Timing Chain?

[Chrisxn]

Right, recently I've noticed my car making a kinda clattery noise in the low revs. its not overly loud, but its noticeable! Is it the timing chain? and if it is, how much is it to replace?


I think with all these problems, its gettin silly keeping the micra You know when you feel like you're throwin money at it?
:down:

 

[joesouthgate]

Timing chain most probably and they will usually go well over 100k with no problems.

 

[Chrisxn]

Awh, Mines only just got 77k!

 

[joesouthgate]

yep mines only got 79k and it clatters, they all do it so i wouldnt worry±

 

[Chrisxn]

Ok, we'll see how it goes since the breakdown, Im paranoid about every noise it makes! lol

 

[Alfonze]

I had that problem, but it turned out to be the heat shield that was loose and was removed not sweet as a badger, mines done 87k miles.

 

[Chrisxn]

Nah, I don think its the heatshield.. Its a bit too deep of a sound.. I imagine heatshield would be more... i dunno.. You know when you're chain ballses up on your bike? lol! Its that kinda sound


Also, quick question while Im here,

1998 prefacelift.. What are the sidelight bulbs I need? Im lookin at some LED W5W bulbs. Are they right?

 

[joesouthgate]

yep they're the ones.

 

[Chrisxn]

Awesome Some nice sidelights to go with my new Osram Nightbreakers then

Thanks!!!!

Chris

[Alfonze]

I didnt think it was the heat shield but it was

Keep the servicing regular and you'll have no problems with the timing chain.

Most K11s have some kind of chain rattle, It's not really a problem.

 

[whipit]

I once had a 2001 k11 0n 11k miles with chain rattle............it comes standard!

 

[Dewgel]

Mine has 140,000 on, and sounds very much like a diesel =D

Say goodbye to that engine soon.

lol haha, well a replacement engine won't too much. lol

 

[Dewgel]

lol haha, well a replacement engine won't too much. lol

Aye the chassis's done 140k but the engine in has only done about 40k lol so it's ok It does sound like a diesel but am not arsed it goes from a to b lol.

 

[Chrisxn]

Dewgel, if the engine dies on me, Im comin after you for jinxing me!!

Ill check the heatshields, but I dont think its that.... I'd imagine that'd rattle more if I was sitting on bite (that being when the gearstick shakes most, I'd assume everything else would too!)

Humm.. lol!

 

[Alfonze]

lol I almost got a rew engine cause of it lol

It'll last forever mate.

It's cheaper to just get a newer engine with lower mileage dropped in than to faf on changing the chain to be honest, but just keep that enigne till it just does nothing at all.

Like everything, get the most out of it

1.3 engine will set you back about 200, excluding fitting.

 

[jowley]

its only £70 quid for the modified chain and tensioners 2 hour job to fit easy enough

 

[frank]

2 hours is goin some fwn , it,s a sump and oilpump off job, to change both chain,s

 

[Ed]

Most it seems only change the top chain.

 

[whipit]

Top chain takes around 20mins once you know how to time it up. Is the modified chain from Nissan?

 

[frank]

if you only change the top chain, you have to hacksaw the protrusion off, (the one that stops the idler and chains from dropping down if you take the head off), btw

 

[whipit]

Really, hhhhmmm oh yeah i remember now! Long prybar and a hammer, 1 min!

Although advise no ones else to do it, not sure why since it worked perfectly fine for me but there are risks.

i hope you stuffed some rag in first, to catch the shrapnel ? :grinning:

I know i developed some form of method although don't quite remember what it was. Did this when fitting the 1.3 cams into a 1.0....(the next owner recently blew the gear box lol).

 

[frank]

i found that sawing most of the way through (with the rag in) was best, then it snaps like a carrot (held in some pliers)

That was the method i developed! Pliers!

 

[jowley]

yes there from the dealers

 

[Chrisxn]

Sorry for the late reply, I havent been on the interweb in a while :S

Thing is, I've never had an engine apart.. So I couldnt do it myself!! unless theres a guide or something!

Ill just keep it goin.. If worst comes to worst I'll prolly break it. Most of its in good nick! PLus theres a reconditioned gearbox thats only done a couple k miles.

We'll see how it goes

as said though most of this thread, its ok it just makes that noise. Nothing to worry about, you will find that it may snap somewhere around the 150k miles mark.

 

[Bash1989]

Well what happens when it snaps? will the engine seize?

 

[frank]

the valves get bent :doh:

 

[Bash1989]

Ouch, might get my chain replaced in the new year then lol

 

[frank]

your talking, min £500 to have them both replaced fwn, it,s only a 1/2hr job to inspect them tho

 

[tomas19]

mines done 141000 and it dont rattle at all only a tiny bit on tick over but thts with my head in the engine bay lol

 

[esha]

Oh god i think i may have to get mine looked at then, im on 155k now! But its not makin a lot of noise at the moment to be fair!

it depends how the car has been driven/maintained, my old super s top one was shot at 100k (but it had had a hard life tho :glance

 

[young nav]

my super s chain let go at 97k bent the valves in cylinders 2,3 and 4 its not hard to change so why chance it

 

[bathtubtom]

I did my daughter's rattly chain at about 50K.

I changed both chains, tensioners, guides and idler wheel. I re-used the original crank wheel and cam wheels.

I formed the opinion the trouble was caused by hooked teeth on the idler wheel for the upper chain. I reckon I could've quietened it enough to sell by just changing the top tensioner. The chains looked to be hardly worn at all. The only noticeable wear was on the said idler and top tensioner.

I haven't a clue what it's servicing regime (or more likely lack of) was before we bought it. The engine was warm when we saw it - I know better now!

 

[esha]

To repeat what was said at the beggining of the thread, dont think that the rattle your hearing is definately the chain, cos for a few weeks now ive been hearing what i thought was the chain becoming VERY loose, and yes its turned out to be the heatshield on my front pipe! And I fit exhausts for a living so I should recognize that sound! Hey ho means i can keep the wallet in my pocket for a while longer!

 

[capnmchl]

Thank god for timing chains.
