They don't remove 100% of the blowby from the system, nor will they ever separate 100% of the air and oil. No company has ever claimed that they will. People believe this is what they do and it's simply not true. The only way to completely eliminate it is to not return any of the vapor back to the system...such as a catch can. This is why all AOS will produce some 'sludge'...even though some produce less than others. I think we just have to agree to disagree on this one. Was not trying to start an AOS war. What i would really like to know is if you guys think that the introduction of E85 changes the way the blowby behaves in the AOS? |

I know and I agree with most of what you say squidz and I do not want to beat the AOS thing into the ground.
Lets looks at it this way. If you have an AOS system that does not work well and like some of us on here feel the filler top units have inherent faults (they are too small and you're venting from the valve covers/ heads and expecting the AOS to drain the supposedly collected oil back into the same space) that which allow them to be overwhelmed by BB gases. So now you are pushing it hard creating blow by and crankcase air/ gas pressure, then you slow down or dial it back to cruising or slow down to idle. Now you have vacuum and the PCV kicks in and starts venting. It starts pulling the oil saturated gasses into the intake below the throttle body. We all know that's not good, oil in the intake lowers the octane level of the combustible gas which we all know. I really believe that the stock PCV system was designed for stock power levels and emissions regulations. Once you are beyond those power levels then I believe there are way better options to vent crankcase gasses and its best to then rework the whole system. I'm sure your motor is tight and working well so you are not realizing the limitations of the PCV systems you are using but eventually you will! JMHO Last edited by manitou; 03-04-2013 at 07:24 PM. |

Actually... Oil blowby lowering octane may just be another hearsay internet rumor that no one I've ever heard of can legitimately verify. If you step back and do not assume it is true, I would like to hear a case supporting it (seriously, I would like a non hearsay argument for it and against it).

you gotta be doing something to bend rods like that. excessive timing, maybe some hard hot laps....bad tank of fuel to much cylinder pressure from something!

What do you tuners on here say about oil in the intake tract? Does it lower octane rating on the AF mixture? Has this been proven?

Ouch! That's got to be some bad pre-detonation to wrinkle a rod like that!

I doubt it was debt if he was running e98.
Remember those graphs of cylinder pressure? All he needed was too much timing and even without detonation the cylinder pressures would exceed the capacity of the rod. Ethanol burns quicker than fuel, so if he was aggressive on the timing he'd have an explosion occurring at a fast rate while he was still adding energy with compression as the piston moved upwards. Cylinder pressures at TDC and just after would be immense. |

e85+ too much advance =
which means this Totally sucks man to waste a nice Carillo Rod. Those rods are pretty darn sweet. |

Here is a little fea on a connecting rod. This is supposed to be compression forces.
This one is what rpm does. Notice the direction of wrist pin flex (and how exaggerated it is) I stole these from google images, but I recognize them as being relatively accurate. |

i am finally making my step up to e85 in a month. already made the appointment, not going for huge numbers, car only has a 3" DP, nameless 4" mufflers. adding FIC 1100s, DW65 fuel pump and having installed at my tuners shop. dont like the fact my current etune has my injectors 100%. do i need to add an intake, i hear the newer cars are good for 350whp but there are so many conflicts...

Little beat but not horrible. Worse than I would expect from under 3k miles.
Only map he has. This is from the old e70 tune that spun a rod bearing and bent all the wrist pins at around 4k miles. Timing was increased for the e98 tune but I don't know by how much. The aem has been sent back to get checked. Idle timing is strange Important to note that this is a hybrid engine with oem gasket and Cnc head chambers. Not sure of cr.

wow.
There is your answer right there. You bent all the wrist pins and your tuner thought it was a good idea to add more timing? That timing curve is ridiculous. You should have 5-7 degrees less timing than you do in the 20.76psi area (at LEAST). Last edited by Maxwell Power; 03-05-2013 at 07:05 PM. |

I don't know how much was added but it was a different engine and fuel this time. It did have a weird issue where it would misfire or break up at full boost pretty often.

even from 14 psi on thats still alot of timing imo. rather make the power with boost then timing.
