Timing chain spec v

Post by **atiffarooqi** » Sun Jul 16, 2006 10:05 am

so ive been hearing this rattling near the front end of the enhaust and today my engine service light went on. so im on my way to autozone to check it when i hear a fluttering noise coming whenever igive gas and the nmy engine died. i am assuming this is the timing belt/chain since the gas was being given to the engine wihle the fluttering was going one but slowly the engine died, so im thinking the timing slowly got off course. now my question is this, is my car gone forever? i heard somoene say once the chain is gone its good bye to your car. i still have me powertrain warranty. the thing is also that for a while as the engine would warm up for a while when i drive any thime i press the gas a rattling noise would come, but my dad said to ignore it, now im thinking it was the chain. the rattling i refer to here is similar to the sound of a baby rattle rolling on the floor, a continuous rattle, if you know wha t i mean. the rattling i heard yesterday sounded liek i loose plate or bracket. i hope all isnt lost. i tried starting the car again and the rpms dont move a bit, so this further leads me to believe that its the timing.

Its either the timing chain or you have spun a rod bearing, which has the telll tale signs that you mentioned. Rattling sound during idle and increases with the RPM's. Eventually there will be complete failure as the motor looses compression. If it's under warranty, I wouldn't worry at all. You will end up getting a new motor. Have you checked the oil lately? The early model 02 spec v's had an oil consumption issue, just as the new ones do also.

DMAN! a new motor?! thats crazy, seems pretty drastic btu why not if its free haha. I heard nissan usually covers powertrain for 5 years/60,000 miles. is that true?

Nevermind i found out it doesnt. but i have an ext warranty so im good i hope. it kind of sucks though i wanted to at least witness the work. thatd be cool if they let me keep the engine for a gift or something. i could play around with it. I never would have guessed it was a rod bearing, i dont een know what that is! But i guess now i will. anyway, we shall see what the verdict is.

Well, it turns out i need a new motor. i hope the warranty covers it since i had an accident almost a year ago. is there any negative side to gettign a new motor, other than having ot break it in again?

Post by **RED_DET** » Wed Jul 19, 2006 5:41 pm

Was it timing chain or rod bearing failure? Only down side to new motor is break in period and the fact you don't know if its going to be reliable until you put some miles on it.

New motor, negative? No. Resale values suck anyway, so no harm done, in fact you might get more in the case of a Spec V.

congrats on the new motor man, treat it well, it should last you a while.

Post by **atiffarooqi** » Thu Jul 20, 2006 4:26 am

Thanks on the congrats, i never thought i would get a congrats for it haha. but i dont know if they will do it under warranty yet, i had an accident in october, so i dont know if theyll void the warranty on this repair or not. im extremely nervous. but they didnt say what exactly the problem was yet.

So it turns out that the catalytic converter started to shred and get sucked into the engine. Some parts of it got pulled into the engine pipe, so they replaced the engine and the engine pipe. What i would liek to know is how it happened and how the cat can move from exhaust to engine if engine air is flowing out. Could it have happened due to my driving or is it just luck of the draw? The guy said keep it under 60 for 1000 miles, do you guys have any other tips for the engines healthy break-in?

Pre-Cat failure has been a serious problem since the introduction of the Spec V. Although some owners don't think its that big of a deal. Just drive it nice and simple for the first 1k miles. Don't drive at one consistent speed either for a long period of time. Obviously the precat failure can happen again, so most owners opt to put a aftermarket header on, which is about the only way you are guaranteed that this doesn't happen again. It's a bit retarded that you would have to mod a car to keep it from blowing up, but it's your choice.

Post by **atiffarooqi** » Wed Jul 26, 2006 3:01 pm

See now i could tell my dad that and hed flip. Im lucky he isnt selling the car. So i guess im just going ot have to pray every time i drive.

Actually now that i think, i remember a lot of peopel on forums teling me to get an aftermarket header immediately.

Interesting news. so my left speakers failed when i got he car back. i took it o the shop and they gave it back to the guy who did the engine. I sat with him while he too kthe car for a test run, and it turns out im driving a time bomb on wheels. he didnt even diagnose anything hes just like replace it. hes worked on so many SE-Rs that he doesnt even need to look at it. i was amazed. he basically told me the power is there but the car doesnt last liek nissans are known to. He also told me my shocks are bad, now i cant identify that since i dont kn ow what good/bad shocks sound like. but he basically told me warranty will cover it so no problem, but i should complain about it next time i go in to pick up the radio. even for the radio its free b/c we own so many nissans we're good will customers. just something to share.

Actually, now that i think about it, i have been hearing this weird noise for a while fro mthe throttle, but onyl whilet he car is warming up. im thinking to just bring that up too.

