OK so before I get started telling you my problem let me tell you guys/gals what mods i have. from front to rear of car Ztube, JWT popcharger, Megan Test pipes, G coupe midpipe, HKS sport exhaust.
Now onto my problem i have had my Megan TP's installed on the car for about 2 months now and all was good CEL popped up 1 day after installing the TP's but I knew that the CEL popped up because of the TP's so I wasnt too worried. Now the car was smoking a tiny little bit but not like a Diesel truck and I had the smell of gas. Now On Tuesday I took my mother in law to the airport so I picked her up at her place and packed up my car I had 3 people sitting in the back and the trunk was packed with luggage. so upon leaving to the airport I scraped my Y pipe on a road bump now my car is smoking when Im stopped at a light and when I go to pull off it smokes but when Im driving there is no smoke coming from the car. Now I know that the VQ runs Rich so i was thinking of installing foulers so that first I can clear the CEL and second see if I can confuse the ECU to run a little leaner I need help. I have looked around but couldnt find a solid answer please help me

 

^Smoke color?

Also, have you tried simply resetting your ECU?

 

Color is a greyish or blueish color and yes I reset the ecu and still smokes Im gonna take my car to my brothers school on monday so he can see what the hell is going on with it could it be the O2 sensor took a crap I would hope not the car only has 64k on her

 

Ok so im planning on getting rebuilt heads for my car I just figuered if its a valve seal or from what I have been told a burnt valve and I gotta pull the head off the car I might as well rebuild it so im gonna buy one thats rebuilt. I have been looking at GTM motorsports heads and the stage 0 is pretty much in my price range. has anybody here dealt with them info please

 

sounds like you are just running real rich.

 

Blue smoke is oil. I would have a compression test done.

 

Yeah, you have probably been burning a bit of oil all along but now that you have no cat's it is becoming more apparent. I would also suggest a comp. test and monitor your oil levels.

 

Yea thats the first thing that im gonna do is a comprrssion test I know the car is burning oil cause I can smell it and after the car started smoking the next day I checked the oil and I was low the last oil change I did I used 5w30 and when i added 2 quarts I put in 10w30 and it wasnt smoking as much but still smoking now I was also thinking of using some lucas oil to see if that would help its a little embarrasing driving the car and having a puff of smoke leaving the car when I pull off a red lght some people will pull up next to me and tell me " hey,smoke is coming from your car" and I tell them "yea I know its cause I have no cats" then really embarrased I drive off but my car is an 04 is,it typical for this to happen to the 1st gen G35?

 

Do an oil change and switch to 10-40

 

^^^^ will this help with the smoke cause the oil is thicker?

 

If its bluish white smoke then youre buring oil. +1000 on doing a compression test. I went through this 2 years ago and ended up replacing my engine. Keep an eye on your oil levels as its really easy to get low on oil when its constantly burning. Boa sorte!

 

Pepper obrigado well now that im working again its really hard for me to be able to take my car to get looked at cause I dont get home till like 7:00-8:00 pm which sucks but bills have to get paid. I might just have my brother take my car to his school to get the comp test done
