Ecoboost PCV issues

[bpd1151]

LOL @ ShoBoat.....

I absolutely love your rationale as it relates to FMC installing Methanol Systems from the factory.

TunerBoost thank you for the continued replies & coorelating info.

Well articulated on your end as well. Bravo good sir! :clap2:

Please keep the community posted as to what ever you find out specifically with PainterPatt's installation, as well as any installation tips that you may have for each of the EB platforms.

Will do. And although meth injection definitely helps reduce the coking issue, but does nothing to reduce the rest of the gunk entering or accumulating in the crankcase and engine oil (the post where I quote a recent oil analysis from Blackstone shows that).

Pulled a CAC today to inspect and clean:

This is not a Flex or Taurus, but a 2013 F150....and it shows oil/gunk in both the inlet and the outlet tubes, so a good deal has been ingested.

And anyone can feel free to ask any tech questions automotive related, not just this subject. I'm not on here very often, but try and visit at least daily.

Wow, that is allot of oil for a gas engine.  Going back years, the Grand National had the same issue, we would have to pull the CAC every few months and clean them. 

You would think that Ford would know how to make a CCV system?

Now if those pictures were from a 6.0 PS i would think it was normal

Hey Tracy, how many miles in the F150 in the pics?

 

[Tuner Boost]

Not sure on the miles...but installed the RX system app 1000 miles ago so there was no water as usual, and the can has been catching a ton of the gunk mix, so only oil was left in the CAC. Putting on a new aftermarket intercooler so will track this to confirm the RX keeps all oil from it.  We will get the owner to come back later to do a manual intake valve cleaning and document it as well.

We did before dyno and will do after to see what difference the intake valve cleaning does.

Also, had a hydro lock engine we tore down yesterday......looked fine from the top except some slight scouring on the cylinder wall, but when we pulled the pistons here is what we found:

Ingested a slug of water and had a misfire...compression test showed low but boroscope all looked good. dropped engine out and removed heads, still looked good except a few score marks.  Found pieces in the pan so popped pistons out and bingo. But it still ran half way decent and NO knocks or noise. 

 

[ShoBoat]

Holy crap! That's nuts.

 

[panther427]

That is flipping insane. It so odd what can happen to a motor and yet it will keep running and other time small stuff goes and causes a completely blown motor.

 

[68_GT]

So if I run a rx catch can I will have to drain out 12 ounces of gunk out of it every 150 miles and if I don't I'm running the risk of gumming up the inside of my engine, hydrolocking it, or thinning out my oil to the point of a catastrophic failure !!!!!!!!? seriously !? ugh !!!!

 

[SHOdded]

I don't think the situation is THAT bad but regular maintenance per your driving style is a MUST.  I always equate frequent performance driving to a severe duty schedule.

 

[68_GT]

did you see how much crap poured out of that can after 140 miles lol ! Seems like all of these engines with out a catch can would be destroyed all the time.

 

[SHOdded]

True.  Maybe boost multiplies the problem.  Maybe we should instead be looking at a PCV atomization-direct injection system to burn all this stuff in the combustion chamber!  I mean if Mercedes can have 2 spark plugs per cylinder, why can't we have 2 injectors, right?

 

[68_GT]

great just another thing to worry about ha ha !

Let's keep in mind that the turbo seals on the EBs and every other turbo engine out there are known for leaking. At least a little bit, that may not all be from the PVC system. It seems a bit much just from the PVC, if that was the case these engines would not run for long at all lol.

 

[Tuner Boost]

So far, the cars do not seem to have anywhere near the amount caught as the trucks, and I suspect the intercooler has something to do with that as the truck gets a ton of air flow past and seems larger capacity, and that video is in below zero weather and anything below 45* F results in much more water as part of the mix. The shop truck we track we are still getting app 4-5 oz's a 1000 mile week out of, but were here in FL and temps are mild. In the 40 degree weeks we had in Jan/Feb we got twice the amount per drain, so until we have more results from the cars (have over 250 on ecoboost trucks, but only a handfull on the cars) we cant judge the severity of  or amount on average caught. You want NO oil ingestion on a DI engine, but I am suspecting the cars will have far less of the water, and there are stories from techs at Ford dealers seeing trucks hydrolock, but I have yet to hear of a car doing it (unless a low mount CAI scooped up water in a deep puddle).

Some times we see small seepage from turbo seals, but the 250 plus EB's we have the RX system on the past 3 months have zero oil now (or water) in their CAC's (the ones checking) and the amount they keep catching is substantial. 4-8 oz's a 1000 miles or so. Also, oil leaking from a turbo seal wont be routed through the can to catch so it would be both in the CA and as when a seal fails, it is generally hot and cold sides due to shaft play, exhaust smoke is a sure give away, but not always.

...and don't confuse the sooty exhaust tips that all ourn SHOs have with smoking exhaust....

 

[ShoBoat]

In the vw diesels they put drain plugs in them lol. There is a vid on YouTube of a guy draining 1/2 a quart of oil from the cac from leaky turbo seals and that is normal.

you alchy!    LOL

 

[SHOdded]

That's another thing to look out for.  Does the catch can system cut back/eliminate the chimney-smoked/coal-mined look?
