M8NSTER = reading comprehension fail.

michaelrc51 it looks like they make a few, which STM tuned catch can do you have?

 

^Try trolling somewhere else, dumba$$.


First off, I know for a fact that can happen. Second, I'm only trying to help out.


Take your trolling bi tch a$$ out of here if you have nothing worth saying!

 

OK let's try that again.

 

Yes, cfdfireman1, lets read that again...


because there wasn't any line going from a vent to the air intake to create "vacuum" and pull air out of the motor


It says, "line going from a vent to the AIR INTAKE". It says nothing about a breather!


Breathers will vent out to the air (all STM cans I've seen have breathers). That can get sucked into the intake.


Again, I'm only trying to help. If I'm wrong who F'ing cares. Stop being a troll.

 

Talked to fp and they said it only takes one to two psi to move oil past the gas rings. They said to run a pcv and then drill an additional port in the vc, run those two ports to the catch can, then run the can to the inlet and to not vta.

Im going to try running a line to the inlet bc ****s already soaked in oil what does it matter. I really dont want to run the pcv and drill another hole in my vc

 

Mine is the 4 port firewall VTA one. I already stated it is VTA.

Yes, FP told me the same thing. Tell me how 4, - 6AN lines are even going to let .5 psi accumulate?

I will probably end up putting the line from the air intake to the valve cover just to see, even though it is VTA and shouldn't help......

 

had a similar prob with a better brand bb turbo , oil pressure was too high , oil restrictor fitted to feed , end of problem . forgot to say im feeding it from the cyl head .bb turbos require less oil pressure as you dont need to float the shaft like jb turbos

 

michaelrc51,
Question, did you install the filter with the .8mm (.030") restrictor from FP?

Please clarify for me and M8NSTER do you have any vent hose going to your intake pre-turbo with your current setup?

 

Yes, the restrictor is installed and no, there isn't a vent hose going to the intake pipe right now. But, I will most likely install a -6AN vent from the valve cover to the intake pipe and see if it helps....even though I don't see how it would....


This is the catch can I have

Is this minimal amount of seepage past the gas rings going to actually hurt anything? Is it going to blow the turbo eventually or can i just leave it as is and forget about it... Few of you have said you have the same thing, just curious how many miles youve ran it like that and if you are still on the same turbo.

Thanks for the help and input!

 

i refer you back to my first post on page one... I seriously doubt a turbo has ever been blown from an issue like this... but it will suck into your intake and cause detonation... which blows motors... i'm sure you aren't using a bb black in suck down 15psi... you are closer to 30... at 30psi the dynamic compression of a normal cylinder jumps to near 27:1... i highly suggest you vent the motor as best as possible...

like i said, hesitation, stumbling are big issues... plug fouling, misfire, detonation are more serious... and lowering the octane rating of your fuel is the biggest....

at idle pressures may be low but under boost your crank case pressure sky rocket if not kept in check.... check you PCV check valve to ensure its working... and make sure your breather setup is connected preturbo so it can vent under boost.

 

you guys running dbb, are you feeding the oil through the head or from using it from the bottom of the block? I have an FP Red DBB and I have the same issue I'm running a catch can VTA from STM and is setup like so, back of vc and balance shaft inspection breahter, and I have one line going to the intake and still getting oil. The guy above jospeh143 is my mechanic so I'll see him today and see what he has on mind to do it better.

 

Im running it exactly how fp says, from the oil filter housing with the inline filter kit. Using their lines too.


Imo, i think this sucks and im kind of pissed i paid so much money for a turbo with weak gas rings. No joke i had an ebay 20g on my wrx and never had this issue. Why would an fp, name brand uber expensive turbo do this but a cheap pos ebay knockoff turbo made in china not? Not hating just upset and looking for answers.

In the meantime im going to run my catch can exactly how they say even though i dont see how its making 1-2 psi, enough they say to push oil past rings, is possible being that i have a huge 2" breather port. It just doesnt make sense. Smh maybe im just stupid lol

If anyone with knowledge can fill the gap of retard in my brain that fails to understand this theory of building pressure when theres an open hole in the system, please fill me in. Thank you

 

Lol, same here.

People have told me it is normal but I still don't care for it and would like to alleviate this if possible.

 

There is an alternative that's been used in racing applications for years.
