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.
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?
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.
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)
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?
@@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.
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?
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.
@@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
@@noahlehman1408 my bad I thought you said to cap the hose coming from the PCV, yeah it's not ideal but planet earth is not going to pay your mechanic bills either
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
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.
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
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.

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?

Hey man, where did you get the tow hook?
Did you replace the plastic cover seal as well?

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?
A like for innovation. Subd for perseverance.
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??????
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?
@@RoadRoyals thanks for your quick reply. And the black box does not have a gasket or anything like that around it?
@@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 thanks for those numbaz.
I replaced that braided coolant line without removing the manifold and then realized my PCV hose had a rip in it :(

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

You can remove the hose from the intake and cap it
@@noahlehman1408 dont do that

@@VictorGarcia-gy8yv yeah should've specified lol
so did it fix the smoking problem?
Have any bad PCV symptoms? If so, what exactly?
Excessive oil consumption ,possible lean codes (stuck open) blown seals (stuck closed) that is what I have found so far.
Hey did your car run rich because of this? Did it fix it?

Working on the fucking speed AGAIN xD
Delete PCV on every car, ESPECIALLY if DI.
Won’t pass emissions
Good video, except for the cursing.
This definitely is worth trying instead of intake removal.
Swearing is mandatory when you're a DIY mechanic lol
I am really starting to hate this engine.
That's too bad, it's been nothing but good to me!
I love my speed but the circle jerk of "it's easy to mod and make power" is utter bs lol. You gotta spend a bit to not fuck it up
@@RoadRoyals wait, once you have to fix shit it is one thing after another and none of it is easy.
@@Dyl_Camideally you can make 340hp and 390lbft with £800 of mods, just need decat intake hpfp fmic and a tune
@@MUSA-o5kYea I realized you don't need that much later lol I was super mad at the car when I commented that 😂
the dubstep in the background is unnecessary
Perhaps it was for the listening enjoyment of RoadRoyals, that alone made it necessary. IMHO
What did you do to get the bolts off?
