Take a piece of hose and use it as a sound tube. Place one end near ear and the other check around the engine to pinpoint noise.

2007 pontiac g6 gt engine ticking noises what can it be?

ticking noise at idle are normally worn hydraulic lifters , worn rocker shaft or bushes worn on the end of the rocker where it contacts the end of the valve stem

I have a 2003 Dodge Ram 1500 4.7 with 166k still ticking after lifters replaced.

If there was a problem that caused the rocked to become dislodged I would have checked the rocker bushes and shaft and replace both. The rocker where it works on the end of the valve wears a recess that will move and then click back into place. I would use a 20w-50 grade oil and additives work at reducing friction . IF you need it to thicken the oil then there is something worn out.

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

The only thing under the rocker boxes is the rockers and the upper part of the heads with the valve springs. Getting to this area is not that difficult.

Remove the fuel tank and seat. Then, remove the six bolts that holt the top and middle rocker box covers on. Now, you're at the rocker plate with the rocker arms in it. You can also see the tops of the valve springs. Look and see if there is anything that might be causing your noise.

Now, keep in mind that a Harley engine is of an old design. It is a pushrod type engine with rocker arms that open and close the valves. They are going to make a little noise. Now, if you're having to get close to the rocker box to hear the noise, it's probably nothing to worry about. But, if you can hear the noise stand away from the bike a few feet, you may have a problem. But most things that might break or come loose under the rocker box will usually effect the way the engine runs.

Also, you could have an exhaust leak. It makes a "tick, tick, tick" type noise. Tighten the nuts on the two studs snugly but don't break them off.

Good Luck

Valve train noise

The ticking sound is most likely caused by uneven wear on the cam lobes. The next time you've got the valve covers off, take a look at the cams and you will likely see scuff marks on one or more of the high-points of the camshaft lobes. This can cause a ticking sound each time that part of the lobe comes in contact with the rocker arm. The only cure for this would be to replace the cam and rocker arms - which is not worth the many $$ it will cost. The noise may be annoying, but isn't anything to worry about. My Goldwing started making a ticking sound at about 90,000 miles - and continues to this day, now with more than 169,000 miles on the engine.
Uneven cam lobe wear can also cause lateral movement of the rocker arms - and a ticking sound as the rockers move slightly sideways on their shafts (note the springs on the shafts that hold the rockers lightly to one side).
I should also mention that pitted valve stem tips can also cause a ticking noise. In any event, do not run the engine with less than the specified .004" valve tappet clearance as this can cause valve damage and compression loss.

My harley has a strange ticking noise just started today its at the top of the engine under the valve covers

Your ticking noise could be most anything. You didn't tell me how many miles are on your bike.

Now, on top of the head you have the typical stuff that's on all four cycles engines with pushrod operated valves. You tappets down below that push up on the push rods. The push rods push up on the rocker arms. The rocker arms pivot on rocker arm shafts that ride in rocker arm bushings. The rocker arms push down on the valve stems that are closed by valves springs. The valves are also guided by valves guides. There could be wear in any one or more of these places causing the ticking you are hearing.

Now, whether or not the ticking warrants concern is how loud the ticking is. If it something that you have to "listen" for, I don't think I'd be too concerned as a bit of valve train noise is common in an engine with a few miles on it. However, if people are asking you what's that noise when you pull up, you need to have it checked out.

Pull the top covers off the heads and check for broken valves springs, missing or busted valve keepers, excessive wear in the rocker arm bushing. I hope this helps, Good Luck and ride safe.

Vortec 4.3 Ticking that is present at start-up and speeds up as I accelerate, what would cause this?

If you have good oil pressure, a few things come to mind, first it could be a loose rocker, secound it could be a woren or broken rocker, third it could be a weak or calaps lifter. If it sounds like its lower in the engine like around the oil pan it could be a rod or maine problem. But you say its a ticking noise witch leads me to believe its a valve trane problem.
