Symptoms included low grumbling noise from passanger side engine bay. After the lights (all of em) came on the car died on the side of the road. If the ECU thinks the cams are out of phase (bad sensor) the car won't start....safety feature.

okay got it... this ECU is very intrusive... in some ways a good thing... hopefully presented a code that made diagnosis straightforward

Sooooo...the crank sensor has a lot to do with timing advance/retard right? Or maybe running rich/lean?

I was at a Nissan "370 early owners" interview in Costa Mesa, CA--Nissan S. Cali headquarters a couple months ago. And coincidently, some guy there mentioned he had the same problem with his 370 after about 3,000 miles. If this happens to mine, it better occur either before 50,000 miles or 4 yrs. whichever occurs first. I don't like surprises, and this VQ engine is held up to some high expectations.

Nissan don't fail me, this is the first Nissan I've ever owned. :ugh2:

I will make sure we check the oil, sounds similar. Thanks Rick!

Well we are getting somewhere. Unfortantely I think it's going to be a new motor.
Here are the codes.

1. Cam Sensor
2. Crank Sensor

Replaced crank sensor - nothing, won't start
Pulled one crank sensor out- starts but won't go out of Fail Safe ( which means can't test anything past this, due to not thowing a code in Fail safe)

The fun part. So after Ricks post above we check oil.

Anybody want to guess how many quarts of Oil came out?

1?

2 Bob!

Winner Winner, Chicken Dinner!

Yep we pulled 1 quart. So we put in 5 /18 quart, let it idle for an 1 hour, and it burned 1/2 quart. So we drained the other 4 quarts and put a flashlight on it and it lit up like a christmas tree. So I may be getting new engine here. Might have to make some upgrades while the engine is out.

Still waiting to hear back from Nissan what the offical word is.... so till then

How many miles on the engine?

3000

Did you get a low oil warning before it shut down?

That is wild. I got a little freaked out and checked my dipstick last night... I'm about 3/4 of the way to "H." So I'm guessing I burned off a little since my last change, just don't know how much... I haven't read anything on how to read oil levels on this dipstick. *embarassed*

No and there is a built in code for that and light.

The same as Rick, very interesting and disturbing. Over 5k on mine.....

Let the car sit for atleast 20-30 minutes before checking. It sits right above an oil bypass(the dipstick)

It's just over 3000

I wonder if Nissan is going to try and bust balls over the mods you have.

If Rick's ate 4 quarts but did not need a replacement engine, I guess you had less ten 1 left...

oops, guess my reaction was a tad slow.. :-)

What mods?

Yeah, I let the car sit. I just want to know how I should interpret it. I/E if I'm 3/4 of the way between Low and High, how much should I add if I need to add any?

I'd be really interested in knowing how intake/exhaust can account for 1/2 a quart of oil/hour burnt... That and the lack of a low oil light make me quite suspicious.

I'll be going back to checking my oil regularly now...

Just read the online owner's manual and figured it out. :icon18:

There was oil coming out the exhuast, that's how bad it was burning oil. I have never seen this before, so it is interesting.

That is funky, lemon car??

I wonder if it could be blown valve stem seals? From what I know of the VVEL system - the entire valve cover fills with oil...if one of those valve stem seals goes, oil will dump straight into the combustion chamber, or, out the exhaust pipe...

1/2 quart an hour is pretty fast for blowby...

Did you see any "gas film" in the oil?


When was your car built / serial number? Could be a bad run of parts, might be worth noting in case...

So it does burn oil correct?

Have you changed your oil since you got your car or were you still on the factory fill?

Alright, new is New Long block, and heads. Whole lower end needs to be replaced. Yea! Time for headers

Yes, it's buring oil
Factory Fill
No Gas film, but the oil sparkles so pretty!

I guess I missed something - what's wrong w/ yours?

Bonus!......:tup:

Sounds like a seal (rear main seal)

oh snap!

Rear main seal would dump oil on the ground, not out the exhaust.

Yeah oil spitting out the exhaust. It idled for an hour and burnt half a quart. Check your oil!!!!! I can't believe it didn't throw a oil pressure light or code. That's what scares me.

I assume it's a warranty case, and not something you're getting special due to dealer relation (not insinuating, just making a point for the rest of us if this happens - I just kicked 1250 miles!)

Apparently the oil pump was pressuring things normally, hence no light as the sender thought all was fine and it would, right on up to the point where the oil to pump was depleted. Oil must be being sucked through a cylinder and out the exhaust. Catastrophic Valve stem seal failure?

??? At this point who knows, just wired that the computer didn't catch it in time. Oh well, time to start really messing with it.

Ok...so took the advice in this thread and check my oil lol....and this is what I found...

I did an oil change at 3700 miles to synthetic Redline.

Dipstick after change read as...

L o--------|------o H


Now at 6500 Miiles it reads...

L o--|------------o H



Seems normal to me....not sure how much the change in oil level (the two slashes) relates to in quarts but it doesn't seem like much. Looks normal right?

Edit: Fixed the spacing...had to add dashes...forum doesnt input spaces
