I was in the market for a vehicle, I wa searching 8k and under. Looking at a lot of cobalts and other things I thought to myself... Hmm for 8k or less I can something a lot sportier then some fwd supercharged pos... Well my buddy had a rx8 a few years back and I loved how it drove. Needless to say two days ago I bought my first rx8 with 88k on body and a little over 20k on engine and transmission replaced under warranty by Mazda.

Today I decided I would check the air filter and the spark plugs.

First thing I found was oil in the intake... Thank god I made my own oil catch can at work a few months back...





I made the catch can pretty long so I installed it on the only spot I could fit Her for now. So for now she is mounted on the air box, which isn't too bad because the engine cover hides it.



As you can see I bought her pretty dirty under the hood.



Next thing I did was remove the sound dividers and install a aftermarket filter inplace of the horn since my stock filter was trashed anyway...

Then I pulled the spark plugs and found that both the lead and trailing spark plugs were carboned up pretty bad. When shinning a light into the rotor housing I could see that the rotor too had some build up...



I pulled the dip stick and saw she was about a quart low and according to some crap hole oil place sticker it was already at 3300 miles sice last oil change. So changed the oil and filter while I was at it.

After I let her warm up I noticed my crap idle no longer existed. I took it around the block to open her up and hopefully clear some carbon out. A few times it started miss firing In the real high revvs. A couple times later I have noticed that it cleared up. Thinking there is a lot of **** too burn off in there based off what I have seen.

Anyone have any recommendations on how I can clean her out faster without causing any damage???

 

Hi !! Srry for late reply but just found out this site lol. Congrats on your purchase ! Rx8 are awesome cars!! I made the same fix as you did and built myself a catch can, fixed the issue. As for your spark plugs carbon built up, put new ones in first and then check em' out after ''normal'' usage. If the ex-owner used to drive it like a grandma ''always at low rpms'' and let ran it on idle like crazy, carbon built up is normal especially on these engines, Stock fuel mapping on em' are on the rich side to start with. If your new plugs are still ''average'' clean after a while you can always do a quick seafoam treatment, but personally i'd do it really slowly with our engine configuration.
As for the crap on your oil stick, was it white kinda foam crap ? if so don't worry about it, it's condensation from the venting, usual stuff.
As for the missing quart of oil well get used to it it's normal, you'll have to add about 1L about every 1k mile.
Your images are marked as ''bad link'' so i couldn't see em' .. i'd like to see what you consider a big carn built up on the rotors, used rotors usually are more carbonized then pistons are on a otto cycle engine.
