This is the route that I have, with the ONLY different that my can is vented and there is a check valve between the vent and the can itself. Is there anything I can add to help or assist the ringlands? Best way to check/diagnose those? I ordered a new PCV valve.

Raider I ordered a new PCV valve. Aside from taking the intake manifold off, any quicker way of getting to it? That intake is a massive pain the ass.

Good morning. Been trying to figure out lately what is causing my excessive crankcase pressure. So much so, that the gen 2 valve cover breather took a vacation and it blew out almost a quart of oil. I have an oil vented oil catch can that has remained empty for 5k miles. Hoses are clean, no...

The log I posted should have the MAF voltage. That log was taken during said event.

Recently cleaned the MAF, visual inspection of wires seem intact. Further testing suggestions to determine wiring or sensor ?

Hey all, having some issues at idle. I’m attaching a log for reference at idle. Year/Make/Model: 2007 Mazdaspeed 3 Mileage: 122,xxx Location: Jacksonville, Florida Concern: At idle, intermittently the car will lean out, AFR goes wonky and the STFT will go wonky up to 24.8. While driving it...

Rgr. I will do that.

Awafrican Looks as if the smoking issue has been resolved. After much discussion and consideration. I pulled all of my charge pipes, cleaned thoroughly with parts cleaner and washed out the Intercooler. Additionally, I’d like to thank Cfoldone for the email that he posted from BNR...

Stephen Mcneill Awafrican I’m interested in this as well. I’m having similar issues with idle. I have smoke tested and pressure tested the entire system, but I am having intermittent issues at idle. AFR will blip up and down as well as STFT. I’m going to attach a log for review. But, I have...

Man, if it’s not one thing it’s another. Oil dripping from the hot side of turbo from that bottom corner bolt. There shouldn’t be oil there…

I was hoping to catch it soon enough to avoid that by upgrading to the JmF manifold

Cfoldone pulled my restrictor bolt and it’s measuring approximately .066”-.068”… I wonder if I can open that up just a hair Cylinder 3 compression though was 210psi?

Awafrican Enti this is my catch can setup. Pictures aren’t that great. But PCV to can, from can to intake. The line from can to intake manifold has check valve point to the intake. I took it apart to check it all out and there was milky oil from the can in the line to the intake, passed the...

No sir. The OE manifold was relatively clean from what I can remember. I’m currently at the shop doing some work. I have the intake pipe off and the inlet side of the turbo is dry and clean. No sign of oil.

Surely hope not because that would void the warranty and when I last spoke with Brian a while back about the turbo, I had told him I had a restrictor bolt from DM on it and he said it was fine.

Noted! [emoji1787][emoji23]single best response to-date. Thank you for the laugh. I’ll be in touch!

Rgr. I will do just that. Additionally, there is a check valve in the VTA line before the filter. I made sure of that as not to introduce a vacuum leak. Only excess crank pressure exits, nothing is pulled in. How should I guesstimate the amount coming from the PCV? Video and post? Mtnbker3531...

I ran the same oil restrictor bolt that I had bought for the K04 when I acquired the car, just used new crush washers that were provided with the s4. Additionally, I’ll get my TDC kit before I head out tomorrow and do a cylinder leak down test tomorrow and post the results for you, just to rule...

No, I had acquired the car and it was tuned by Freektune. I had reached out via email and Facebook to get any information about the car, but never got a response. The previous owner was, well, I’ll be nice..he didn’t know much about it. So, my first actions were compression, cylinder leak down...
