i feel some type of rattle at 2k rpm like a lagg..

 

Did you try replacing the $15 PCV valve? If that gets stuck, crankcase pressure can cause evacuation of oil past the rings.

 

A G35 specialist just told me my sparkplugs are probably gone, i dont think they were ever replaced.. the car has about 94k

 

Mines just started to smoke a bit like this but its due to the new ART Test pipes i bought lol. Smells horrible but thats test pipes i use to leave massive trails of white smoke smelling like burnt oil but i don't even add but 1 quart of synthetic oil until3k which is normal cause synthetic oil does burn out quicker.Thing is test Pipes have oil in them used while being bent and so they won't rust while they sit.

 

That looks like smoke from warm moisture in the pipes + cold air

 

i just bought on 07 6spd with 29k miles on it and mine burns oil too... i can smell it when i get over 4k prms.. i have only driven it 2584 miles since i got it but i added a qrt of oil and had it changed the next day and only had at most 2 qrts in it... car goes to dealer thursday.. see what they say... im suppose to be under warranty til august 2011

but u can see white smoke coming from only my driver side exhaust on cold start and even after its warm but not all the time

 

You're not alone. There are numerous G and Z owners that have noticed the same exact thing after adding TPs and exhaust. They remove the TPs and the consumption stops. Do a Google search search for "oil consumptions and test pipes" and note how many Gdriver and my350z threads pop up. It sure seems to me like some VQ's have OC issues when you open up the exhaust significantly.

 

mine didnt stop when i took the TPS off. lol im on stock cats with MR ypipe and my single exhaust and it still smokes.....you see it in the vids.

and no (thescreensavers) def not moisture and it wasnt cold out.....the car ran for maybe a minute total before i washed it, that was after i washed it and dried it off. and the temps were in the high 40s that day.

 

Ok so i changed my pcv valve and spark plugs today. It feels like my motor feels likeit just came out the dealer..lol the smoke is gone..

 

i also had some oil in the 2 rear sparkplugs.. and the pcv valve
