Hello All,
This is my first post, I recently own a 2004 Rx8 with smoke issues to rebuild it, I'm 23 yo & mechatronics engineer, so I hope make ths beaty run in ~3 months. First start

 

I cant see the smoke your talking about with all that fog

 

Cool,
Have you determined the problem?

 

Nope, I'm in process to remove engine

 

Cool man,
good luck. My high oil consumption and smoke issue leads me to believe i have bad oil control rings. So I've been watching a lot of YouTube videos on engine rebuilds turbos and what not. I figure I'd better familiarize myself with it now because I am eventually going to need a rebuild.

For what it's worth I was getting a p0661 intake valve voltage low or something like that. I cleaned all the oil out of my air pipe throttle body and air cleaner. I clean my maf and put a new o-ring on it, did some mods to the vacuum hoses that were already modded when I bought it. The hoses that are connected to the air pipe. That only helped my issue slightly but it didn't solve the smoking problem. I took out the ssv valve and cleaned it and its contacts, I changed the female contact. Car ran smoother with less smoking but still had smoking issues. Not as much though still significant.

The service manual said that one of the major causes of high oil consumption could be a vacuum leak. I wasn't able to find any serious leak so I attended to the other possible causes in the engine specifications shop manual. I did everything I could to avoid taking off the upper intake manifold.
When I finally did it I found that the vacuum leak was where the intake manifold double part, I don't recall what it's called, meets the two holes on the lower intake manifold. Basically there was smoke burns coming out of a lower part of the holes because the upper intake manifold was not bolted down properly. After cleaning out the solenoids and contacts and cleaning the upper intake manifold and lower intake manifold connections or whatever they're called, I have yet to get another p0661 or big burst of freaking smoke at a stoplight.

Apparently Murphy loves RX-8s because now my clutch pedal is s*** and I'm trying to bleed my clutch system. Besides my bracket being broken I have trouble shifting into gear when my car is on. It won't shift into gear at all when the car is on but will shift when the car is off. I bled it a few minutes ago but apparently I didn't do it properly because after driving for a quarter mile the clutch dropped to the floor and the car stalled out. I'm looking into the gravity bleed method right now. I also have to look about modding the bracket if that is at all possible.


Ah, l might need a master cylinder and a bracket... See some oil on a plastic bolt on the clutch bracket there...
