Any Forte owners hearing a clacking or light knocking noise from engine at warm idle? In my case, it's intermittant...sometimes totally silent, other times clack-clack...only at warm idle.

Sounds exactly like a sticky hydraulic lifter, but these cars dont have hydraulic lifters...or do they?

Any info would be appreciated, Thanks.

Not sure if the lifter are solid or hydraulic, but either way it sounds like you should have them adusted or at least looked at.

If they're hydraulic, then one may be running dry and may not have oil getting to it--possibly a clogged oil galley to the lifter.

If they're solid, mechanical lifters, then they have to be adjusted periodically as part of routine maintenence. I highly doubt that they use this design, as I do not recall in the maintenence manual any mention of valve adjustments.

Let us know what you find out.

Thanks for the input, Ferdy.

Even on a brand new car I was thinking it could be one or more valves out of adjustment. But it's intermittant, not there some of the time, there other times...always at warm idle only. That pretty much rules out valve clearance adjustment. Sticky lifter would be my best guess, but I don't believe these engines have hydraulic lifters, from what I've read.

It's an irregular light knocking sound...clack, clack-clack.

Anybody else experiencing this kind of engine noise on a new Forte?

I have noticed this on my SX Koupe, but it comes and goes. I just had my first oil change the other day, so I will have to see if the sound is still there.

Same here--but it is VERY light---sounds like the tappets to me---I think this is normal and not to worry---

"Comes and goes", that's what mine does. There some times, not there other times. I can drive it and hear it when I pull into the garage while idling. Then I'll drive it again and absolutely quiet the next time. Often the same day. It's only at idle. And I wouldn't describe it as clatter, but more of a light knocking sound. Clatter I expect with solid lifters, but not the knocking.

It's strange that it's intermittent. Sometimes it's totally silent, the knocking not there at all. I'm beginning to wonder if it's external to the engine, maybe an accessory pulley or a smog device.

I hear the same niose, I just thought maybe it was loud fuel injectors. It's more like a loud clicking that I hear.

 

[smic]

to make a comparison to the sound, to me it sounds like an older diesel engine sound but quieter

if that makes any sense

I'm getting that too, the diesel noise, usually when it's coming off a cold start. Sounds like valve clatter. The occasional knocking noise is different, like a knock, knock-knock. And it's only at warm idle, not while driving, not above 1000 rpm. It's not there most of the time now, was there all the time when new.

you are right, i just said that to someone yesterday...

Not the intermittent knocking noise, no way. It's not even there a lot of the time.

 

[gripphard]

not for the knocking. some clicking at idle & startup is normal. its electronic traction control. if that wasn't stated already.

MLA in response to questions if they are hydraulic. they are not they are mechanical.

 

[gumbyjunior1]

I agree. I noticed my Forte doing that lately myself. I will have it looked at on my 15K maintenance.

i have experienced that with low quality gas,more nervous but less mileage and noisy.good maybe a thread about the gas quality?Me,i'm running on Shell gas,less nervous but better mileage and cleaner engine,checked on my old winstar,no maintenance needed on engine,run like new at 180k,every 4 months checked at Ford(where they don't let you go without spending some money on OEM pieces)sparks realy clean at 175k,originals,no need to change,so... any other opinions?

I'm sure will go away after 10k or second oil change

 

[ADefiantRicer]

I have noticed my Forte is pretty noisy as well, my dealer told me that it is normal for these engines.
Hope this helps

 

[slimskater]

That's just how it sounds. There's nothing wrong with it.

Mine has been making the light clattering noise since I bought it brand new. It's at 67k miles now and there have been no problems.

You know, I just traded in my civic for my sx sedan. My civic did it and so does this car. I've heard every civic make that sound though. I'm beginning to wonder if its just a 4 cylinder thing, lol
