How The f**k Does This Happen (pic Inside)

[nuffsaid]

Ive had my gates for a long time now, still whirs. Not too fussed, the car has stood up to a heap of punishment, so if it aint broke i wont fix it hehe too scared to break things by loosening it.

[Bl4cK32]

mines got a slight whirr when hot or cold...comes and goes.

Been there since new, and im not fussed as i know its @ correct tension.

Some belts are just noisy...

[Adriano]

I would say without knowing the full story, thet the bolt holding the pulley on was dvertensioned. They are a hollow bolt, so they wouldn't be too strong.

Did you have the cams out?

If you did - did you make sure the cams could turn in the bearings by hand a bit each way reasonably easy(without belt on and hitting valves on pistons)

If the cam was binding up and the belt wont snap cause its good somethings gotta give!

Sorry to hear about it and hope you resolve it without too much expense!

sucks to be the people who said i f**ked it

heads fine as is the bottom end

no chips or cracks in the valves from what i can see

[MR331307]

i dont think its a belt problem

i had the same thing happen to my motor and it was due to High reving with the VVTI

a question for ya

are the cams standard

i had tommie pro cams

[paulr33]

chill out mate. In many cases it does. Internet diag. is a hit and miss affair and they are only giving advice.

[Rednisr31]

i was being sarcastic mate, no need to get riled up

and cams look to be standard

[gts-4 dreamer]

LUCKY BASTARD!

go buy a lotto ticket an share around ya schmuck!

hahaha

[Rednisr31]

has anyone else realised how retarded they are done

like, lets make it so you have to remove the WHOLE PLENUM to get at one bolt to get the head off

[fEkuaR]

easier to work on these cars with little jap hands

[Fitzpatrick Speed Works]

No belt should whir loud enough to hear it from inside the car driving, if yours does this it is TO TIGHT!!!!!

Sorry bout the failure you have there but diagnosing it from the internet is going to be really difficult. It could be anything from losing oil from front cam bearing which in turn snapped the camshaft, could be belt to tight, or as mentioned bolts could have been lose casue a slack that impacted a brittle part and snapped it.

Keep us all posted with pics, and what you find this is the first ever casue I have seen that isnt immediately obvious, and breaking this at all is pretty rare. Good luck pulling it down they are a bastard you need Japanese school girl hands, i swear nissan had midgets putting together GTR's.

[Guilt-Toy]

its not that hard! i did my head without any issues.. but then again i got computer geek hands lol

[T04GTR]

well the bolts meant to be done up to 123nm. unless a rattlegun was used i cant see how they could of stretxhed it

[Ryanrb25]

doesnt take much, im a toolmaker and from what ive seen even the very smallest of cracks in metal, hardly visible, over time with vibration will eventually let go.

[CefiroBoy]

Could the belt being to tight cause a big drop in power?????

I have a big dilema lol, had it all apart like three times checking all the timing marks were correct. So dont know what the problem is now!!

Cheers

Jay

bolt was either left loose, cam belt overtightened or the car may have had a front ender in the past.
