I HAVE A MAZDA REMAN WITH ONLY 1500 MILES ON IT , REBUILT TURBOS AND A DOWNPIPE . I USE EVANS EPG COOLENT AND HAVE HAD NO OVER HEATING. I HAVE NO AST . THE SMOKE IS GREYISH AND WHITE SOMETIMES , DOES NOT SMELL SWEET TO ME. SMELLS LIKE FUEL , I HAVE NOTICED A VERY SMALL AMOUNT OF COOLENT LOSS BUT I DUNNO WHAT WATERLESS COOLENT WOULD SMELL LIKE OR BURN LIKE (COLOR) .. PLEASE . NEED INPUT , THIS SHOULDNT BE HAPPENING ... IT WILL SMOKE WHEN FIRST STARTED COLD AND AFTER BEEING LEFT FOR AN HOUR OR SO ...

first, your caps are on

second, it sounds like that mazda reman sucks, try compression test it and tell us what comes back. also, how is your car running? how much vaccum are you pulling? how come you have no ast tank? what engine/car mods do you have?

I might be just running super rich or something. how much duty cycle is your engine getting at idle? did you replace the injectors lately?

Good luck

P.S. is there any warrenty on that engine?

KillerFD

no ast , im running waterless coolent no need to seperate air bubbles , i dont think a compression test will work cause their is zero pressures with this evans coolent. did recently replace the secondary injectors. i get excellent boost 10lbs. its idles at 700 -800 . i have a 12000 mile warrenty.. the car doesnt act weird , performs very well. except for that weird idling problem i get . that when i just poke the gas in nuetral and it will go up than drop down to 300 and almost stall than recover. i duno what the hell is going on

artguy

another example of someone with a mazda reman having problems!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

stop buying junk motors...


now that that is said....you need to do a compression check....not a pressure check...if you have a bad side seal or something then your compression will be down

do not drive it until it is figured out.

what ecu do you run? is your car stock?

welcome to the world of rotaries...cant go buying the cheap parts.

you get what you pay for.

the compression test will tell if its your side seals

pull the spark plugs...if there is any coolant on them then its an O ring problem

if its not that then its leaky *** turbos...let me guess..you got rebuilds????...oh you do....DOOD...you get what you pay for.

there are threads all over this board about NOT using the max remans and NOT getting turbos rebuilt.

you might get lucky...maybe there is something small causing your problemo....I hope that is the case...but regardless you went the cheap route and will be dealing with stuff like this from here on out...

where the sparkplugs replace recently?

I think you can do the coolant compression test even though you have a zero pressures system.

BTW: I was talking about an engine compression test.

I think its normal for a rotary to smoke a little when cold.

KillerFD

thanks guys i really do a appreciate your help ... cause i have no clue whats going on and its pretty freaken discouraging after all this work ... im going to do the compression test and check the plugs

A thought...

We're in autumn now. The air is a good bit more cold and dense. Wet as hell too. I'm noticing WAYY more condensation boil off when I start the motor now than I did even two weeks ago. Note that this is NORMAL for cars, but especially with our very hot cars. As the engine warms the pre-cats and then the cat, moisture will boil off. Further, shutting off the engine and the resultant cool down will cause fast condensation to form in the cats, which will boil off when started up again. So the deal is, near as I can tell, Start up the car: there should INITIALLY be no steam (or what you are referring to as smoke); after two minutes or so, LOTS of steam. This steam should be faily transparrent, and dissipate roughly three to five feet from the tail pipe. After the car has warmed up for roughly five to seven minutes, the steam should stop. The other types of "smoke" are oil burn (blue/black, smells like burning oil, looks like stupid Merc deisel. HATE those things... sorry!), coolant o-ring leaking (THICK white clouds of heavily sweet smelling smoke RIGHT AT STARTUP. Your plugs will be wet, and the smoke lingers up to twenty feet from the car) and rich burn smoke (blue, smells like gas). Where does yours fit these?

KillerFD

ill explain it like this at immediate start up it does not smoke it takes about 10 seconds for it to start comming out . it smells mostly like fuel and is grey in color but gets a little white sometimes.. it will last only a few minutes and than go away completley when the car is warm...but today it did this and i drove it to my buddies house . left it outside for less than 2 hours , came out and started it and it smoked for 20 freaken minutes !!, we were all like what the hell !! i gave up and just drove it home. car didnt act funny at all. my car is all stock except for downpipe and evans coolent conversion elimanating the ast . if i hit the gas it will blow smoke a good 6 ft and sprits of water come out .

spurvo

MAN it's late for you over there! I'm at a loss. I'm thinking you are running rich, but I must bow to those of more experience. The fuel smell makes me think rich, though. Have you looked at your plugs yet? They should be BLACK with carbon buildup if you are running that rich.

