Burning Oil - BAD - 1 quart every 200 miles
I've got an 03 G35 with a single turbo on it. I'm roughly adding a quart of oil every 200 miles or so. There is no oil dripping down under the car, or anything smoking from the engine bay as far as a leak.
I did the compression and leak down tests and both numbers came back great with all compression #'s above 180 and the highest cylinder % of a leak was 9.5%.
I checked my intercooler tubing coming off of the turbo and there is no oil in the tubes so my valves seals can't be gone.
What could it be? Anything? I can see lots of smoke in my exhaust, the classic bluish gray when driving, and an initial start up of a bit whiter (I believe its cause of too much fuel on my idle tune - getting fixed soon) Coolant level is still high, so it shouldn't be the head gasket.
My oil pressure never goes about 70psi when in boost, and at cruise sits around 40psi.. 10-20 at idle.
Could it be that I need an oil restrictor feeding the turbo? Could it be the turbo oil drain isn't working right and its burning up oil in the turbo?
No ideas....I was still getting 350 whp at the wheels so if it was my engine burning it, wouldn't i notice a bad power loss if I was going through that much oil.
I do get the smell of burnt oil when decellerating sometime, but I guess thats expected.
Any thoughts would be great, as it really sucks having a s**t ton of smoke coming out when I'm hard on the gas, or off the gas at WOT, and there is a bit of smoke too when any type of extra load is added.
Don't want to have to hit up IPP for a new engine.... Thanks
