2012 CRD Timing chain life.

[Coldcomfort]

Hi all, is there a end of life schedule for the timing chain on a 2012 CRD wagon?

Cheers all.

If you get a hunch and want to change it, here's a cool video

I've watched that before. I'm not sure that I'm up to it. Also I don't want to do it unless there is a compelling reason. My truck has just passed the 250k mark and I'm just making sure that any sudden surprises are not coming my way.

Does your service manual say anything about it. If anything the chain tensioner might need replacing at certain klms...

Yer I'd be leaving it alone...

I've got a 2012 CRD and know a Nissan Mechanic, there is no scheduled timing chain change listed. He advised to leave it alone. I aked him to check as I was doing my hoses and serpentine belt.

Timing chains don’t have intervals at all. If your engine oil has been changed regularly and you’ve been quality oil then you shouldn’t have any problems. A customer of mine has an early di with over 350k on his zd, it has mass amounts of blow by and at one point was dieseling on it’s own fumes till I fitted a proper catch can but still no timing chain noises.

Thanks guys. Thats what I was hoping the case would be. I'll be leaving it alone for sure. But I'm glad I asked.

Can't speak to your specific engine, but the Mitsubishi ute I had running a timing chain was spec'd for "checking" at 300k. It was a duplex chain IIRC driving the balance shaft and cams (hydraulic tappets)

There may or may not be a spec available for your engine...generally given as a length over 10 links. But basically if you lay it out in a line and can feel any slop when you push-pull, it's poked.

By the time your chain is "making noises" it's already past-worn.
It could well go a million miles without catastrophic failure, but your timing, balance, economy etc will all be to shit.
