Wow, that first post is exactly word for word the same problems I am having right now. My current solution is:
Attachment 198861 ...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 Head gasket repair (AGAIN) - MX-5 Miata Forum Have you checked your plugs to determine which cylinders are leaking oil? Also I can't find your spark map... |
if you're going to tear it apart. DO IT RIGHT and build it broham:)

Chaning the oil AFAIK is going to affect viscosity a tiny bit. Dirty stuff will be more 'gloopy'. That a technical term you assholes, so lay off ;)
The thinner new oil might be going past turbo seals/ring/valve seals more. If I knew any real specific shit 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. |

Link to spark table?
A quick look at the pistons will tell you if the motor is dead or if its the turbo. I suggest a bore-scope with lots of resolution. |

the 35* shit is a little wack, but this is mine at 8.6:1 4*behind MBT (no detonation limit anywhere)
http://i33.tinypic.com/1zaydu.jpg 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 :brain: know? who am I to know?
|
Also consider that making the same amount of power on a 1.6L requires higher cylinder pressures than a 1.8L, making the knock threshold lower.

At 9.4:1cr on pump gas, I'd call that a bit unsafe.

You mofo's have some crazy fucking ignition maps. Holy shit:eek5:
20* at peak boost? 34+ in various other areas? WOWW |
