Ticking noise in engine

I have a 2006 Rubicon and the engine has developed a mild ticking noise at around 1900-2000 RPMs. The dealer has repleced the CAM and lifters, however, the ticking noise is still there. The dealer explained this as a "normal" engine noise for the 2006 model. This sounds a little fishy. Any oher soultions?

    Almost the same problem as the last guy. I hear a loud ticking sound at 1700- 1900 rpms. I had the dealership replace the lifters with only 16,000

    miles. 9,000 miles later the same sound is back at the same rpms.

It sounds like the lifters are still sticking. Change your oil/filter then after 500 miles change it again. Since motor oil has a mild detergents, a couple of changes should hopefully remove any buildup from around the lifters. Do not use "motor flush". Even though your engine is fairly new, it may remove too much buildup and flush it onto your crankshaft bearings. You may try some marvel mystery oil also and I've heard seafoam does a good job, if you can find it. Mine started ticking after using one of the super thick oil additives. I'm still trying to flush that stuff out.

If motor is making a ticking noise, what can be done?


It is normal for engines to develop ticking noises as they age. The valve lifters are usually hydraulic and can change ability to hold fluid as tight as when new, cams and cam followers can wear down. The cost to remedy a slight tick is not worth it.

1986 mighty max 2.0 engine makes a ticking noise most of the time. At higher rpms it stops. What could it be ? It kind of sounds ike a vaccum leak ? maybe ?


A ticking sound is usually a valve and if it stops at higher rpms I would guess it is oil related. Seems like the oil pump might be getting tired and not pumping enough at low rpms.

The sound you hear is the metal parts of your exhaust system and catalytic converter cooling down.Some cars are louder than others but the sound is perfectly normal.

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.

Ticking noise


Do this first: Change the oil. I recommend Havoline, or Valvoline 10w30. Make sure to use a GOOD quality oil filter(WIX only). Then buy a can of "Seafoam". Follow the instructions exactly! After 500 miles, repeat the process(except for the "Seafoam"). The "Seafoam" should help to clean up any carbon or junk in the engine. When you change the oil again, add "LubeGuard Engine Treatment". This should help stave off the engine replacement blues.
