What would cause a constant ticking sound in a Jeep Wrangler engine?
Detonation....Needs to be fixed immediately
It is probably not detonation as stated above, rather a lifter is sticking and needs to be replaced.
Also, the rocker arm bearings can get worn out. As stated above, just replace.
>Both My 4 litre and my old 2.5 litre ticked when cold. As soon as the engine warmed up it went away.
There are two distinct things in these engines that will cause a tick noise and I've had both occur in both engines. Detonation is NOT going to cause a constant tick as you're saying.
1: you have either a sticking lifter or sticking exhaust valve. My 4.0 wrangler does this when it's cold, I've come to the conclusion that it's an exhaust valve because if you give the engine a minute or two to "cool off" at an idle before shutdown, it seems to not tick the next time it's started. This was never a CONSTANT problem, was more intermittent.
2: You have a leaky exhaust manifold gasket. THIS is more likely your tick. I've had this occur on EVERY jeep I've owned. I think this is due to the fact that EVERY jeep I've owned came straight from the factory without nuts on the exhaust manifold studs at the extreme front and rear of the engine. You need to replace the gasket, torque the manifolds properly and install nuts on the nutless studs.
ADDED TO HIS LIST....
3. Worn cam lobe.
4. Crank bearing/seal worn.
5. Pistion walking.
6. dead spark plug
7. bent push rod.
8. bad roter/cap - thus spark plug not dedet.
9. bent connecting rod.
or your timing could also be off.
Or worst thing worst you blew a piston due to your side wall giving away. this is a common problem on older 2.5liters it happens in the number 1 or 4 cylinder mostly due to un-even cooling. Mine happened from a radiator leak that i didn't notice, and my bud's from and air pocket. If your not offroading and or beating it this shouldn't happen.
Whatever it is get it fixed before you need a new enigine.
All jeeps have a light knock but its just from normal rod/value movement.
ticking sound in engine is usually not caused by a timing belt ticking is usually caused by worn cam shaft or clifters most cars now have hydraulic lifters. if oil is low it will cause ticking. if a lifter is worn it will cause ticking these should have been ckecked for wear when replacing timing belt
Why would a 1997 Dodge Caravan engine make a tapping-ticking noise that went away after warming up but now is constant and seems to come from the top of the engine?
The 3.0L engine had a problem with the lifters that would cause the top end to tick. There is a TSB i believe on how to fix it. If the ticking is coming from the bottom of the engine (sometimes hard to tell) then you might have a Con-Rod knock that starting to show. Eitherway take it to a mechanic for diagnoses.
If the ticking is coming from the top of the engine it is likely the Hydraulic (valve) Lash Adjusters. A fresh oil change using a quality oil and ***an OEM filter from the dealership*** should clear the noise up within 15 minutes of driving. Use of a non-OEM filter can cause valve train ticking noise.
What would cause a loud ticking noise in a 2001 Jeep Wrangler that seems to be coming from the valve cover?
Its possible that this ticking sound is caused from driving fast for prolong periods. Its possible that its not the engine that is making the sound, but the exhaust system somewhere. I hear a ticking sound if I drive over 140KMh for long periods. It always stops once the car cools. I hopes this helps.
Can a bad alternator on a 97 Nissan Maxima cause the air bag light to go on with a ticking sound that eventually causes the engine to shut off?
What would cause an 1989 Firebird 305 TBI engine to make a ticking sound after going through some water?
What would cause a ticking and dash lights diming flashiing the ticking is present even when the ignition is off?
In your 1994 wrangler when you get to about 70 mph the check engine light comes on and the speedometer flucuates?
The check engine light is on in your 1998 Ford Explorer there is a faint ticking and noise coming from the engine what is it The oil and transmission fluid was just changed before the light came on?
The check engine light is not related to the oil or the transmission fluid systems. It is related to fuel control, computer, emmissions control systems. The faint ticking you hear may just be the normal noise coming from the fuel injectors. All fuel injectors make some kind of ticking noise while they operate. I would say, if the check engine light has anything to do with the services performed, it would almost have to be…
If your 2001 Sunfire makes a ticking noise all the time but has been ticking and otherwise running fine for over a year is it a gasket head If so what is the best solution; let engine blow replace?
No! ticking noise is usually lifter noise. your engine is fine.(to a point) try changing your oil put in a thicker oil to prevent metal to metal contact. go for a 15/40 20/50. let it run for a while(few miles), if it doesn't stop buy an additive called "engine lucas", that will dilute your oil just enough to allow it to lubricate your lifters. also when your oil level drops or your oil becomes dirty…
There is probably too much clearance between the rods and the crankshaft causing the motor to knock. If this is the case you need an overhaul job on the engine. The clicking sound is probably cause from using too low octane gas or your firing is set a little too high. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info answer knocking sound comes from worn bearings and parts in lower engine ticking comes from tappets, or more specifically the hydraulic lifters in…
