Smoking out the exhaust
#22
Wow, that first post is exactly word for word the same problems I am having right now. My current solution is:
...and to replace valve seals, headgasket, and rings. I just don't understand how this happens all of a sudden. That sucks dude, I know exactly how you feel

Have you checked your plugs to determine which cylinders are leaking oil? Also I can't find your spark map...

Chaning the oil AFAIK is going to affect viscosity a tiny bit. Dirty stuff will be more 'gloopy'. That a technical term you ********, so lay off
The thinner new oil might be going past turbo seals/ring/valve seals more. If I knew any real specific **** about restrictors I would probably be saying +1 to the restrictor idea, but I dont so I wont. But it might be consistent with the fact that changing the oil affects it so much.
And I guess I say this in every damned thread, but that does not mean I am wrong. Comp test. At least then you have the peace of mind of knowing your rings are not shot.

the 35* **** is a little wack, but this is mine at 8.6:1 4*behind MBT (no detonation limit anywhere)
I've never tuned a 1.6 or seen a spark table from a respectable individual, but I don't think his spark table is unsafe. Where are his det-cans?

Vash is making over 250rwhp, running 20* of spark on his stock 1.6L at +12psi. I suggested this day would come, but I was shrugged off. "It is what it is" what does the know? who am I to know?

Is his car 9.4:1 or 9.0?
Playschool Dynojet or a proper adult dyno? Tone down your disrespect.
I stand corrected. However smaller cylinder bores allow for more spark advance due to some weird volumetric math **** that I don't understand but that's the logic behind motorcycles running 15:1 compression ratios with 30* of advance at 100kpa...but I bet piston speed has something to do with that too.
