We need to talk about this oil in the turbo oil under the resonator oil in the intake oil tripping onto the alternator oil in the inner cooler oil oil oil oil You get the idea Nearly all mechanics just don't get this right in its costing spring owners thousands of dollars But what's really going on? Where's all this oil really coming from? Well? Whether it be a mechanic with 30 plus years of experience or even sometimes the dealerships They'll see oil in your turbo and they'll say that's a leaky turbo That'll be five grand to fix. Well, I'm here to tell you that that is simply not the case So the next time that you see oil in your turbo or at the top of your engine Just know that it can be fixed with one simple little piece But before I show you the best fix we need to break down what's really going on I'll be using the older spare engine just because it's so much easier to see what's going on But I'll also show you what it looks like on a new one as well as your engine runs a Small amount of exhaust escapes past the piston rings and it ends up building up in your main engine block Well, this is nothing new. It happens to all vehicles whether they're diesel or not The way most manufacturers deal with this is they have this little hose right here And this allows those tubes that escape past the piston seals to Essentially relieve the pressure from the main engine block. So nothing new about this You know it It happens in every vehicle old or new to some extent So this is the solution where say these came up with they just decided hey We're gonna take those fumes that build up in the blog and we're gonna put them right back in to the intake Now this works perfectly fine if you're just cruising along the freeway 6070 miles an hour that solution is going to work great now the problem comes in is when you're putting your engine under a very heavy load and The turbocharger right here is spooling up creating a vacuum all right So when that turbocharger spools Unfortunately that extra pull not only pulls the fumes out of the engine block But pulls the oil out of there as well and this is where the real problem comes in So when your turbo spools real hard when your van's under heavy load This hose right here is going to suck oil out of your engine like a straw and Once that oil comes out of your engine is gonna pull through the turbo and it's gonna get spit out all over the place You see some right here It's going to look like your engine is hemorrhaging oil. What's really happening? It's all coming from this hose now To be fair we're saying he's new this would happen And that's why they have this small little valve right here this small little round valve It has a rubber diaphragm inside which is vacuum actuated so when the turbo spools hard this valve closes and Doesn't allow any air or oil to be sucked through While the turbo spilling hard so That's what it's supposed to do unfortunately the rubber in this thing gets brittle about every Every 5200 thousand miles or every five years or so which causes it not to work so well So we still end up with oil getting sucked out of the engine like a straw when this turbo is spooling real quick Let's show you what this looks like on a 3.0 liter sprinter so this is the newer engine it's tougher to see this is the round little valve showing you in the other Scene and it has the same issue it sits on top of the engine it gets really hot the rubber gets brittle and it stops working So what's the solution? Well, you can replace this thing anyone can replace this thing as long as they know how to turn a wrench Might cost one or 200 bucks depending on if you want to go original or aftermarket But this isn't the most permanent solution because this thing stops working about every 100,000 miles So me personally, I just like to get rid of the damn thing. Let me show you what that looks like for just 17 bucks You get this kit right here. You essentially Align the engine block to breathe naturally so the fumes will just escape through this filter So engine breathes naturally intake is plugged off and your engine runs much cleaner This is how it looks installed Notice here this is how it used to be This circular thing right here is the valve and the hose ran from the valve straight back into the intake All we did was cut this hose right here. We allowed the engines blow by fumes to breathe out naturally intake side we used the little plug and while we're all set your engine is running better and there's no longer any There's no longer any oil getting pulled up out of your engine. I'll leave a link down below for this product Something I use quite often Now this is it the only way your turbo gets misdiagnosed. So if you're looking for If you're looking for other ways mechanics usually misdiagnosed your turbo I have a whole video on that here if you're looking for a way to save thousands of dollars on sprinter repairs. Well
