SlickRick Posted May 3, 2017 Share Posted May 3, 2017 Took my car to nissan today for camshaft sensor (the other one went in October) and they changed it no problems. Then after they turned car back on eml came back on so they ran another diagnostic which said both sensors are now gone! Knowing that they can't be gone as they are both new, the mechanic believes that the timing chain is most likely stretched so the next step is to take the front end off and measure it and if it needs to be changed I should start saving up! I'm on 44k miles, my car isn't making any funny noise, took it to get diagnosed IMMEDIATELY after it showed same symptoms as when the other side went, there has actually never been any start issues, he also said that the aboslute max it should be is 11mil but I've just had look around online and seen people talking about 14-19mil at time of change? Need advice has anybody been through this or have any helpful input? Sent from my SM-G935F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stutopia Posted May 3, 2017 Share Posted May 3, 2017 Is there not an inspection plate on the front to observe the tensioner? I'm sure its extension can be checked to see if a chain is needed, before ripping the whole front off.

Edit: http://www.350z-uk.com/topic/77315-chain-tensioner/ This is why I think they have no idea what they are on about. I have zero rattle or even any extra noise, I've never had any start up issues, and they said to me the max the chain should be is 11mil but examples I find are all over 11mil? I've not even done 44k yet oil changes at 6month intervals... But my eml light is on so there must be something up and I can't be my two new camshaft sensors. I thought he was gonna tell me it's o2 senders cause of decats (even though I have spacers) Sent from my SM-G935F using Tapatalk Edited May 3, 2017 by SlickRick Quote Link to comment Share on other sites More sharing options...
Stutopia Posted May 3, 2017 Share Posted May 3, 2017 Get yourself off to one of the top places, Horsham, Abbey, Kaizer or Cougar Store, depending on where you are. 2 Quote Link to comment Share on other sites More sharing options...
Ekona Posted May 3, 2017 Share Posted May 3, 2017 First off, what are the codes? How many miles are you actually doing between oil changes? Not relevant to the issue I don't believe, more a case of I'd say you're changing far too early and wasting money unless you're tracking it loads or using particularly crap oil Quote Link to comment Share on other sites More sharing options...
SlickRick Posted May 3, 2017 Author Share Posted May 3, 2017 Their all pretty far from me South London. I'm booked in for a second uprev at Horsham next Friday Sent from my SM-G935F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ebized Posted May 3, 2017 Share Posted May 3, 2017 You are best off taking your car to a ZED specialist as Mugwump says, as the timing chains are very durable and with no odd noises I find the Nissan dealer's diagnosis hard to believe. Given you are off to Horsham Developments next Friday, let them give you an informed opinion - just ring to let them know beforehand so they can allow time and check the chain/sensors before the uprev. 3 Quote Link to comment Share on other sites More sharing options...

But they said the codes for bank 1 and 2 camshaft sensors. I'm pretty sure I'm changing the oil more regularly than is necessarily needed but I don't think that will cause the issue either.

ZMANALEX Posted May 3, 2017 Share Posted May 3, 2017 Was it genuine Nissan cam sensors that were fitted or did you supply them with aftermarket ? If the latter then that will probably be the issue. Quote Link to comment Share on other sites More sharing options...
