Turbo Oil Drain Do's and Don'ts. No More RTV! [Tech Tip Tuesday]

Turbo Feed and Drain Sizing, Components, and Details can be the most important factor in the lifespan, performance, and durability of a turbocharger.
In today's tech tip tuesday we talk about oil drains. While RTV silicone gasket maker has a wide variety of uses. We feel that it should be avoided when working with installing an oil drain flange. As you have seen in the video the rtv can dry and create a blockage from flow. Even worse those overhanging globs can come off and get into other places they shouldn't.
The simple principles of a turbo is that it needs high (ish) pressure oil in, and no restriction out. When a blockage happens on the outflow, the pressure needs to find a place to go. Because the engine still delivers copius amounts of oil, the oil tends to work its way out the shaft seals and into housings. This creates issues across the board. You do not want oil in your intake piping or intercooler, and you also do not want oil in your exhaust as it will ruin Wideband O2 sensors, create clouds of smoke that makes it look like Uncle Buck driving your race car, not to mention decrease turbo lifespan.
Gaskets are a usable option, however, in many cases the gaskets do not have the appropriate size hole and can also become a blockage. Additionally, when taking things apart, if you do not have another gasket this can become a frustration point. Plus they simply do not always seal the best.
Which leads us to our new high flow drain flanges with integrated high temp orings. There is enough crush area to equal great sealing across the board. Our funnel design allows for no blockages. To seat the O-ring we use a dove tail cutter which retains the Oring. This means that there are no worries about it coming apart and stretching when taking things apart, and also you can install easily on vehicle, and did we mention reuse it?

Doing my first turbo build, and I'm super inexperienced with this stuff. This cleared up the questions I had. Thanks. I too have boxers BTW 😅

[@whitneytay7633]

Well delivered and knowledgeable presentation. Not what I hit in my search engine😅 but glad I found this video. Very helpful, thanks!

[@knoxautophotography3422]

What if i purchased this flange and it still allows oil to come out..? getting to the point where im going to put RTV on this high tech flange because i cannot keep oil from pushing its way out from in between the turbo and the fitting. Frustrated as this is the 5th return line flange/configuration I've used without any luck stopping this issue.

[@Second-gear]

Very nice machined part, love that o-ring seal.

[@RC-fe9py]

I have this drain flange and it's completely AWESOME!

[@MODOORTEK]

Great information, well laid out, fantastic delivery. What a great resource in the performance field you are.

[@MotionRaceworksOfficial]

Ben w thank you! We appreciate your kind words

[@zachoryfitzgerald8259]

Just ordered my T4 flanges! Super excited to get them on the car to fix my smoking turbo!

[@amorag59]

Thought the dog shrunk in size before I saw both come into frame 😂

[@briacb6698]

I tried this return oil with o-ring and the leak is always here, no difference with paper gasket. any idea ?

[@guitargod66]

Nice vid. Just ordered one up! I have mine apart now and didn’t realize that I shouldn’t reuse the little paper gasket

[@jcyber2101]

Why would these be illegal for road use as mentioned on the sale page?

[@johnathonkelp3587]

I rub a thin layer of Honda bond on every oil drain gasket, let it dry completely and it'll never leak and you can reuse it.

[@camlobesvtec]

Looks like your dog is waiting for you

[@enlightenednews5265]

The dogs stole the show.

[@177SCmaro]

RTV is fine so long as you're not idiot about it. More is definitely not better. If people would just follow the instructions on the tube RTV works well as a sealant for a turbo drain however there are better options out there, as we see here.

[@nique_3036]

I personally use the rtv on drain gaskets and just like you mentioned if you apply it correctly everything should be fine.

[@user-gn3is5gs7v]

Asked about using this on the truck diesel and they had no idea how to help with it.

[@MrCostash]

You do 12an as well? Thanks

[@dexterbenjamin6054]

nissian np300 frontier pick up we installed a brand new turbo and passing oil at the back of the turbo where the exhaust manifold bolt on

[@st3v3harman]

very nice! I WISH all of them were like this. So stupid using a standard gasket for such a critical item.

[@bnastystuntz]

U make one for the garret gtx series??

[@half_r_mk5]

i'm trying to purchase this drain flange for my 5858, just now and your website is not working. Please advise. I can't seem to checkout. Thanks.

[@randybastyr1154]

Man I like your videos!

[@MotionRaceworksOfficial]

randy bastyr thanks sir!

[@donghunlee8620]

Is is possible to use copper spray at drain gasket? which is made with non-asbestos

[@chrisgroves7775]

I can name one turbo company that told me to use rtv on the drain which I refused to. They told me their surface was flat and the factory was not and also my aftermarket drain flange was not either. So I sent their turbo back and went with a better turbo company

[@GuyX2013]

Ordered the t3/t4 drain just now 🙃

[@aaronvanmeter7211]

Got a rear turbo drain line leaking is this important to replace ?

[@scottsingleton2655]

Another great video!! Dont understand why somebody would dislike this lol.

[@blackphillbuilt8382]

It was probably a handyman.

[@scottsingleton2655]

[@supercharged6771]

Great video

[@cumminscummins5684]

I believe Uncle Buck had a LTD. HA HA ,Love it

[@a.f.e]

Just purchased gunna give it a try

[@popanollie1]

did u use it? have a opinion?

[@sunwaterflowz]

Good job

[@JermaineLeeBlueprintAuto]

Is it normal for a garret turbo not to have an o ring on a compressor housing?

[@themechanic568]

Turbos done use o rings in the cartridge

[@richardsanchez4435]

Should I prime my engine after replacing the oil drain line?

[@jasonschreiber6458]

No

[@darinr9424]

Hehe uncle bucks wagon. Good one

[@randystingray6544]

Awesome video imo, could you link me a oil line feed also plz. T4

[@ieatass6463]

Lmao go find it yourself. So lazy

[@lilredrambler3205]

Oh. So this doesn’t go on my LLY turbo. Lol

[@TheUWNTSUM]

12 an version coming?

[@MotionRaceworksOfficial]

Rob Rohe we have a 12AN version for the large and mid frame. To run a 12an and fit in a small to mid frame it’ll have to be an extended length piece. We will be working on one for the near future

[@juusoperala1128]

Was this really just you trying to sell me that flange or were you actually trying to tell me about turbo oil drain, what about the engine side of the line, under oil line or over? Why not directly next to oil pickup... Not very informative video sorry, all i learned was that you really want me to buy that flange you yappin about.
