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

Carried my 2005 free star to local shop and they said they thought it was a lifter or a rocker arm problem it makes a loud knocking sound..


Takes about 1 1/2 hours to figure it out. I can remove both valve covers in about an hour. 15 to 20 minutes to see which one is bad, if one of them are bad. Lifters and rockers arms usually make a ticking sound. Knocking is usually the piston rod. could be bearings at the crank or the wrist pin at the top of the rod. I've seen valve springs broken and only cause a ticking noise.

If ticking sound don't go away after flushing oil change is there a need to repair engine


Ticking sound is typical of slack in the valve train. Try using a wood dowell "stethescope" and touch it to the rocker arm cover over each cylinder. If a rocker arm adjustment is too slack, you'll hear a clicking sound rather than a muted murmur. If you find the noisy lifter you will need to remove the rocker arm cover and adjust it. CAUTION NOTE - It is possible that a hydraulic lifter may have some grit in the internal valve. That would stop the lifter from functioning properly.

2002 2.7 liter chrysler has a knock in the engine. sounds like it is coming from the valves


if the car has alot of miles on it , a little bit of top engine noise is nothing to worry about. if the car does'nt have alot of miles on it or the noise is real loud then you may have a lose valve or need rocker arm ajustment.

I notice my oil was low, cause it was running a little rough. So I put a quart in. Then it was running better. Then I drove it the next day and it started making a ticking noise and now it is getting...


the ticking , if you hear it on the top of the motor, will be a rocker arm,, it could be plugged and not getting oil, if its coming from lower down in the motor, it is possibly a stuck valve,, or a rod bearing , if its a ticking noise its more than likely the rocker assembly,, if its more of a knocking noise its lower in 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.

Pontiac sunfire valve noise


If it's a ticking noise that speeds up with the speed of the engine, it's a worn valve lifter.
You can try tightening it down by taking the valve cover off and tightening the bolt on the rocker arm, but don't tighten it too much, you will end up with other problems.

Loud engine noise in 1994 cavalier


I think the engine is most likely defective, the used one is the best bet, try and find one with low miles, you can do a nation wide search here.

Datsun stanza 1980 tappets (lifters)


This car has hydraulic lifters( tappets} therefore should not adjustment, you probably have a bad or weak lifter. But, in any case you have to remove the valve covers to make the adjustment. You will see the adjustable bolt on the rocker arm. rotate the engine until the valve is all the way to the top, [no tension on the valve spring] then place a feeler Gage in between the rocker arm and the valve stem, adjust the rocker arm until the feeler Gage is snug but not tight. Do this with each valve. Check the book for the correct Gage to use but I think it is a .018.
