When to replace the Timing Chain?

[Mjforan89]

Hi

 

Tomorrow Im going to look at two different zeds, really looking forward to it. One has 93K miles on the clock, the other 115K.

 

Ive been doing some research and I keep coming up with difference information regarding the timing chain. When does it need to be replaced? if at all

 

I'd be grateful for any help.

You need to replace it if it starts rattling loudly i would guess, my van has done 227,000 miles and I don't think it has been replaced at all.

Never heard of having to change one on a Zed ... logic says that a complete engine refurb would probably include a new chain but that's about it AFAIK

The 3 chains require replacing when they are stretched.

 

The tensioners should also be replaced as well as the upgraded guides and slippers.

 

The main chain tensioner can be inspected through the inspection plate and depending on how far the tensioner is extruding from the tensioner body, will determine how much the chain is stretched,

 

The chain can get noisy and performance will be effected as the valve train timing will be out in severe cases.

 

Now becoming quite a common issue.

 

Also best to fit genuine Nissan parts as most of the aftermarket chain kits are made of chocolate and not a job you want to do twice.

 

Hope this helps.

I've been told I'll need complete new valvetrain when I fit my bottom end.

 

Chains. Tensioners. Cams. Valves.

They should last the life of the engine, there are a lot of very high mileage VQ engines in other cars that are still going strong, Cefiro, Glorias etc and the earlier engines of the same design.

Just replaced all mine, VQ35DE, 10 years old and only 27,000 miles.

Indeed it is the track 350.

 

Retail price of the parts was circa £1000.00 (Genuine Nissan UK )
