Rattling engine noise.. normal?

[TOPoftheworld]

Hi, got a stock S14 not too long ago, before I bought it I did get an inspection from a credible place, said everything was in fine working condition

I never really listened to the engine idle with the =hood popped= until today, noticed a rattling noise made when engine is turned on. The car drives well and everything, just don't know if this engine noise is normal or not for the car. I'm probably just being paranoid but I'll double check with RS just in case before I take it to a garage (if i do probably after winter cause im garaging the car when it snows)

Video of rattling noise in video, sound gets clear at around 9 seconds .. sorry for the crappy iphone quality video, you can hear the sound nice and clear though

OH Right.. engine is a fully stock KA24DE other than a drop in air filter.. not a rebuild or swap or anything, 130,000 km 1998 S14 if that helps

could be timing chain?

[TOPoftheworld]

Hmm .. i have no clue.. really noob about cars / engines lol

But after few hours of internet searching there were a couple of people saying something about timing guides being worn out or something

I have completely no clue.. just wondering for now if its a normal idle noise for the KA24DE for now

[gloors]

had this problem with my s13. im guessing either your tension guide is broken or could possibly be a water pump problem as well. its a common problem for ka24de

Remove the valve cover and unbolt the top chain guide. My s13 does that too.

How positive are any of the above posters about the timing chain guide? Is this problem serious at all, and how much does it cost to replace?

[satek]

You don't replace the top timing chain guide, you unbolt it and set it on fire because it's useless. You should look into lucas chain lube, I heard it keeps the chain quiet.

Mine continues to rattle 24/7 even after driving for like an hour or when car is completely heated up QQ does yours only rattle at start up when its cold?

Hopefully it is indeed this "worn out guide problem" and not something serious

[SkunkWorks]

It's just the worn out guide making a rattle. Nothing serious. Happens with nearly 95% of KAs out there.

ok after watching your video it COULD be ticking lifters but most likely still the guide. You should take it to a shop.

mine only rattles on start-up

[GabAlmighty]

Hmm, interesting. Was gonna say lifters but it was a little fast paced for that. Learn something new everyday.

this guy has the same sound urs does and he replaced the guides and it went away

so yeah don't worry about it not a huge problem

[SpuGen]

No.
It's the Guide.
There's 2.
One up top, and one in the front.

The one in the front requires you to remove the Cam Cover.

just take a long screw driver and use it as a sethoscope to pin point where the noise is first

[TOPoftheworld]

Talked to a bunch of garages about this problem

Some have said I need to replace the whole timing chain.. but my car is only at 130,000 kms and I do believe timing chains last a long ass time

Others have said just the remove the guide and it will be okay,

Does anyone know whether i should go with the whole timing chain procedure for my car at 130k kms or save a butt load of money and just remove the guides? Thanks

[satek]

Timing chains last like 3 times longer than timing belts, so removing the guide is really all you need to do. If you are really paranoid then get your chain replaced.

[SpuGen]

....

How about you just take off the Chain Guides first instead of paying a shop to take away your money for a part that doesn't need replacing for A LONG TIME.
It's a Timing Chain. Not a belt. They last MINIMUM 250K

Take it from a 240 owner.
I've never seen anyone replace the timing chain.
They've only taken off thier Chain Guide.

KA-T.
No Chain Guides.
Hasn't replaced the Timing Chain. And that's his drift car on a rebuilt motor (block)

Alright, I guess I'll try to remove the guides without messing up my car LOL

[EmOne]

[cityvanluder]
