Downpipe And Our Horrible Stock Turbo Seals

[J-Villa]

nytmar3, seems you are talking to a wall in some of these posts.

If you are afraid of smoking, get a damn catch can. Small investment for a worthy cause.

and you can't trust all horror stories also b/c every car is different and this may seem like a shock to some of ya'll.... but mazda does put out defects. \



Where you @ in jax nytmar3?

But Jax is only like 20 minutes from here.

these seal horror stories remind me stories about rx8 rotary engine that the will last only to 80k and engines are blowing like crazy......funny s***

Here's a better question, why all the stories of people's cars still smoking after getting a turbo covered under warranty?

Here is an even better question:

Exactly which part of the PCV system is responsible for the smoking problem?

here is my post from another board.

Well i installed my catch can and here are some pics i took after it was installed. sorry they are after but when i start working on something i hate to stop and take pics. this was all done without removing the intake manifold.

i orderd an oem pcv valve from mazmart on the 6club forum. it cost me $10+ shipping. one side of the valve is orange and one side is green. you want the orange side attached to the catch can. basically if you blow through it you want the airflow to go towards the intake manifold. this is because when you are in boost you don't pressurize the catch can forcing oil back up into the crank case.

stock PCV > catch can inlet

catch can outlet > additional PCV (oriented so that air can only flow from the catch can to the manifold) > intake manifold

parts needed:
-1 Catch Can (Saikou Michi w/ baffle and 5/8" ports)
-5ft of 5/8" heater hose (should be able to hold up under vacuum without collapsing)
-1 oem pcv valve
-1 5/8" to 5/8" heater hose adapter
-clamps

i removed one of the horns and used that as my mounting location. rather than replacing the hose from the pcv off the engine i just used a 5/8" to 5/8" heater hose adapter so i could add on to it without having to try and fish around in there. i figure if the stock hose was good enough all this time no use tearing it out.

i then had to cut a section of the radiator support out so i could run the hose.

i then attached that to the inlet on the catch can temporarily and then also temporaily ran the hose down from the top of the engine bay and connected it to the intake manifold.

i then started the car up and poured some seafoam directly into that hose so it would go in through the manifold where all the oil was traveling so it would get cleaned up. let her sit for 5 min then started her up and smoked up my neighborhood for 5minutes.

after that was done i took the hose off the intake mani and then begun routing everything nicely. i cut a 2" length of hose and put it off the intake manifold and then hooked the second pcv valve up to that. i then attached the rest of the hose which would lead to the catch can. after all was hooked up and clamped i started her up and checked for leaks. couldn't find any so all is good. buttoned her back up and well keep everyone posted if this resolves my smoking at idle, which i'm pretty sure it will.

this is laying under the car looking up behind the intake manifold. to the passenger side of the oil filter.

3,000 or so on 3.5 TM, tubes, forge, cs tbe, and original mscai + notune. still running a bit rich. No oil loss or oil smoke. rec'd in May 07 ordered in Feb. 21,000 and strong like bull.

Nevermind, I just read up on the g37 a little and those mods I mentioned would most likely just make it a race. Yeah you might need that DP lol!

I could shift at 7600rpm in my G37, but it's also a 3600lb car. It doesn't quite have the hmmph bottom end like the speed 3, but once you start hitting closer to redline it'll throw you back. I have a few local friends that still have a Speed 3 and I'll run them on a closed course and see what happens.

Cool! Keeps us updated and congrats on your new ride!

I think im just gonna go ahead and do it.. where can I find those OEM pcv valve?

I had 0 mods done and my car was smoking at idle as well. Took it into the dealer, they had the car over night and "ran various tests" and said I needed a new turbo as well. They ordered the parts I dropped off the car again, 3 days later I got the car back and 500 miles later still haven't seen smoke.

Do you think in my case, being it was completely stock and mine was smoking it was in fact a bad turbo? I was thinking about ordering a GHL exhaust and a test pipe, but if it's going to smoke again, i'd rather not.

Also, will a test pipe make me fail inspection?

Where do you live? The test pipe will most likley make you fail inspection.. depends on where you live but Im in the same boat as you. I would also like to buy the CP-E test pipe and catch can but im a little nervous for a smoking problem too but so far everyone with the similar mods have not had a problem.

its possible, some guys on here put down 350+ on the stock turbo, i dont know if they got them reworked (cant remember)
