what else can it be? Someone told me it could be my oil metering pump. Can someone tell me how to do that mod?

 

I'm having the same problem but I never touched the turbo's. I have a 94 (California emmissions) RX7. Everytime the car sits until cool (usually only when it sits over night) I will start it up and It will pour out smoke enough that you can't even see the car... Once you drive the car around the block and kick the turbo's in it will go away. So now I am forced to get in the car and the second I start it I have to race around the block (which is terrible for a car just warming up) Now I have my check engine light on and I did the diagnostic test and got code #16 which is the EGR valve (only on the California RX7's) My coolant light is also coming on and off and i see that around the coolant sensor there is a leak The only modification done to this car is the AST removal. (i don't think this leak or the AST removal has anything to do with the smoking problem) WHAT SHOULD I DO????

 

Maybe your motor is just getting tired RedTT. How many miles do you have on the motor? Later, CJ

 

A little smoking is okay (less than 30 sec). Also, is the smoke white or light blue. It would be old motor (worn seal, blue smoke), bad water pump seal (white smoke), or running rich (blue or dark brown smoke).

 

I have 89K miles. It starts up and smokes to the point where I can't even see out of my back window. Then it calms down but doesn't go all away until I drive off. The motor could be too old but it still pulls strong, I just ran a 12.88 at the strip on saturday with a huge boost leak

 

Have you tried disconnecting the OMP? If it IS injecting TOO much oil at start up, it will, obviously, cause you to see the cloud of smoke at startup.

Smell the smoke, and tell us if it smells like antifreeze or oil :p

 

Redtt I am having the same problem... I have a LARGE amount of smoke on start but My car seems to start and drive just fine.. It seems like if I accelerate quickly the smoke will go away sooner. Like I said it only smokes when it is fully cooled down like when I get up in the morning it will do this only the first time I start it that day. <--- I don't think that it is the Oil Metering Pump if it is only doing this the first time each day? As for the smoke I believe it is white and I haven't heard the one about the bad water pump seal yet. I am leaking coolant from where the coolant sensor threads in!? Please HELP ME and keep me informed of what you find out!

 

how do I do this? Can you explain to me what the omp looks like and how to disconect it? It 's blue smoke and smells like oil

thanks

 

The OMP is on the front left section of the engine. I gotta see exactly where the connector is to make sure you don't disconnect the wrong wire, but if you DO find it, ONLY disconnect it at start up. You can't leave it disconnected while driving because the OMP is used to lubricate the apex seals. You would kill the engine if you leave it off while driving.

 

Another solution would be to disconnect the metering oil pump permanently and go with a 2 cycle oil mix in your gasoline... It lubricates your apex seals and does so even better than the pump at full boost as the compression causes the oil to back up in the lines. This is what race rotaries do and it is better on the engine. Just get some AMSoil 100:1 2 cycle oil and add 8 oz to every fill up.

 

Flybye, can you please let me know where the connnector is? I'm smoking like crazy!! If worst comes to worst I'll just disconnect it permanently and use premix. Please someone show me where it's at

 

Dood, I'm at work, and tonight is the First show of Enterprise!

Gimme me till tonight at least!!

 

cool, thanks for your help

 

Most of the time the smoke is coming from worn out turbos. The oil leaks by the oil seals over the course of the night and is pooled up in the housing on start up. It burns off after a few mins when your oil pressure goes back down to normal pressures and the oil pooled up is burnt off. Even a rebuilt set of turbos can do this. Rebuilt turbos are not new turbos. They replace the oil seals but the wear inside can still cause blow by. You can't replace the worn metal so the tolerance between the oil seal and the housings is larger than when new but the size of the oil seal is the same. Understand? Rebuilds are usually a quick fix and are never as good as a new set. Hitachi turbos are not totally rebuildable in comparison to what a normal turbo is.

 

Ok, lets start with test Number one.....

Look at the front of the engine. You will see an oil line coming out of the turbos and into the front housing. Right ABOVE that line is the oil metering pump. Simply look for its harness, disconnect it, start the engine and let it run for a few seconds and see if it smokes. Don't let it run too long unless you are running premix.

Actually, here is what you SHOULD do.....
Premix about 10oz of oil with a full tank of gas the day before. That way, when the morning comes around and you disconnect the pump, you wont have to worry about the engine since you will have oil with the fuel.

 

are you talking about the metal line? That would be the oil inlet line right?

 

OK the harness to disconnect is blue in color? That's the only one I see. I'm going to start my car back up at 5pm so please let me know

thanks

 

Sorry! Been busy all day long. I hope you didn't disconnect the oil lines. You'd make a nasty mess. The WIRING harness to the pump is what you should try disconnecting.

 

OK, are you talking about the inlet or outlet oil lines? There are 3 oil lines. Two is put together with 2 10mm nuts. The other is an actual oil line that you have to take off with a wrench. If you are talking about the one that you have to take off with a wrench, I only see a blue connector that goes to the EGR. OK, upper or lower oil line? What does the pump look like? Sorry for all the questions but I would hate to make my car a garage patato.

 

No no.

Don't disconnect the oil lines. Disconnect the wiring harness from the oil metering pump!

Maybe you shouldn't try it

 

I'd offer pics, but I'm hardly ever home during the day

The reason why I am suggesting this is because with the stock ECU and straight through exhaust, I'd get a lot of blue smoke in the morning. With the Power FC, it toned it done. The Power FC only controls certain funtions of the OMP, for some odd reason, but it was enough to not allow it to smoke like mad in the morning.

 

Dude, I know not to take an oil line out. You mentioned that the harness to unplug is by an oil line so I'm just trying to figure out which you are talking about cause I see no harness by any oil lines. Only harness I see is the one for the EGR valve
