The culprit is almost certainly the turbo seals on the K04, but feel free to correct me. The car drives fine otherwise, no issues other than that.
May I ask... for those who have run into this before...what is the best course of action, for the least amount of $$. /sigh.
Edit:
Maybe I should get a "DISI Turbo Oil Restrictor Bolt Kit" from JBR? $30. I confess that I don't understand how replacing a single bolt can help to prevent oil seeping past the seals.
The turbo is fed oil but gravity drains it...by putting in the restrictor bolt you feed less oil to the turbo so that it doesn't push past the seals. If you've had an otherwise fine turbo all this time, the restrictor bolt probably won't fix your problem...time for a new turbo. Good excuse to go little biggy (BNR S3, CS, etc) on your car.
You mean this little biggy? http://corksport.com/mazdaspeed-3-turbo-upgrade.htmlQuote:

If you've got that much positive crankcase pressure that your PCV system can't deal with it, then you probably have engine internal problems too lol Seals wear out though...how many km on your car? It's hard to say without checking some things out what it really is. Do a compression test, pull your intercooler and check for oil in the intake track, make sure your catch can is empty and not excessively filled with oil...do some leg work to narrow down what's happening.
96k right now. Catch can was cleaned last week, and only had a small amount of crap in it.Quote:

Or maybe this just means my K04 is facked and I need a new turbo.Quote:

I think if there was a serious problem with it they wouldn't make it, at least not JBR
Yeah, and it's also made by Damond Motorsports. Welp, looks like I'm going to get that ordered up tomorrow. Any thoughts on the Corksport turbo, Loki? I've been hearing good things about it on MSF, just wondered if you knew any more about it.Quote:

Yeah 1200 rpms is a bit high. Should be fine for the short term though. I havent heard of any negative impacts of the restrictor bolt. Install it and see, if anything your turbo is on its last legs so not much to lose. The CS turbo is a good little package and their turn around time should be better than BNR.Quote:

You do realize that the CS turbo is pretty well the same size right? In fact, the CS turbo claims to flow a bit more than even a 3071...Quote:

There isnt as much data on the CS turbo since its a fairly new turbo. The GTX28 is a more tried and tested route for sure.
Sure but it's also pricey and I have my doubts he's going to do e85/meth/built block or whatever else to really take advantage of more. I'm sure he'd be happy with a safe and pump gas 350whp tune and call it a day. So take the less expensive turbo that doesn't need any other mods (like 3" coupler or possibly new inlet), comes with all the gaskets and crap to install it, and call it a day.Quote:

I wouldn't buy corksport period
Their reputation on first runs has been pretty lousy as of late. Is that why?Quote:
