What cause tick tick noise in my cylinder head,funny part when I drive& apply clutch the noise disapear.(Ford bantam 1.8diesel endura de) do I need to change oil or bent valves? Pls help


A ticking noise in the cylinder head area is usually associated with the camshaft/followers, which may be worn.
Here's a couple if images: cause-tick-tick-noise-in-cylinder-drn4r4jcf5cpqfgonvky3zim-5-0.jpg The lobe of the camshaft wears - becomes 'rounded'

cause-tick-tick-noise-in-cylinder-drn4r4jcf5cpqfgonvky3zim-5-1.jpg The cam follower - what the camshaft pushes against to open and close the valves - can become worn.. 'dished' at the top.

It is unlikely you will have to change any valves, unless of course there is wear/damage.

The reason why the tick noise disappears when you are driving is because oil is getting pumped up to the camshaft area, between the cam lobe and the follower and acting as a 'cushion'.

A vehicle that has hydraulic lifters.. they control valve clearances by using oil. Like conventional cam followers, they can wear.

Changing your oil won't cure any wear. You could try using a valve train additive to try and quieten things down.

Why does not start?


I have never heard of an engine noise being described as a tick tack rattling noise. (I assume you mean Tick Tack candy/breathmints?) \

Either way, if it doesnt start, but just makes a rattling/knocking sound, I would ask you did it just quit on you and not restart? Or did it get you where you were going and then would not start when you were ready to leave? If the answer to the first question is yes, then you are likely facing a broken timing belt. The sound you hear are the valves coming into contact with the pistons when you are cranking the starter. This is a bad sound. Lets hope your answer was no to the first and yes to the second. Are you sure have gas? I cannot tell you how many times people have told me "It just won't start!" only to pour a gallon of gas in and varrroooom! What about oil? The tick tack sound just doesn't sound like a healthy engine sound in my head. Do you have oil in the engine? Does somebody hate you enough to drop nuts and bolts into your intake manifold? That would sound like tick tacks. BIG GIANT tick tacks, but tick tacks nonetheless.

Iratic tick over when warm


Could be many things. Sometimes Exhaust flange joints will get a gap in them and tick. You could be hearing the Injectors, or hydraulic lifters.

The exhaust tick and lifter tick both are temperature sensitive as opposed to the injectors.

What you could do is run the engine and drain the oil and put in fresh cold oil. The first few seconds the cold oil will be thicker and if it is a lifter problem, the oil will cushion the noise temporarily until it warms. The exhaust will already be hot, so you will notice a noise on startup. If the noise generates later, its an oil related problem.

The exhaust flange problem can sometimes be heard when backing up and reversing direction. The Torque puts a strain on the pipe joint as the Torque changes from Reverse to Forward.

I hope my Solution is helpful.

Engine tick on a 2001 hyundai tiburon. Replaced lash adjusters but the noise is still there. Not present when idling. Only can be heard when accelerating/providing fuel (via gas pedal). Tick increases...


can be a problem with lifters, bent/broken valves.. timing could be off, could be a balance shaft. this is something you want to take into a shop and have looked at.

There is no picture and there is a tick tick ticking noise coming from inside the TV


The ticdk tick sound is probably the switched mode power supply making noise due to the fact that there is a shorted component inside(may be the horiz. output transistor). You may need to have service personell look at unit and get an estimate...this is older set n may not be worth repair

Washer fills and spins but does not agitate


Im sorry to say, it sounds like the transmission in the washer may have gone out, the unit it self sits at the bottem of the main agitator shaft under the the tub, you may be able to have this replaced, but shop around for the right price.
