I babied my car and I still got consumption. :(

I'm glad your engine is doing well, but if it were driving styles only, Nissan wouldn't have released a TSB pertaining to a specific vin range possibly experiencing issues.

That's usually related to either an identified defect in a part or the building process. My money would be on a part (valve seals, rings), but who knows for sure.

Thats lame! My 1995 300zx didnt burn any oil! 210k miles and no problems, I really miss that engine :(

With the type of consumption that Avantgti7 is seeing, would you notice large amounts of smoke out of the tailpipes and soot on the bumper?

Not necessarily - mine was using a quart every 2500 miles, and no smoke from tailpipe; no soot (although soot is usually a too-rich fuel problem, not oil). Engine probably burned the oil very efficiently.

New engine replaced under warranty behaves the exact same, in every way except the oil level NEVER varies between oil changes.

--ZOM

In reality these engines are not supposed to burn oil. The early vq37 do have oil consumption issues due to a manufacturing defect in the piston rings. (Since yours is 09 that is you) Same issue as the early vq35's. If you are under warranty Nissan should replace your shortblock.

Did they do short or long?


Tapatalk2 ...

Nissan is only doing shortblocks now. Our 3.7 heads are in the neighborhood of 6kish.

I can say that I had very bad soot on my oil burning engine- the cool thing is that you could tell what side of the engine had the problem has one tailpipe would soot up as opposed to both (true dual exhaust setup).

No smoke.

After the engine change, the soot disappeared.

In my opinion, black soot on the tailpipes accumulating over 1k miles should be considered a warning sign of possible oil consumption. The pipes will get dirty, especially with test pipes, but just a heads up .

What if you have a muffler delete (aam short tales)? Would you get some darkness on the tailpipes?

Kinda like when you run hi-flow cats, you would have some smoke when you get on it.

You shouldn't get any MORE discoloration than normal with short tails.
You'll always have SOME soot with cats, just not half as much as with HFCs or TPs

Kinda thought that, thanx for clearing the air.

:tiphat: yep, I just put my cats back in, LOL

Here is an update guys...

The new short block from Japan arrived to my dealer last Tuesday (03/26/13). They said it would take two days to put it into the car and provided me with a 2013 Altima 2.5 as a rental. On Thursday afternoon, I called the dealer only to find out that the tech just finished installing the motor. My service advisor said the tech was not happy because it took him three days to put the motor in and Nissan's warranty would only pay for two days. My advisor went on to say that the tech would bring him into the shop periodically to show him how much labor was involved and that he should be paid for more than 16 hours of labor. Finally, my advisor said they were test driving the car now and that they needed more time. He said not to come in without calling. I said "okay" and hung up the phone but I had this uneasy feeling in my stomach.

On Friday morning, I decided to just stop by the dealer and see how things were going. I wanted to see if I could catch the tech test driving my car around or he/she pulling it in/out of the garage. I didn't see anything but I had a face-to-face conversation with my service advisor who said that the car's engine was not running right and having timing issues. He said they would need more time and to keep driving the rental car.

On Monday morning (04/01/2013), the service advisor called me to say that the engine still was not running correctly in my car because of timing issues and that they needed more time. Today (04/02/2013), I called my service advisor again to hear the same thing about the engine not running correctly because of timing issues. He said that he would call me back tomorrow or Thursday about the car and that it should be done by then.

Everything is being covered by warranty but I am worried because a job that was suppose to take two days has taken more than week now with hiccups. Will keep you guys posted.

Bad install caused by an inexperienced tech, IMO. Don't settle for anything less than perfect with this engine. They have a step-by-step to follow with a breakdown of how much time is expected per process which adds up to the overall hourly total which Nissan reimburses.

Give them as much time as they need to get it right, but stay in touch with the service advisor. The rental is on their dime, so don't sweat it.

The car should not throw codes, hesitate on acceleration, or do anything out of the ordinary. Don't accept the car if it exhibits any symptoms whatsoever.

:iagree:
