First I would have to ask, When was the last oil change? If it has been a long time. Change it, but before you do. get the engine to operating temperature, add 1/2 of transmission fluid. Let it run for 15 to 30 minutes. ( transmission fluid is high detergent and cleans the engine/hydraulic lifters) then change the oil. If after you add the transmission fluid and the ticking persists, then look at worn rocker arms and push rods. On rare occasions, springs break and bolts strip the threads out. This usually causes a misfire though.

Hello, It could be a rocker arm or a weak hydraulic valve lifter. I would also check the oil level.

SOURCE: the rocker arm ticks

before trying too much the lifters will sometimes bleed off some of the prime they have. first try putting in a pint of marvel mystery oil. if that doesn't fix it run an oil pressure test to see if you need a new pump or new lifters

SOURCE: knocking or ticking in the

you are right its either a rocker arm broken or loose or it also could be a broken valve spring so look for all three While you have the valve cover off to save you coming back and looking again ... thanks Jerry

SOURCE: ticking noise from engine

if you've got a few $$ to risk ,try some synthetic oil with new filter ...it often work good for these kind of noise as long as it is not a loud knoking nois ...if it is only a fast clic clic nois it will probably work!

Have a 2006 chrysler 300, 3.5 with loud ticking noise during acceleration, also experiencing loss of power. Replaced both rocker assemblies and performance improved but ticking is still there.


sounds like bad valve seats or seals do you have a oil pressure gauge on your dash.check the pressure.then check your return ports on top of the head thats giving you the problem see if the oil is returning to the oil pan.sometimes the return ports become blocked and the oil stays on top of the head.and see if the oil supply is making up to the head.hope this helps.mark

I just got the rocker arms changed in my 06 dodge stratus and it is still making a lil noise how long does it take to stop making the noise


If the valve lash is good it should not be making noise. Sounds the mechanic maybe did not get the lash just right. I would ask him to readjust the valve lash or at least check it. The rockers started oil as soon as you started the engine and the oil pressure came up.

A light but audible tapping under the hood that accelerates when you step on the gas.


Sounds like something in the valvetrain, a lifter or rocker arm. Could be from lower oil. Is it a metallic sound? Is the noise coming from a certain area of the motor?

WHEN ENGINE IS RUNNING IT TICKS LOUDLY AND WHEN U ACCELERATE IT TICKS FASTER.


A worn valve lifter or a loose rocker arm is causing that noise.To find out which one it is, the valve covers have to come off and check each one. If the rocker arms are snug, then it's a lifter, in which case the whole top part of the engine has to come off to get at the lifters.
