Timing chain

C

Hi all

At car has done 116000 miles and is missfiring. I've had it looked at, changed the coils, had a new cam shaft sensor fitted but its still missfiring. The mechanic said it could be the timing chain that has stretched and is a night mate of a job, so much so that people usually leave it and just let the car run till it dies .

Can any one shed any light on this and give me some advice. I only paid £250 for the car so is it really worth replacing the timing belt?

Thanks guys
 
Timing chains do stretch in the 1.5 and 1.8 petrols, common issue. Best to get quotes then decide if you're willing to spend the money. Once done though if the shell isn't too rusty it'll last you for a long time.

Not a nightmare at all. Will take a full day and should cost £250 + parts at most.
 
Thanks guys

Is it a job I could tackle myself of is it best left to a mechanic. It's not my main family car so if it takes me a while to do its not so important. I'm not a car mechanic but I do have a good mechanical back ground as I use to be a navel aircraft engineer. Is it just a case of replacing parts or would there have to be some timing setting up to do?

The body work on the car is pretty good. Got a rust spot on the front wing and a couple onset the rear window and it needs a bloody good polish but I recon its worth doing as I think it has got a good few years left in it
 
You can do a timing chain by yourself. The good thing is with the chain drive you can count links more easily than on the belt driven systems so its usually easier to time them up. I wouldn't tackle it without downloading the FSM though. You will need a new tensioner and chain for definite an maybe an idler (not sure on that). The new Nissan chains are improved items that are not as prone to stretch as the old type.
 
Bit harder on the N16 spook as you need an airline to spray down some stupid hole to lock the dephaser pulley. It's a French thing. I don't think your everyday tinkerer is going to work out how to do it. That part is a 2 man job too.
