what else will cause this besides the pcv system? too much oil pressure to the turbo? what else?
okay a compression/leak test tomorrow. |

i'd be sorry too. i sure hope thats not the case. i can see that requiring the engine out.
if the rings didn't seat , can i pull the pistons and re-ring them or does this sometimes damage the cylinders? |

Unless you did something goofy with the hoses, you have classic symptoms of blowby past the rings. Compression and leakdown will tell you what's going on. |

How was the start up and break in? Did it fire right up or was there a lot of screwing around cranking and trying to get it running? Did you break it in with hard pulls letting off in gear to seat the rings? |

Was it over fueled at all? That usually kills a fresh motor nice and fast.

Sorry I blew up. I'm starting to think I don't have the patience for this e-tuning chit anymore. I was going to put a PDF together with pertinent info but I think it would be futile as people wouldn't read it anyway. Just imagine being asked the same question every day of the year.......then imagine 20 people a day doing it for a year. That's what it's like. |

Do the compression and leak down before you go nuts. If they come back ok then start looking at the oil pressure/ pcv routing.

I wouldn't say it started right up Jake. There was a fair amount of cranking to get it started. Don't forget it was started on bad gas and ran like crap for a while.

well my impression was that it started on first crank. it didn't start like a a new oem car but it started better than the first time 5 months ago. it idled rough due to bad gas but ran fine on four as soon as we replaced that. ron had not scaled the injectors or maf tabbed it at that point either. i feel like the car is running great. i think the tune needs smoothing out but i really doubt the motor is shot. i guess i could be wrong, but instaed of getting drug down into the land of pesimism which is where most of you seem to be, i'm going to remain in the land of optimism and run the gamet of test before i throw in the towel.
at the end of the day it isi what it is. no tears , no blame, just rebuild. its a toy. i'll be disappointed but i do have my family and my health so everything else will be okay. a new job would be nice! subaru mechanic in charge of breaking in new engines?

the problem is obviously blowby from the pcv sustem. the car is sucking a hell of a lot more from the 30r inlet than a stock application. i have a much bigger oil pump moving more volume of oil(not pressure). the pcv lines are kinda low on the block, making it easier for the increased vacuum under boost to draw oil to the turbo inlet. i need to loop them higher so that its not so easy for gravity to pull it down into the can.
if the pistons didn't seat or i washed out the cylinders it would not run very well and would smoke. the oil vapor in the turbo inlet is making its way into the intake manifold and at high boost lowering my octane and causing knock. its really very simple. not to mention my maf probally needs a cleaning...i know my air filter does. i'm going to plug the pcv valve and nipple off the turbo inlet. tie a line in from one valve cover to a tee at the crank case vent to the other valve cover to a can to drain into...simply venting the pressure. i will not lose metered air through this system. if there is a little oil, then so be it. if i fill the can then there may be other problems. the car starts right up, doesn't smoke and idles/runs fine. also there is a restrictor pill on the oil feed line into the 30r. |

^Why is it that almost EVERY built EJ seems to have problems?
Also, stop spending all this time rigging up your crankcase vent system and do a damn compression and leak down test to make sure everything is good first. Damn |

Lol. Why don't u just do a comp/leakdown test like everyone keeps telling you? You can do a comp test in like 20mins with a 20$ tool.

If I was Ron I'd definitely throw in the towel with an attitude like that...
Maxpowr, why not do some tests to see what the problem is first before you go and spend a ton of time and money to "fix" a problem that is probably caused by something else? As for your idea of "too much vacuum" in the turbo inlet for the stock setup- that isn't going to cause that much oil to be sucked up unless the baffling in the heads/crankcase is messed up or not even there. I a couple people making 400+ WHP on the "stock" crankcase system with no problems like this. Do your cylinder heads have 2 ports on them? |

i really don't have a bad attitude. i will do the compression test and leak test and reroute my pcv system. the v5 heads do have baffled pressure vents, but only one on each side. (2.0 ej207 heads)
why would ron throw in the towel? i hear what ron is saying though. i'm sure 90% of the cars phatbotti or any tuner is trying to tune have mechanical problems that need to get sorted before they can do their tune properly. we pulled the car, and discovered a problem. i will sort the problem ,which i believe is focused on the pcv bringing oil into the air charge, and get back to tuning. lets put the flame throwers away. i will do the compression check. i will do the leak down test. i will recalibrate the wideband. i will clean the maf, air filter, cai and top mount. i will reroute the pcv system. i will consult with my favorite tuner, ron , before making any more boost. |