Driving a time bomb on wheels?

Replace what?

The car lasts just fine if you take some preventative measures - header or gutted precat and loctited butterfly screws - certainly things you shouldn't have to do to any car, but calling it a "time bomb on wheels" is a bit much. Some cars do just fine with the stock cat and nothing done to the butterflies.

I have no clue how your shocks could be shot unless you drive some horrible roads and/or over speed bumps way too fast.

What sort of "weird noise?"

Post by **atiffarooqi** » Sat Jul 29, 2006 11:42 am

yeah i guess time bomb on wheels was a bit much but the guy was bashing my car os much i was liek wow theres a lot wrong with this car. I guess i just didnt expect it fro ma sentra seeing as how we have had nissans forever and thisis the first time weve gone throug hsomething this ddrastic. I would like to gut my precat but i wouldnt be allowed to, seeing as how my dad wont let me touch the car at all, even for its betterment. I assume the loctite screws are for the intake manifold b/c i heard something about it becoming loose. I drive usually on city roads to there tend to be construction zones and unpavved roads a lot. the weird noise im referring to is every time i press the throttle half way or more, theres this crumpling sound. i guess, as weird as this analogy is, the closest thing i could compare it to is the sound of cicadas in the summer. it goes away after a while but still makes me uneasy. This is something else ive been encountering, some cal it juice clutch, but i dont know if its that. the clutch sometimes loses its pressure and i cant tell if it engages funny or not, since the pedal feels so weird. one guy said i might need a master slave rebuild, and i dont know what that entails or what that would cost. i tried lookin it up and apparently there are master and slave cylinders in the cluthc mechanism, but im not sure what they do, or how to rebuild them.

Wow, that's a lot of possibly problems on such a young car.

It almost seems that you've got a lemon, most Specs are fine beyond the precat and butterfly issues.

A dealer should be willing to loctite your butterfly screws for free.

Have someone check the clutch, you shouldn't lose pressure like that. These clutches are hydraulic, so the master and slave cylinders have to do with the hydraulic fluid. There's no reason you should need a rebuild at this point in time.

Without hearing this "crumpling" sound, I can't be of much service on it.

What I can say is that unless you beat the hell out of this car, you've got a particularly strange Spec.

Well, i did have a pretty serious accident in october 05. The sound came up after the accident. the sound dpesnt affect the performance at all. its just something bothering me. And i did buy the car used. the guy who sold it seemed extremely honest to the point that i dont think anyone could pin anytihng bad on this guy but you never know what he mght have done. And in terms of beating the car i occasionally pushed the car, but by pushing i mean i would shift at 4-4.5, i rarely redline. i dont stall, i dotn burn the clutch ever. other than that its driven normally. Im thinking its just luck of the draw. But since the precat is a common thing, and the sound is most probably linked to the accident, someone told me that the loose clutch could be the expanding of the cable, since it mostly happens in the heat.

i also tend to be very picky so i may make small things look liek big problemsplus the dealer said i should expect problem after problem, for instance when the speakers went out, the tech knew automatically that i needed a new radio. Almost liek thats a common thing he sees. so the fact that he talked so lowly about the car made me not think that the car is a lemon.But if it is anyone wanna lend me some money for a Z? haha Modified by atiffarooqi at 8:55 PM 7/29/2006

A serious accident will make a car finicky, now it makes sense.

Post by **atiffarooqi** » Sun Jul 30, 2006 11:42 am

Yeah, but at this point as long as the dealer is willing to cover as much as i can get covered, im good. Im just glad the car is running normally, but if they can fix these minor issues, why not? so well see next week weh n igo in for the radio. So stay tuned! (no pun intended)

Hey I feel your pain... I've got a 2002 SEr SpecV and I've gone through every common problem with the SER SpecV. I've had a butterfly valve screw fall into the engine, causing all kinds od trouble...New fuel pump at 50k, weather stripping on doors changed twice (leaks), warped discs after only 30k, fan speed selector board replaced, and last but not least the cat went and that resulted in a new engine...just before the warranty expired...I now have a problem with the new engine... usually while driving at highway speeds the check engine comes on and starts flashing.. within a minute or so the car starts to lose power and stall... pulling over and turning the car off and on again solves the problem... no code is stored in the computer.... so everytime i go to the dealer they can't find what's wrong...of course this problem never occurs with the mechanic in the car.... anybody know what it could be?

Post by **nametakennow** » Wed Aug 02, 2006 7:05 pm

The ECU is going into safe mode. Without an OBDII reader trying to pull codes right as the flashing starts I don't think you're going to have an ounce of luck. Maybe give it to the dealer and make them give you a loaner car til they can get it to screw around on them.
