the turbine wheel when at speed will severely damage the wheel).

Specifically though Tracy, I think Panther is wanting to know why both front AND rear intake lines, instead of just one larger vac line to front OR rear?

Such as, why not just attach a large diameter hose to the front vac barb, rather than use two smaller hoses to t into the vac barb and then go to the rear intake line.

 

[Tuner Boost]

Gotcha.

The size of the line can improve CFM of flow, but the ultimate choke points are in the can itself and the OEM PCV/Checkvalve.  We want the amount of suction available from both turbos to maintain the dirty side (foul) evacuation so that is a great point. And all EcoBoost now come with the Monster can larger diameter -8 line so we have done this to both make install easier, and to see if it improves the actual evacuation.  You can get by using 1 turbo for suction as long as the clean side is tapped into the air box (or if a CAI the end or base of the cone filter) filtered side so the suction is not fighting the proper direction of flow. (See painterPats original results).

Good post.

Thanks. Tracy and Jimijak. Sorry I didn't explain my question properly. What I think in my head doesn't always transfer to paper correctly.

Tracy, just out of curiosity. Could we not just vent the clean side to atmosphere? And place a small air filter on that? I'm pretty sure I asked this before, just not sure if it has been answered yet.

Btw I owe you a phone call.

Well I did my first install like you did at first with painters flex. I did not catch anything either. I now have a filter on value cover using the hole left on intake tube for my second vac source.  I'll test that for a while.  Did notice some oil smell now entering the cabin with the value cover not being part of the closed system.

I noticed sometimes having that oil smell in cabin as well with the css tires into the air box.

 

[SHOdded]

Is the smell more noticeable under no-boost conditions, turbos spinning up, or turbos spinning down?

 

[panther427]

no boost. stop and go

 

[JimiJak]

Ditto, stop and go / idle.

Tracy is the factory pcv Check value needed with a catch can only or complete system install. You can get an after market value for around 8 dollars. Would it be of any benefit to get one and drill or some how remove the Check value.

What is the benefit of deleting pcv and going the full-race setup vs the rx can. Is the McNally can the same as the RevX?

FordFox4 if you would be kind enough and follow the NEW members INTRO simply by following this link and the type of vehicle you have,thanks.  Z  http://www.ecoboostperformanceforum.com/index.php/board,14.0.html

As soon as there is any boost detected the IM vac is shut from the integrated checkvalve in the pass side cam cover so there is no removal of the mix. That is why the RX system uses the inlet side of the turbos for evacuation during boost.

This got me curious so I bought the valve. Its an actual old school PCV valve (the brown fitting sticking out of the factory vapor separator) with the valve that rattles when you shake it. They are not air tight seals. Under vacuum or boost air will flow maybe slightly restricted in one direction. These are also not computer controlled like another member was insinuating on the forum.

Here is some sort of valve above the front composite valve cover on my 16 SHO. Also the separator on the rear valve is different than earlier models. I know the 10k miles I have on my SHO is not much but doing an inspection with the CAC and inlet/TB I found zero amounts of any oil.

I still believe the 2016's have an electronically controlled check valve for the cleanside breather tube rather than a simple sensor. What would the sensor tell the ECU that it doesn't already know from the MAP sensors regarding boost/vacuum? The valve could block off the flow of vapors from the engine crankcase to the air inlet tract, reducing/eliminating oil buildup in the intake tract, intercooler, and throttle body.

I think you meant to post a pic of your 2016's PCV and not my 2014's PCV with vapor separator. The 2016 has the composite cam covers and no longer use the vapor separator but still retain the PCV valve.

Can you pull your MAP sensor and check the intake manifold for signs of oil? That would tell you if the PCV system needs an oil separator.

Seeing how FRPP has factory engineered oil separators for the PCV and breather of the Shelby GT350 leads me to believe it is worthwhile to pursue separators of some sort for both sides of the crankcase because the PCV isn't air tight when it is shut.

 

[BlueSHO]

Yes your right wrong pic.(dam phone) I fixed it.

So after driving 221 miles, my JLT has collected about 1 oz of vapor/fluid and nothing that resembles engine oil when it has settled. The ambient temperatures were in the single digits the entire time. Not to question the validity of the Rx system or any OCC, but wouldn't this blowby simply be combusted by the engine? I'm assuming it enters the OCC as a vapor (and not globs of fluid as it has to travel out of the cam cover, through the OEM vapor separator, and condense in the catch can). If the OCC wasn't there, it looks like it would just enter the intake manifold and pass through the intake valves and be combusted. I also installed a breather filter on my cleanside and it hasn't collected any oil.

What I did notice is that I can smell a strong whiff of fuel vapor when cold starting the car. I'm not sure where it is coming from. I can also detect a hint of the vapor seeping out somewhere from the JLT. It's a very faint scent, I have to practically stick my nose next to the JLT to smell anything. After driving the car hard for some WOT tune testing, I can smell the vapor fumes from the HVAC system. It makes the car smell a bit like the cats were removed.

Are there actual quantifiable gains with using the separator and/or cleanside breather on the transverse EcoBoost vehicles? I can see the Rx catching a LOT of blowby, but the naturally aspirated engines are the ones really catching engine oil. All I've really seen with EcoBoost is the milky/clear fuel vapor.

I would focus on the fuel smell IMO.  Did the fuel smell start after the OCC Install ? Does the JLT have a baffle ?

 

[metroplex]

Yes. After the OCC and the open crankcase breather. It's not a pure fuel smell, more of the same type of fuel/vapor that comes out of the OCC or oil fill cover.
