No real worry, try adding some Marvel oil to it or using a decent synthetic oil. Either, or both should help get any gunk out of the hydraulic part of the lifters, and neither will do any harm. Don't expect the noise to disappear instantly though, it took a long time to get that way. Don't use any heavy additive or single grade oil (like 40 weight) That will jam up the oil control rings on your pistons.

My 1998 jimmy runs rough the first 3 to 5 minutes it running and makes a ticking noise. After that it runs normal.


Ticking could be your lifters. If it is a bad ticking then you could have thrown a rod but that should be noticeably louder. If you are using a fuel or oil treatment I recommend Lucas additives. It is going to take a few tanks of adding this in to have a lasting effect. One time just won't do it.

A ticking sound on a 06 ford f150 super crew 5.4L


Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

When i spped up my truck makes a ticking sound ..what could that be?


It is more than likely the lifters ticking. After a lot of miles then the hydraulic lifters don't hold oil pressure and start ticking. Engines will run for a very long time with the lifters ticking. I have a 1972 Nova that the lifters have ticked on for about 10 years and it still runs fine.

Ticking noise on a 2001 town and country is it really a lifter


Probably, but other things can cause what sounds like a tick as well. Early rod wear can sound a lot like a lifter tick. Sometimes even the transmission can develop a ticking in the area of the torque converter/pump. If there is no other apparent issues, chalk it up to old bones - after all you have 186K on it.

1999 civic honda . engine is ticking when cold for 2-3 min. can it be fix ?


This is a sign of an aging vehicle, but not to worry, it can be helped if not cured completely. Normally this is caused by sticking lifters from carbon buildup in your oil. First check the level of your oil, make sure you havnt been running on half capacity. Then I would recommend going to the auto parts store and purchasing an oil additive like sea-foam or one that says it helps with sticky lifters and engine knock. Add this to your oil in the appropriate amount. Drive for a couple hundred miles or until the noise gets better. After that, change your oil, and dont use the additive with the new oil. this should last for quite a while, but with an aging car, you may have to do this once or twice a year, or perhaps every time just before you change your oil.

sounds like lifters, rods normally make a knocking sound try putting a couple of bottles of engine flush in and run the car around the block a couple of time then drain the oil and change the filter and replace the oil with a quality 15w 40 grade oil and see if the noise clears up. if it is still there you can try product called moreys oil addative this often helps quiet down liftes if still no good oyu may need to replace your lifters
