like the title says, i have a valve train knock at idle. ive had it for a few weeks but have been neglecting to take it in as that tends to be a pain in the ___ here in seattle. my buddy is a mechanic for a euro shop mainly working on bmw and benz and he told me its a valve train knock. you can hear it from about 20 feet away...but its not loud...kinda faint. thoughts before i take it in to the stealership?

btw, yes i am under warranty. i just hate dealing with them b/c theyre all morons.

 

take it in, its probably about to go boom

 

i dont think its about to go boom. once you push on the gas, even the slightest, it goes away. when it falls back down to idle the sound returns. the car isnt running weird at all and it only has 14k miles. so, no boom...lets hope.

 

most likely re-shim the valvetrain to stop the noise. get it in soon. and be prepared maybe the service advisor is deaf and says "sounds fine to me"..

 

mine does the same thing i have an appointment tomorrow for it. i have 20k on my car

 

based on what they tell you....is how i will go about this. the stealerships here are really retared and i want to know as much as possible about this before i go in. i look forward to what they tell you! keep me posted

 

Mine does this noise as well. It's 08 with 21k miles. I heard syntetic oil makes valvetrain louder. I think its normal and you have nothing to worry about.

 

yea... i think it is normal...most of people here have a knock/chik chik sound!

 

mines not the normal "chik chik" sound. sounds like someone has two medium sized rocks in their hands and are slightly banging them together.

 

what mods have you done The dealership said since i havd a hearer and CAI that i took off factory covers and that they prevent the sound. Like the cover over stock header and rubber for air box. they said that is normal

 

i heard the same...

 

no mods on my 08 tc. not even running synthetic oil. bone stock except for the hids.

 

just take it in to a dealer and see what they say.....

 

i know that the cover over the engine is foam lined for noise reduction, so they could be telling the truth about that. yeah there's a reason it's foam lined.

 

if its more of a high pitched tick...prolly just valvetrain. It is when its deeper that you gotta really worry.

 

make a vid a post it up.

 

mine ticks since day one and even louder since i run mobil 1. its called hte toyota tick and my old toyota pickup did it too

 

its on i put all the stock stuff back on and still have it they are full of bs

 

oh hmmm.. then nevermind that idea. you should get a mechanics stethascope and listen to various parts of the engine while it's running, so you can pinpoint this noise you keep hearing. that'll help isolate where it's from.

 

thats gunna be hard its loud as ____ and comes from everywhere
