Get a Bob's Catch can if you haven't already...

[C0bra99]

Screw it. Since a little oil won't affect the intake tract I decided more oil is better. I have tapped into the oiling system and will feed it directly into my intake(making sure the oil is downstream of the filer can't be too careful:thumbsup. More is good right? And since there is no documented failures only picture proof of reduced performance these must be BS and more oil the merrier:banana::banana:.

Love the Tickle, that show cracks me up for some reason.

Van, You could roll your car through Ford service with a KB installed and probably not get any comments. It all depends what you are there for.

If you go in for an engine related failure or problem, I bet you would get a comment or two on the separator or anything else for that matter that is not stock. I would personally never take that chance and I doubt too many people on here have the balls to roll the dice with service on a $17k engine.

If you are having engine related problems, I bet 99% of your customers (gotta leave room for mullens...i kid, i kid ) will remove the separator before they go in for service.

Yeah, I had a KB on too! LOL

Tony, This is an excellent question and yes you can find a bunch of pictures online that show oil residue covered intercoolers from lightnings and mustangs.

I have a better question though. Does anyone have a picture of an intercooler after 5-10k miles with a Bob's catch can installed?

How efficient is this catch can anyway? These cars produce a lot of oil vapor. How do we know if the catch can is really only distilling 5% of it and that 95% of the crankcase fumes are not heading right back into the engine to "foul" the intercooler and degrade our fuels octane rating?

Don't show me the 1/2 ounce that is caught after a few thousand miles, show me the clean intercooler. :thumbsup:

Great point. I do not believe there is a separator that is going to be 100% effective. If you are still returning the PCV to the system some will still get through. The pictures and documentation presented on this thread and other threads for the Bob's Separator have shown that it does in fact capture more oil than any other separator available at this time. Time will tell what we see over the long haul.

Why not just vent the top line of the Bob's catch can into the atmosphere and put a small airfilter on the intercooler side?

This was my set up on my 2007 Race GT500

All returns to the intake system were capped off and lines run to the catch can with a breather.

You would probably be violating EPA Emissions Regulations by venting oil fumes directly into the atmosphere.

On the test mule pictures with the catch can installed, again let me take the other side of it. How do you know that the engineers didn't install the catch can for testing, only to find that it didn't add any value, so they deleted it from the production cars. This line of reasoning is way more logical than the idea that they tested it and saw how effective it was, and decide to remove it from the production vehicles and screw our intercooler efficiency.

That particular car spent time in Germany (where the underhood photos were from) and was used for high speed testing (among other things) at the Nurburgring. They weren't using the separator to find its value. They already knew why they wanted it in place. It wasn't about considering it for production as that is handled by an entirely different group within Ford and those decisions have or had already been made. The powertrain already met Ford's own minimum standards without it. What you see the engineers using isn't a Ford piece. Again...

Believe it or not, that piece was made by Husky for Home Depot for use in air compressor systems (as many have tried to adapt for pcv system use). The design of that particular part has changed recently but Home Depot still carries something similar. And since the engineers probably didn't find a Home depot in Germany, they most likely had added the filter stateside, before the trip overseas.

The engineers simply used it to keep the engine at peak efficiency. Plain and simple, that is all that this mod is about.

The Bob's Oil Separator is constructed as follows:

The PCV line from the top of the crank case breather goes into the lower portion of the separator. The lower portion of the separator is filled with a medium for the oil to be captured as the gases rise up to pass through to the return side.

The separation between the upper lower portions of the reservoir as seen here.

This is a picture from the prototype but it is essentially unchanged. The billet aluminum separator has a groove and snap ring for the medium to be retained.

Assembled.


For the record, I rolled mine through Ford for service with separator installed. No comments. Having the spare line is merely one individuals choice. I've sold a number of separators. I have two customers to date that asked me to supply an OEM replacement part because they didn't want to cut the OEM piece. Not for warranty concerns but as much as keeping the OEM unit.

As for Tickle from Moonshiners designing an oil separator................leave him to his special prowess however a large mason jar of that liquid he creates would go a long way when one wanted to clean an oil separator, among other things!

Informative post. This should dispel any fears of the media getting sucked into the intake.

Van said I made a "Great Point"!!! Nice :beer:


TOB, I bet those engineers doing the Nurburgring testing were not concerned about warranty coverage either.

BTW: How do you know so much about what that car and those engineers were thinking and doing over there? Do you work for Ford?

Take care,
Kevin

We could tell you, but then we'd have to kill you! :beer:

I am a Ford dealer (Westland Ford, Ogden, Utah), and while I can't speak for other dealers, I can tell you that no matter what the issue is you're bringing your car in for, an oil separator absolutely will NOT effect any part of your vehicle warranty in our shop. Unless, you're trying to warranty the line itself. You know, the one that gets modified. I have a sneaky suspicion that no other dealer will have a problem with an oil separator either.

I can't tell if the opposition to this separator is from a possible warranty denial, or from the doubt of its function. Either way, I think there is more than enough information in this thread alone for any reasonable person to conclude its need.

ObieFox - good question!

"I have a better question though. Does anyone have a picture of an intercooler after 5-10k miles with a Bob's catch can installed?

The only way you are going to prevent 100% of the oil from entering the intake is to go with the setup that Van uses on his 2007 Gt500 racecar. Short of that, Bob's seems to be the best choice. Unless someone can show me that installing an oil separator on my engine will cause damage, I am going to install one. As far as I am concerned, less is better when it comes to oil in my intake.

Well I think Obie addressed that before with the BMW failures.

I mean it's like any part. There's always a chance for failure.

So if your catch can did fail and caused an issue with your motor then you wouldn't have warranty protection. I think that's all he's trying to say.

 

[railroad]

I would like to see a second separator on the same line and what amount of oil it would catch. Any takers? I would think the cooler the bottom of the separator the more efficient it would be. Would it be worth it, to plumb it toward the front of the car?

There is a chance of failure with any part, OEM or not. But after looking at the construction of Bobs separator, I'd say it's as close to zero as you can get. What's to fail? No moving parts it's basically a screen, a canister and two hoses. That snap ring looks pretty stout to me.

Yeah, but OEM you're covered by warranty... that's the point.

Wow. The 'good question' above is exactly what I asked during my earlier posts before being labeled a stubborn, brainless doubting Thomas. All I wanted to know was if anyone had a quantitative, scientific comparison to substantiate the effectiveness of the oil seperater in improving vehicle performance and/or longevity.

I have one more question: what 'medium' is used behind the screen being held down by the snap ring? ....(panicking) please don't kill me. I believe, I believe. I even renamed my oldest son Bob in honor of the oil seperater. It's just an honest question that any interested consumer might ask. Have mercy...!

 

[ObieFox]

mustangc,

You were not labeled a stubborn, doubting thomas.

Actually, it has been implied that we are unreasonable, shortsighted, non-butt wiping, half brained, ranters....

Sorry, I couldn't resist doing the summary.

Those Ford engineers are an unreasonable bunch of rabble rousers, eh?
