my latest project Oil Separator block off plates

[Vedubin01]

I have been in and out of this project for almost 2 years. And finally seeing the light at the end. I wanted to build something that would allow case pressure to escape faster, not recirculate burned gasses oil and what not back though the intake, and lastly remove a wearable part with something you would never need to replace again. Wanted something that would hopefully help increase power, and extend rings and gaskets for our S65 engine. I have toyed with different designs but settled on more of a factory plate design. I've posted here and there on FB and my IG page but figured Id start a thread here to get feedback etc. I will be making a small run of these to help offset the project and there will be more info on that after testing. But anyway I thought I would share where I'm at now.

I am currently working on a factory mounting point bracket for the catch can and once that is complete it will be ready for testing.

Flame away!

So, this is a mount for an oil catch can?

You still have to remove it to pour out the watery/oil goop, ya?

These are the oil separator block off plates. The bracket I'm working on would move the windshield filler hose over and mount to the clip on the strut tower.

The catch can has a valve and a line that you turn to drain out the end of where ever you route the line to.

Cool. How is this better than just a regular catch can installed inline the PCV line?

Love it!

Can you put me on the list for the small run? Thx

Hey could you explain to me how this is better than just installing a oil catch can inline the PCV line?

I'm not an engineer, so this is best answered by someone more qualified. On NA cars the existing Oil Separators or more than sufficient to recollect the oil vapors included in the pressure relief and thus no catch can is needed. For FI cars, the pressure is greater and thus the additional protection from a catch can will add more filtering of the air before it's recirculated back into the intake.

In this case, my intention would be not to recirculate oily air back into the intake period. Id also like to delete the secondary air pump. These are emissions components which are essential for street application. My build continues to march in the direction of track only and thus I'd like to remove all extraneous parts to simplify and streamline the bay. I'm not there yet, but a well machined piece is one less item I need to have made.

Make sense?

Almost makes sense… Saying that in this case, the intention is not to recirculate oily air back into the intake, but that's what a catch can is for… to filter that air, so it wouldn't be oily.

Is this working under the presumption that an oil catch can will not filter all of the oil out of the air?

The oem separator does this already. The catch can would be a secondary redundant system.

I'm deleting the recirculation.

See if I can answer some of your questions. Why this vs say the PCV valve catch can. I've seen some old pictures of race cars using a block off of this similar design and that's what got me thinking. When oil separators fail you get higher pressure, more oil burn, and could be a cause of valve covers leaking. Higher pressure wears on rings and seals and essentially robbing HP. The separators dump a lot of spent gasses back though your intake, along with water fuel oil etc. I've taken off my plenum several times to see my throttle bodies gummed up etc. my car has just over 50k miles on it. I wanted something that would replace wear items such as separators ($80-90 each) and replace them with something I would not have to replace ever.

As for the catch can it could be completely up to you on how to route this. You can route from these plates to your catch can back into your plenum. You can route from your catch can to atmosphere, or you can route from your catch can to your exhaust creating suction on the system.

The lines are 10an and will give ample breathing to your engine, not allowing much or any pressure to build. The Nuke catch can has an internal filter and the ability to run an exit line out.

Yes this is intended for racecar or off road use and is a product that is intended to remove epa products factory installed on your car. So do what you wish.

For me I don't want exhaust gasses etc being rerouted back into my intake. I don't want any pressure in my case that would cause wear either on my rings or gaskets. I don't have an issue with burning oil but this could solve that as well. And lastly it will look much better and clean up the look at the end of the day.

It was just a project that intrigued me from years ago posts and pictures of race cars running the s65 engine with no oil separators. Hopefully soon I'll be able to do some testing and report more info. I plan on running a base run on the dyno this Saturday and going from there.

Feel free to ask questions. I'm no astrophysicist, just an airline pilot that loves my car and always looking to improve the driving experience.

Thanks for the details.

I remember you talking about this years ago, and I believe your initial plan was to route it into the exhaust, no?

It's cool to see how it has evolved.

Will installing this trigger a check engine like OBD code? Still pass smog?

It should not trigger anything as there is no sensor in the oil separator

How much will it cost to get in on one of these kits?

[Redd]

Looks interesting. What about the hole on the plenum side?

I'm still in testing phase but once I figure what the project cost I'll have a better idea on price.

If you look at the last picture there are 2 red High Temperature 3-ply Reinforced Silicone caps that will be used to block off the plenum

Okay well thanks for the teaser 😁 Please put me down on the list too.

Impressive to see the progress moving along.

Please keep us posted.

I would be interested in this as well if becomes available

Would this also work/be a good addition to my car even though it has an ess supercharger?

I feel supercharged cars would better benefit than NA just due to higher pressures

Then put me down if it shows to be beneficial and works seamlessly then I definitely want one

I haven't spent any time under the hood of my car, other than to look at the overall scene and go "oooh!", so I didn't know there was an SAP on the S65 motor. I remember those were on the E36, and SAP delete was a great initial mods, along with the M52 manifold swap and ASC delete. Why do you say its "essential for street application", and how difficult is it to delete?
