The ticking sound is coming from the valve lifters. When the oil filter is changed, air is introduced into the system, which causes air bubbles to form in the oil. This causes the valve lifters to "leak down", which is what causes the ticking sound. It can take several days for the bubbles to dissipate. It's annoying, but harmless.
Hopefully just a valve lash adjustment.
It's a rocker arm tapping at valve stem. Hydraulic lifters (hydraulic rocker mounts) are the common reason for the ticking. If it doesn't go away when the engine heats up, consider replacing the lifter where the ticking comes from.
The most likely cause of a ticking sound in a motor is a bad timing belt. A valve out of time can also cause a ticking sound.
Code P0300, Intermittent rough idle,
its your lifter ticking really nutting you can do about it dose it on all probes one of there down falls just check the oil level
The "ticking" sound that is most common among Saturn's is caused by a slightly expanded gap in the valve spacing. It could, of course, be something else, but that seems most common. If that's what's going on, it probably isn't worth much effort to repair. Valve clatter isn't typically a problem unless it gets severe.
you may have a bent valve
Valve adjustment needed is a possibility.
Sometimes a ticking sound is a valve lifter. The faster you go the faster the ticking will be. Make sure first it is not something stuck in a tire or something on the fan belt.
?? Lifters not getting enough oil ??
its the needle valve inside the injector opening and closing
Worn valve train? Hydraulic valve lifter worn or "hung-up"? Lack of lubrication to rocker arms?
buy new motor
your either about to throw a rod (which means you need it replaced before it gets thrown through the block) or you have a valve tapping which means the rocker needs adjusted
Take it to a professional and have the valve lash adjusted. Also replace the spark plugs.
If they are mechanical lifters, then there is an adjustment under the valve cover. If they are hydraulic then there is no adjustment, and while a different weight motor oil or special additive may help the ticking there is not real way to stop it.
the vacuum switching valve that run the valve are a common problem they are intermittent stuck closed so do not operate the valve
Collapsed hydraulic valve lifter? Rocker arm (valves) need adjusting?
There are multiple causes to intake and exhaust valve damage. These include preÊdetonation (knocking) and valve guide wear causing tracking issues.Ê
are you sure is a valve noise?? or is a piston slap?
That is a loaded question. Is the valve bent or broken? Did it damage the head? Is the valves simply ticking? You are looking at cost between a couple of hundred to a couple of thousand.
Now that's definitely a puzzler. I've never come across that before, I'd start by cleaning or throwing out all the aerators. Then clean out the H/W tank: - You first turn OFF the power to tank, then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, turn OFF your inlet valve and open the relief valve so air can enter the H/W tank.Let the whole tank empty -takes about 30 -40 minutes. Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, then turn on power. If, after all this, you still have intermittent hot I would call a plumber
Check the PCV valve. It is located in the passenger side valve cover near the rear.
As with anything mechanical the springs or hydraulics eventually lose their ability to properly lift the valve back up quickly, which causes valve float and loss of power at the top end of the engine.
