Mazdaspeed 3 PCV Removal! (without removing intake manifold)

today I went under the speed to try and tackle the pcv, this was a huge PAIN IN THE ASS ... it is definitely do-able but is tricky! ... i changed out the pcv valve on the crank case cover and will be installing it back in the car as well as my new Damond Motorsports OCC!

[@thomasd2695]

Mazda seems to go out of their way to make routine maintenance tasks hard af wtf

[@spoada]

Turbo journal bearing. You can take off your inlet to get to the turbo. You will see oil and be able to move the turbine slightly side to side but NOT forward and backward. When forward oil burns and it smokes. Let off the gas and it leaks. The pcv goes and takes the bearing with it.

Thanks. a million for showing how to get that plastic ring off. As far as the bottom up approach...it's good to know the alternative, but...this really looks tough too. And messy. I think I'll go with the topside repair. Either way it looks like I'm in for some busted knuckles.

[@RoadRoyals]

Glad i could help!

[@SrsLe33]

I used this method when i changed mine, phew was a PITA bc of the tight area, thx for the video

[@benjipelayo9366]

Sorry this is pretty old but did you ever find what was the problem with all that oil I got the same issue and I’m pretty sure my pcv valve is also messed up could that be the case?

[@MB-sp6sp]

Did you replace the plastic cover seal as well?

[@ncvman]

Did you clean the oil separator plastic before putting back? Did you get a new gasket for that or just used existing? Also wondering how much coolant leaked? What do you recommend to do to stop it from coming out? Attach a balloon to the end of it or wine cork? Separator - Mazda (L3K9-13-570) Separator Gasket - Mazda (LF01-10-2C8)

[@ncvman]

RoadRoyals thank you. Any special tools required? I will pick up a gallon of coolant. Now that you know what you are doing how long would it take you?

[@JuniorMason]

so did it fix the smoking problem?

[@ncvman]

Hi. Did you end up putting pcv back in from the bottom or by taking manifold off? Would this video apply to 2.3 Cx-7?

[@ncvman]

RoadRoyals I tried to do it today. Took me an hour just to get the dip stick out. F this. I will try from manifold removal or just let dealer do it. They estimate two hours. Peanuts for me.

[@bootsarmstrong8421]

I had '91 Mazda Protégé with the pcv on the valve cover. Now, with my 2008 Mazda 3, the pcv is buried, just like on your video. Why??????

[@yuritarded17]

What did you do to get the bolts off?

[@Tmoneygarage]

Hey man, where did you get the tow hook?

[@anaestereo810]

A like for innovation. Subd for perseverance.

[@forrestgrow1435]

I replaced that braided coolant line without removing the manifold and then realized my PCV hose had a rip in it :(

[@torek997]

Hi, I have a question, you removal this pcv becouse? I have cel P2187 fuel system too lean at idle in my speed6. I changed MAF, purge valve, and this check is still coming... what do you think, pcv removal could be help?

[@FernandoGonzalez84]

Did you ever figure it out? I'm getting the same code. I did a smoke test and it looks like it's the EGR valve.

[@mikef058]

I know this is a bit old but when replacing the PCV valve, does the black box have to be replaced? Does the black box have a gasket? What does the black box do?

[@mikef058]

@@RoadRoyals thanks for your quick reply. And the black box does not have a gasket or anything like that around it?

[@mikef058]

@@RoadRoyals got ya. Thanks for the info man. I do enjoy your videos, whenever I have time. Hope you do more videos of the black MS6 as well.

[@martyahad6391]

@@RoadRoyals The 'black box' is called an oil separator. Got that from the local Mazda dealer today when I picked up the new PCV (Mazda part #L325-13-890A, $36.26 Canada). There is a gasket shown as 10-23Y (not a Mazda part #) for the 'black box'. If I can't attach the drawing it is called 'Model/Year: Mazda 3, Section: 1370BB Emission Control System (2300CC). The circular clip that holds the PCV to the 'black box' is called a Retainer (Mazda part #LF01-10-509, $10.49 Canada). I think I will order the gasket and the retainer before I start this job.

[@martyahad6391]

Update Nov 8, 2019: The gasket for the ;black box' is a Mazda part #LF01-10-2C8, $17.45 Canada.

Take the dipstick tube out its one 8mm bolt, bit more room.

[@numinous4789]

Have any bad PCV symptoms? If so, what exactly?

[@JasonT._3568]

Excessive oil consumption ,possible lean codes (stuck open) blown seals (stuck closed) that is what I have found so far.

[@peterlee3825]

Hi can I remove the PCV hose and just install a mini filter on it? Don't want to let the dirty crankcase air into intake system and I believe this is the major source of carbon deposit on valve.

[@noahlehman1408]

You can remove the hose from the intake and cap it

[@VictorGarcia-gy8yv]

@@noahlehman1408 dont do that

[@noahlehman1408]

@@VictorGarcia-gy8yv I meant cap the intake and have it vent to the ground. Not the best for the earth but keeps engine from getting a lot of carbon buildup

[@VictorGarcia-gy8yv]

Hey did your car run rich because of this? Did it fix it?

[@salvadorlara9744]

Nah i know that. I'm tuned with BT but I have been been running rich...have no boost leak and I burn oil sometimes..thought it was valve seals but compression is good. Last resort would be this? SO fuckin lost

[@stevenwright3214]

Have you guys tried the bnoon, aka jbr restrictor bolt? it's a temporary fix but it really calmed the smoking on my car down and got me through emissions. I bought mine from jbr, definitely worth it until I can afford the new turbo. I also have a similar oil leak from the turbo and bought oil return gaskets but haven't installed them yet. hopefully that's the issue.

[@salvadorlara9744]

steven wright nah man I haven't tried that but I figured out my problem and I'm getting a lot of b blowby from my cylinders which could be from a valve stem seal leaking oil

[@RAMCO840]

RoadRoyals engine oil leak could be the engine coolant gasket, i bought the updated engine coolant made of metal and copper instead of just buying the gasket and using the cheap factory plastic engine coolant. common problem on mazdas.

[@TheGuruStud]

Delete PCV on every car, ESPECIALLY if DI.

[@tyronenur2373]

Good video, except for the cursing. This definitely is worth trying instead of intake removal.
