Timing Chain!
Turbo Mini Forums

Rare, but it can happen, mine failed.

Thought i'd post some pictures seeing as some people have a fetish for stuff like this.

Still N/A atm unfortunately, only got 500 miles out of this engine, and then my brand new timing chain just failed.

New one in now, new timing cover aswell, seeing as the old one was way beyond repair, not shown in the pictures, but the chain tried to saw it in half.

I'm very lucky there was no damage to the cam or valves or pistons. Engine is now back together and in the car, running. :)

nice! it may be worth telling the guys who you got it off, may be a bad batch?

Fair point, but i bought the chain maybe a year before it was put into use.

And i know the retailer personally, he hasn't had any other complaints.

Just my bad luck ?

Wow, never known that to happen, glad to hear theres no other damage

I seriously doubt it!

I had it happen to me, but on a Mercedes diesel - very, very expensive. And they say cambelts are a worry ?.

On a new chain Dez you have been exceptionally unlucky.

Tensioner used or not?

If something is worth doing, it's worth doing half of.

I bet it made a nasty noise. Glad there wasn't any other damage.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

You don't use a tensioner on a duplex? AFAIK

Noise - nothing, went to accelerate as the light went green, and just a... "Threeep" noise.

I may have been very unlucky with the chain, but I was incredibly lucky that there was no other damage.

You can use a tensioner with the duplex. It does a nice job of taking the slack out.

I suppose you could, i'm glad i didn't it would have been real messy with a million pieces of tensioner inside the timing case aswell!

But anyway, i hope everyone's worrying about their timing chains now!

Just 'cus it's very rare, doesn't mean it can't happen!
