Turned out much easier than expected, mostly because I happen to have everything I needed laying around in my garage and all parts fit. Random coolant hose with all the bents that it had, made a perfect fit for the catch can location. Wish all
custom mods were this easy

 

Well done Alex, am wondering if anyone's installed in a 5.0 yet?

Thanks again for documentint

 

Yes it has:

Alex, interested to see just how much oil you collect.

 

This has been on my To-Do list for a few years now. Eventually I will get to it. Sooooooo many projects around the house these past three years. And I STILL can't get my garage built...... <rant> Dang stupid Permit Problems. I gotta have both an Architectural Engineer AND a Structural Engineer sign off on my plans.... but they won't. "Insurance forbids me from stamping any plans that I didn't do myself, plus I'm swamped until March 2021".
Yeah, plus the $2400 bucks EACH to do this.
Bite me, I'll build it and take the fine.
</rant>

 

If the fine costs less than the engineer fees, seems like the way to go...

 

If a person gets caught, the city gets an engineer to make a site visit and do all the calculations there. Costs MORE that way, I'd think. The savings would be the enormous TIME saved by all the waiting. Six month backlog? Yikes.

 

Help me out guys. I can research it via google too but why not just replace the PCV? I'm not being critical. Just trying to understand why it becomes advantageous over time vs. replacing the PCV. I understand Alex's comment based on his tune and increased power, that the PCV is no longer sufficient, but others have added the to stock vehicle and therein lies my question

 

The stock PCV system sucks oil vapor out of the crankcase. That oil gets recirculated through the intake and then burns onto the BACK of the intake valves and turns into carbon and other nasty gook and crap. Intake valve deposits are a deplorable bane of Direct Injection Engines, and also sometimes a problem on wet systems, but nowhere NEAR the GDI problem.
Search GDI intake valve deposits and you will see some REALLY nasty stuff.
Oil Catch Cans remove a LOT of oil from the vapor and thereby vastly reduces the intake fouling problems of GDI engines.

 

I I suspect that even in the stock car they're still plenty of oil getting sucked back in. And as to the PCV system , I have seen somewhere that it's not actually a PCV but an oil separator, I will tend to agree with this as the valve allows flow both ways, It's interesting if it actually closes at any point at all. if it's just an oil separator which stays open the catch can will definitely help even more than with a PCV system .

 

I went with the black hoses at first too, then I noticed the vacuum was collapsing them. Switched to a clear, hard hose instead.

Wonder if you will have that issue also...

 

Read through the whole thread and was expecting to see a parts list

1) Catch can used for a 5.0, min capacity recommended with top access for vacuuming out deposits when emptying is required
2) Width/type of tubing used without swelling/distortion problems
3) Mounting point on a 5l
4) Recommended change of parts (e.g. new PCV) at the time of fitting

None of those were answered, but thanks for the effort of posting the link

 

Well ‘twasn’t my thread but the subject had come about before...

 

But no point sending others on a wild goose chase?

When/if I find out what is required I'll complete that thread with the missing salient information

 

1) Around 250mL @ 6000 miles, shop around for one that fits.
2) You'll have to disconnect the stock fittings and figure that out on your own
3) Post #17 in the linked thread OR same spot as OP and myself
4) I believe PCV valves are integrated into the valve cover on 5.0 so probably not worth replacing. The replacement hoses are no longer available (at least not for the 4.2) so you'll have to make your own fittings/hoses.

 

150mi Update:

 

I'd be interested in doing this if I knew what hoses to use etc. I'm surprised no one has done this on the 5l.

 

oops, delete

 

You could use my first wife...............

 

@AlexJag Thanks for this!
I recall having this debate with @Queen and Country a ways back... he gave me a great education. He's been very quiet lately. Is everything ok?

Cheers Friends!
Guy.

 

Ugh. Let sleeping dogs lie.
As far as a Catch Can or two, I've been planning this for awhile now, just haven't yet.
