Car still smoking an insane amount... help please
 

Okay. I posted here a few weeks ago to try and get an idea of what to look for when I dug into my car as to why it smokes an assload upon startup, until its warmed up. I removed the uim and checked the spark plugs (replaced all of them today) and performed a compression test. 3 even bounces of 95psi and 3 even bounces of 94psi, which according to banzai is good :icon_tup:
I talked to a fellow FD owner I know here and he said his FD did the exact same thing when his turbos were shot. my car hasnt been boosting for a month and I took the time to listen to all the different toots and whistles while under the hood and opening the throttle, when the rpms start to drop back down I can clearly hear what sounds exactly like a turbine spinning off center, like a bad bearing or messed up blades. not only that, but there is smoke coming from where my turbos are at. another thing I noticed today is, I removed my radiator cap part way (to let it vent) it sprayed over a bit from the pressure... but I was able to stick my finger in the neck and the water wasnt even warm. it was cool to the touch, THAT makes me thing I have bad seals and the pressure is getting into my coolant. but im not 100% sure but.... any help would be appreciated.:scratch: :scratch:

Does it smoke when you come to a stop or after WOT? If so it most likely is the turbos... Also is teh smoke blue? Is it sweet smelling white smoke?

Blueish = Oil = Turbos
White = Coolant = Coolant Seal

check your intercooler piping, if there is a lot of oil buildup in there then you've got a bad seal on the turbos, giving too much blow by

but the no boost issue should be a dead give away

when you checked your coolant was the car warmed up? even if you had a bad seal in the turbos, they wouldn't make your engine/coolant any cooler

its actually white....


=[

does it produce the smoke constantly or just upon startup?

blue smoke doesnt necessarily mean turbos...

my rear oil control rings went, and my smoked like crazy at start up. My turbos were brand new, less than 1000 miles on them. Remans straight from Mazda.

it smokes until its warmed up, and then it will smoke once I let off the throttle the 1st time I go above like 5krpm. after that it stops.

does anyone know a site that sells turbo rebuild kits? or.. (im posting a new thread im impatient for a link) but yea guys, please keep the advice coming i reallly need it. haha

the oil metering injectors can have the check valve inside fail as well. under boost the car will push oil through the vacuum hose which in stock form is connected to the turbo inlet. then the oil will be pushed through the turbo, intercooler, piping and then burned through the engine. it will give the appearance of a turbo seal. The way you test the check valves in the oil injectors is by trying to suck air back through them, if you can they are bad. u should only be able to blow through, not suck.

agreed

ok, I replaced the plugs 2 days ago, went to start it today and it hardly smoked at all...... seriously. wtf. at this point in time id rather the motor just blow so I know whats wrong and can fix it.. do the lower spark plug wires matter which plug they go to (thats somewhat stupid) when I start my car it makes a really funky noise and stops, my guess would be the plug wires are switched ? but im not sure. its just white smoke, atleast according to my eye. someone else said its blue. what else should I be looking for here? I wanna crash it into a freaking tree.

Does the smoke smell sweet? Have you checked your coolant levels to make sure they arent going down?

If its white smoke, it will look like someone turned your RX7 into a fogger, and it will continue to get worse until the coolant seal finally goes. You'll know when its done, because it wont turn over anymore (cause its hydrolocked from the coolant in the chambers...lol).

Also, with white smoke, theres nothing really bad about it, your car should run like normal (aside from the smoke), other than its a death sentence for the engine. It may happen today, tomorrow, 3 months from now...but it will eventually go.

If it is in fact the oil control rings, then the motor would have to be rebuilt to fix it. I just recently had this problem with another car after replacing the turbos 3 times trying to figure it out.

i think ill just take a video and post it on youtube. ill update later. thx guys

will a compression test help prove the oil control ring is bad? any other test?

the oil rings wont effect compression, so no a comp test wont prove anything.

As the engine heats up and the engine expands from the heat, it will close up the gap at the oil control rings and it will stop smoking, simple as that. It will be pretty obvious tho, the car will smoke like crazy at warm up, but once its warmed up it wont any longer, so any smoke you see after the car is fully warmed up is going to be turbo problems.

When my oil rings went, id smoke out my TOWN with oil smoke so it was BAD.

mine quit when i changed plugs. now my idle is fucked...
