So starting like a couple days ago, i started having very rough start.

I've known about the updated starter, and i've planned on installing the upgraded starter when summer rolls around, i don't think it's the underlying problem, but having a weak problem is not helping it either.

Basic facts:
2004 Manual.
75k miles.
Plugs changed at 42k, and recently at 72k
Oil changed every 3-5k miles, 10W30
Differential/Transmission oil flushed at 72k
Premix 4oz per full tank Idemitsu
Old starter
Coils and Wires changed at 42k

Codes Thrown:
P2070 - Intake Valve Stuck Open bank 1, thanks to jon's videos, i've confirmed the problem to be SSV valve, slightly sticky, but not stuck, do not believe it to be a main problem.

P0300 - Random Cylinder Misfire Detected

P0302 - "Cylinder" 2 misfire

Symptoms:
When starting the car, the car struggles very hard to start, once started, engine feels like it's flooded, and the whole car/engine shakes badly along with very weak idle. I would then rev up a couple times to 4k-5k, and hear the familiar purging of gas from my exhaust, but much much more (on cold starts, i saw a ton of white smoke coming out the exhaust, much more than normal). After purging the engine, the car's idle returns to normal, no more smoke, everything is fine and normal at operating temperature.

I often had to top of radiator fluid (every couple months), i am suspecting there is a leak somewhere causing the white smokes? (i am gonna do a smell test next time.. though i think the white smoke from start up is oil, it ain't sweet smelling) I did hear fluids flowing which i suspect is coolant when i had the rough idle, not sure if i am suppose to be able to hear it flowing.

What I've done:
Checked Air filter, cleared
Check MAF sensor, needs to be cleaned, it's all nice and black.
Checked VDI, moves freely, http://www.vimeo.com/5353829
Checked SSV, slightly sticky, summer project planned, http://www.vimeo.com/5353829

Currently out of town for interview so no easy access to tools, gonna probably drive back once i am done and check the following.

coils, wires, plugs.

Solution:

Anyone have any inputs on what may be causing the ultra rough idle and the misfire at idle/flood?

white smoke is never oil. white smoke is always water/coolant. if you got a bunch then you have coolant in the combustion chambers. that means you have a seal leaking which means the engine needs rebuilt/replaced.

ya, i did a smell test, when i saw it this time, it's semi sweet, it's coolant, i think i am looking at an engine rebuild indeed... would this be covered under engine warranty? cause if not i am just gonna find time and do it myself somehow, gota clean the SSV valves anyway.

bump, anyone know if that is good enough to get a new engine? or does it have to die before they'd act?

just in case anyone end up on this thread searching, the car was brought to the dealer. approved for new engine.

confirmed on burning coolant and evidently i also have low compression on rotor one i believe, will try and request the whole report when i pick up my rental.
