3 chains ONLY (1 chain from the crank to idler sprocket/ 2 from idler sprocket to cams). This ticking noise are usually associated with poor oil flow through the upper part of the engine or sticking lifters. If this vehicle has over 80k miles, have the oil pan and oil pick-screen cleaned!! If the problems not severe yet, it will go away!!

Grinding nose from timing cover and a tick from valve cover could that tick be chain slap or is the 2.4 a no tolarince motor


The Tick is more likely worn lifters and cam. The grinding noise is most likely the timing chain guide is worn out or broken. Possibly a bad timing chain Tensioner. That IS an interference engine.

2006 mazda 6 2.3 65,000 miles. It started making a very, very loud ticking / knocking noise at all times following the rpms. The valve clearences are within spec, but that's all i've checked. ...


Mobil oil won`t cause this problem however if the mechanical parts have just succumbed to metal fatigue or defect.the noise could be rocker arms,connecting rod noise or a failed piston.its hard to say without hearing the noise as it is to try and describe the noise.

I own a 2004 dodge intrepid and it has about 180,000 miles on it. i recently replaced the water pump, oil pump and the timing chain. now when i got the timing chain fixed some how it was not put on...


it is possible that when the timing chain was incorrectly fitted that damage was done to the cam lobes or followers and that is the ticking noise
the oil recommended is too light for a used engine so go to 20w 40 or 30w 50
take it to an accredited repair shop for a proper diagnosis

2002 hyundai santa fe - engine noise ticking -car seems to be running fine but has started making a ticking noise - was formerly very quiet


The cam chains have developed slack and are slapping on the cam chain guides which helps prevent the cam chains from popping off in case of slack developing . The chain guides are made of some type of plastic material and develop significant wear.

A loud ticking noise?


No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.

Loud tick & knocking for a 1zzfe engine from 2001 toyota corolla


from what you are describing it sounds like a lifter/valve issue, i am a ford man i don't know if toyota do the same thing, but if they use inserts for the valve seats it is possible a valve seat has been dropping just has not dropped fully out to cause engine damage. buying a new engine will actually cost you less than an overhaul/rebuild anymore. the parts will cost you almost as much as a new motor will with all the machining that maybe needed.

Ticking noise


It is part of the waste gate just above the gas tank. It periodically checks for leaks and pressurizes and releases. Gives a ticking noise when it does this. Not a problem and GM is aware of this and said its normal on our cars.
