DIY e46 secondary air pump check valve and vacuum line replacement.

[@stanleyplock1181]

The vacuum lines behind the Intake Manifold (where it's always hot) crack easily. They are really hard to access. Especially at the manifold vacuum ports. My 325i has them way back underneath the intake manifold. You can use a mirror to see the ports. And you can (with great difficulty) use an x-acto knife to remove the cracked hoses (2 of them) from the metal tube. But it's difficult to push the new vacuum line onto these ports. TRICK: I pushes a 12 " clothes hanger inside an 8" piece of vacuum hose. Aligned the hose into the center of the metal vacuum port line. Then slid the vacuum line down the clothes hanger and onto the metal port tube. The electrically controlled vacuum valve is difficult to unclip from the intake manifold. That hose cracks easily too.

thanks for the video dude another miami / west kendall homie here

Good job!!!! I have an E46 running a little rough 12mpg and low idle in drive replaced a lot already (plugs/coils/plug wire harness, fuel filter) so now Im thinking possible vac line, O2 sensor or fuel pump issue is going on. Tryna figure it out. Appreciate these diy vids. I replaced my front links bec of another vid so its cool what u can do on ur own with a little help. Appreciate ya!

[@JohnSmith-lu5rz]

I replaced mine it was stopping my emission monitors from being ready. Problem is it's time for a emission again and the same issue has occurred in time ? Could it be from carbon build up

[@jesusborrero3382]

I have 2005 BMW 325i the valve no have this lane

[@spuddemon7274]

Good procedure for removal, but I think somebody should mention: The secondary air pump and valve are part of the emissions system. They add air to the exhaust when necessary (cold start I have read) to make sure the catalytic converter can do its job. They cannot possibly cause rough idling. Also, on my E46 it wasn't 2 bolts; it was one bolt on the back side and a nut+stud on the front side. Everything is 10mm, which is convenient, even the windshield washer reservoir.

[@007DMW]

Its the vacuum line at the back of the manifold that cracks so intake manifold has undetermined air entering into manifold to cause misfire

[@martincasas1053]

Did you torque down the secondary air injection valve?

[@julianmcalister6865]

What codes did yours throw? I’m chasing a problem with mine. I replaced my fuel injectors and then after that, P1083, P0185, P0173, P0171 was thrown. There was a lot of carbon on the tips of the injectors and am wondering if it clogged this.

[@paulkranich]

So your diagram provided minute marker 3:27 does not show the black/white orientation of item#6. Item#7 which looks like the dry rotted piece you replaced as shown on minute marker 3:36 only shows the bad part as related to item#9 --can you say what direction the black/white check valved is oriented going toward the short version of #7 as it connects to the intake manifold? Also it would have been helpful if you could show an after repair complete picture or video. Just saying. My M52tu is a mess.

[@benjamingesserit]

Where’d you get that diagram?

[@jorarr5174]

Can this cause the car to stalled

[@richardwilber9463]

How do you know its clean ? shouldn't it be air free ,I tried blowing through it seems cloged still i put 2 cans brake fluid and carb cleaner let it soak ,if no carbon, should pas air easy right? Do you think i should just by new one?

[@Treyh4u]

Hey bro what the connectors on top of the fuel rail function I don’t have the rear one that secured on top of the fuel rail

[@lakerland24]

hey man i have question, that vacuum line that you replaced mine is completely ripped and thats why its throwing codes i want to know which is the exact vacuum line size and length because im finding them but the ones i see are short, and they say they go from the valve to the area you're speaking of but im trying to figure out how such a short line is going to reach that far. if you can help me and point me in the right direction that would be great thanks again!

[@flowmartinez7913]

The crazy part on your exaust there is another valve like this same size and the intake suction goes All the way to the exhaust to open a valve crazy ja?

[@pablitomontanez1131]

I have code p0492 secondary air system ....that the part i need replace right??

[@WhippperSnaperater]

It could be the valve, the air pump, or the vacuum line. I'd recommend replacing the valve, connector hose, and vacuum line first since the pump is much more expensive. If that doesn't work, then I'd try the pump

[@Captain-.James.-T.-Kirk]

Hi What codes did your car throw?

[@marcelopalacios3424]

Oyeeeee mi hermano! Did you have a check engine light on? Did it go away after you changed the line?

[@DriveMiami]

Yes it went away. Then the check engine light came on a week later over something else lol

[@marcelopalacios3424]

Drive Miami that’s BImmers for you.

[@TheLyfeofMarc]

Can you tell me where the black valve hose travels to and from?

[@isrealperez9069]

I don't understand could you tell me what's the difference between valve an EGR they do the exact same thing

[@johnsheikh3831]

I know this is 2 years old lol. But pretty much without the vacuum control switch. The egr would be open all the time because the vacum to the nipple would be present always. But because there is a vacuum switch it controls when to give egr nipple vacuum. Therefore controlling when the egr opens and closes.

[@frankryan8100]

I’m confused... you removed a part and put it back on. Not sure what you fixed?

[@gc4391]

Common vacuum leak on the 2004 and earlier cars. SAP vacuum solenoid, check valve and all hoses

[@jongkeunlee]

thx for video. So did you end up clean your check valve? And also in the diagram as vacuum goes around valve cover ther is a device at the back of the engine( there is rotation arrow on it) what is it? thx

[@mini_bmw455]

I think its called a electric or vacuum control valve, if im not mistaken.

[@luisgalvan9326]

What happend to the metal Gasket that goes in-between the valve and manifold? No wonder you're getting codes and bad mechanic advise.

[@buynow17]

did you have issue with air blowing out of the valve cover or oil filler cap

[@oakleyanderson4112]

a trick: you can watch movies at Flixzone. I've been using it for watching a lot of movies during the lockdown.

Good video bro my line is broken doesn’t even have one

U didn’t have that line, did u get any lean codes

Do you know the size of the line?

I like your videos I , I think your videos how cool. But I have read the comments from some of your videos. And They all act the same thing. I really think that you should stop rushing through your videos. more informative and pay very close attention to details. In one scene you are telling us what you're going to do. And in the next scene. it's completed That's not paying very close attention to detail. We ,the general public are not as smart as you are,.... When it comes to repairing our cars, That. we love so much. If we did not love Our card so much we would get rid of This piece of ship . We love, our Vehicles that's why we watch these videos. It would be more Easier for you to pay very close Attention to details to everything that you Post On a video so we can understand it.

[@pauliancu1368]

No code number, no examination of old hose for cracks, talk about winging it and throwing darts in the dark

[@t-wadeproductions5694]

Did you have any issues with smoke coming out exhaust?

[@nighttime1982ify]

Smoke is ccv valve change that and no more smoke

[@RobertWeir]

Very incomplete video .. what about the gasket ? And oh I just put a new vacuum line in .. it’s just so easy lol

[@anthonyharrell3733]

Control Valve...not check valve

[@DriveMiami]

Soap

[@illrichz]

@@DriveMiami Use about a teaspoon of sugar, a little water, and then wash your hands as normal. If it's a stubborn mix of grease and grime, you can also throw in some liquid dish soap. It works great, and it's a lot easier to keep around than a harsh degreaser and less gunky than cooking spray.👍👍👍