Hope it works, and someone else help this guy?

cournal

you have a motor problem,the smoke you are getting seems like coolant from the discription. maybe the evan's coolant used in this conversion just smells and burns a bit diffrently than the convetional coolant. remove the spark plugs and post a good picture of them.

cournal

another good point is the turbos, are they new or rebuilt? are they your turbos redone and how many miles on them? i have seen some crazy cracks inside the cast iron portion of the turbo units, but i don't think that would leak coolant just boost and exhaust.

rxrotary2_7

smoke is normal in a new motor. mazda remans are tested and run on propane pefore they are sent to sit on the shelf until someone buys it. i forget the name of what they use to keep everthign lubed in there for this "wait" of their life on the shelf.
have you ever put ATF down the carb of an old 12a that has been sitting just to hep you get compression and lube to get it started and not ruin everything? WOW that bitch smokes for a while... there are many new things that have to burn off. greases used, i know myself i use krazyglue to hold the 3 piece seals together during a rebuild. hell, it could even be your new downpipe burning off stuff inside.... i mean, there are a few things that could cause it.
i dont think that you should just assume your reman is bad. people have this conception of them that is wrong. i am not going ot go into a detailed explination, but try calling the plant in Jacksonville FL. i talked to them at length one time. the man i talked to said (this is paraphrased for shortness and lamens terms) there were a bunch of bad ones that went out over a matter of a few months. this was not a "mistake", but disgruntled employees building them TO BE BAD.

you still have not specified what COLOR the smoke is. this will help us help you in figuring out your problemo.

maybe i missed this, but how many miles and or hours have you put on this motor?

Nameless

When my coolant seals went .... well the whole week prior to it I had Evans being burned out of the exhaust, I didnt think it smelled like fuel. But it was white.

Smoke is normal in a new motor yes... but he says it's got 1500 miles on it, so I dont think thats it anymore.

KillerFD

turbos are rebuilt and have the same amount of miles 1500, went in when the engine went in ... i never had this smoke before only started at about 1100 miles ..the color is grey but also white i would say a mixture of the both somtimes more grey sometimes more white its weird and def smells like fuel...but who knows maybe this engine is freaked up and everything is no good ,,,

KillerFD

i just started my car and believe it or not it did not smoke . now this is weird but the exhuast did leave a little puddle that smelled like fuel and oil... im experiencing some coolent loss but its right under the hood where i smell tons of fuel and the sweet smell you guys are describing and my car almost stalls in nuetral at this point.

Is the hose still attached to the fuel pressure regulator? Take off Y pipe to the turbo do you see any oil on the sides? If you raised the car look for any places that seem to be leaking. Lastly, remains are getting better and better now that Mazda is no longer building there own remains, the plant has new ownership with better quality standards. A new engine will generate smoke and smell a little funny for up to about 2K or atleast that is what mine did; however, it sounds like you have a problem. Who did your teardown and rebuild of engine accessories?

sevenspeed in PA did the work

KillerFD

Alright i pulled the plugs and the were burnt to a crisp at the ends
they were not wett at all dry and burnt up !!!!

KillerFD

one more thing are both the plugs the same can put them back anyway or is their a dif i have one plug with a blue dot at the tip and the other doesnt have this distinction

skunks

the #9 sparkplug goes in the trailing (top sparkplug hole) and the #7 sparkplug goes in the leading. personnaly, i think you should switch out all four to #9's.

artguy

are your plugs black or white? or just clean?

no wetness suggests that it is not an O ring.

dont drive the car right now ok?

get it to a mechanic who knows the car.

KillerFD

plugs are white but at the tip they all burnt up like ashy ...im going to bring it to mazda tommorow ,normally i dont do dealerships but their is a guy their i know that knows this car very well...i think im just running super rich and thats what has created my smoke. i dunno im gonna find out .... ill report back . thanks again to everyone who took the time to help me you guys are awesome !!!!!! thank you

artguy

if plugs are white you are running lean.

time for dyno tune

I had a similar problem with greyish smoke for 10 minutes plus when I started my motor. Check your emissions. Mine were sky high. I had 2 hoses off under the intake in the rats nest which control emissions. With these back on the smoke went away and the emissions went back to normal. Mazda should be able to do both a compression and cooling system pressure test to rule the others out.

artguy

stay away from the dealer.

rotarytt if yer sending someone to the dealer you get a cyber smack!
