I think a valve fell into the engine. I though i heard a lifter ticking but passed it off as noisy valve train due to still being new. Today at 6000 rpms in 3rd gear the engine made a clunk and locked up. Im thinking a retainer broke and a valve fell in. Well time to see how good nissan is with thier warranty service, kind of sucks this is my 4th nissan and i never had to take one in for warranty work.

 

I take it up to redline almost everyday for 32,000 miles now, and I've yet to have an issue with the engine... Let us know what the stealership says.

^Same here, almost 32k miles now. I've auto-x'd it, tracked it, dragged it, no problems here. Runs like a champ.

Good luck.

 

Are u FI ????

Edit: Im sure ur not --- If u did drop --- It was a defect

 

Its 2006 with 6000 miles, im not putting a turbo on it untill i get around 30k miles on it to make sure i have no more retarded problems like this. Im so mad. When it does get a turbo it will be my own kit. I will weld all the piping and everything, pick up a utec, injectors and all that stuff used. I have already done flow calculations and picked a turbo heh. I also have an porsche 944 intercooler im saving, it was used in one of my other project cars and is good for about 550hp when i get the end tanks redone for 200$.

Is the 350z valvetrain not that good?

 

To my knowledge its great ---I redline every day @ 52,000 miles but this winter is motor build time and ---springs,rods,valves etc

 

Dealer tried to make me pay for towing untill i told him on the nissan website it says towing is part of the warranty to the nearest nissan dealership. I have a feeling this isnt going to go over very well.

 

If they try to BS you with "you were abusing the car" or "you were driving it too hard"

you need to make them put that in writing. ANYTHING they claim, they should put in writing.

That said, you don't admit to anything such as "I was going 6000RPM when the problem occurred"

All you need to say is "the car is broken and it's under warranty. Fix it please" How did it happen? YOU don't know. It's THEIR job to figure it out.

Good luck with getting your motor fixed. If your motor can fail at 6000rpm, it can just as easily fail at 3000rpm, 4000rpm, etc. 6000rpm is very safe, this is not your fault (unless you ran dry on oil or something.......)

 

Just a random question, how old are you?

Actually, I just realized it's an 06. When was your last oil change? I wonder if you really did run dry on oil...

 

I have mobil one in my car. I am 25 years old what does my age have to do with it? Its not dry on oil. Its still full of oil, i checked the oil after it happend.

 

A good rule of thumb.............when you have your vehicle towed into dealership always make absolutely sure all fluids [coolant, oil, AT/MT, diff, PS]are filled to 100%......and don't add while tow driver is watching as since dealership pays he will report what he sees.

The warranty REQUIRES you to maintain fluid levels to keep warranty in effect so that's the first thing that's checked.

 

Just askin. As I would expect something like this from a "16 year old that mommy and daddy bought the car" but yours sounds like something legit. Keep us updated. I've never heard/read of anything like this happening.

Well the tow truck picked it up. Its on the way to the dealer now. Yea i pay for my cars myself. I couldnt afford insurance on a sports car untill i turned 25. I should find out in the next few days what is going to happen. This is getting fixed under warranty one way or another.

 

If I have to add oil between changes, there is a problem. That oil BETTER be full or there is a consumption issue. I personally plan on taking my car to the dealer with low oil to show them "look, you guys did my oil change 4k miles ago and it's half gone already. I do understand the point you're trying to make however about not giving them anything to blame you for.

 

Well i called them today, they said the motor has seized up. Now im just waiting to see how long its going to be there. 6k miles a new motor, go me?

 

If u can get the info --and u have a right to the info. Let us know EXACTLY what happened in there. Very Curious

 

If you study the NOACK test for oils you will see that conventional oils can evaporate the lighter fractions anywhere from 11-15% of volume.

That means that 1/2>1 quart is normally evaporated up thru PCV system and burned in the 3750 miles.

There is no written standard for oil consumption, the warranty covers what Nissan says is normal not what you THINK is normal. Currently it appears they are replacing engines which use more than 1.0 quart per 1,000 miles.
Say your engine uses 1/2 quart per thousand and you don't do 3,750 mile changes you will sludge up and run empty of oil before the 7,500 interval.

If you run the engine low of oil by not checking and adding as needed you will not be in compliance with warranty.

 

Update - finally talked to the head guy in the tech department. Nissan requires them to tear down the old motor first to see what failed and if its cheaper to fix it. Should know in a few days what failed inside. He said i should be getting a new engine.

 

GREAT to hear !!!!! ( New Motor ! )--Stay on his butt cuz very curious what happened---Every Blown motor is like a book----A story to be told so long as the guy doing the tear down is a good "reader"
