Sticking lifters have a very distinct sound unlike bearings in pulleys. Much of the time you can free up sticking lifters with oil additives like Risilone which will clean the internal parts of an engine and free up sticking lifters

2007 Acura tl 3.2 110000 miles engine makes a clicking noise when idling& driving I'll done the oil change and transmission flush but still haerd the clicking


At 110000 miles it could be:
1. the serpentine belt or one of the idler pulleys
2. the water pump
3. the timing belt or one of its idler pulleys
4. to a lesser extent, the power steering pump
5. a valve lifter
Here is a video showing what is on the front of the engine
You may want to get a mechanics stethoscope and carefully start trying to pinpoint the noise [keep fingers far away from belts and pulleys, I know 3 people that lost finger tips this way].

2004 sebring 2.7 has grating noise when cold. Engine is quiet once it's warmed up. One mechanic told me belt and tensioner need to be replaced. Another told me this is a internal noise common


Cams are WELL known for knocking on these engines. It isnt a sticky piston ring or timing. The cams have a wear point on the lobes and will make noise till warm and the oil is warm. I habe worked on many of these engines. Best bet is to run a good oil and a little heavier year around like 10w 30 high mileage oil. Even lucas oil additice helps with the noise because it doesnt drain down like oil and keeps the lodes and lifters oiled better.

2005 chevy optra hatchback. Engine making loud ticking noise and the check engine light is flashing on and off. When driving, feels like it's about to stall, and uphill is a struggle.


Check your timing belt, even if your only symptom is loud lifter noise on startup. The belt/pulleys are not designed with deep V grooves and the tensioner is manual, not spring loaded. If the crankshafts stops at a certain point and creates any slack in the belt to the top right lifter pulley, that pulley, under tension from the spring loaded valves, tends to jump a notch. The only solution, after refixing the timing belt correctly (make sure you know how to do this) appears to be careful over-tightening of the manual tensioner and prayer! Bad design.

Try slipping the drive belt (fan belt, alternator belt, or whatever you want to call it) off the engine, then run the engine momentarily without the belt. If the noise disappears, at least you now know it is not an internal engine problem, and it will be an issue with one of the pulleys, or belt-driven accessories.

I have a loud ticking in the motor. car fires right up what could it be ? was told it was the timing belt then told that it was the lifter.


I would guess that it is a lifter. this happens over time. If it were the belt youcar would be running worst, probably missing out and the noise would be of the slapping, thud sound. you can try some valve medic, this might help with the lifter noise. But things do wear out and a few thousandths clearance on the push rods and rocker arms will cause a ticking.

BAD LIFTERS WILL MAKE A NOISE.IF VALVE LIFTERS AND LOWER SPRING SEALS BEEN REPLACED AND LIFTERS STILL NOISEY.EITHER ENGINE OIL TOO THICK OR ENGINE NEED OIL CHANGE + FILTER CHANGE.DIRTY OIL CAUSE LIFTER NOISE OR OIL PASSAGES IN THE CYLINDER HEAD STOPPED UP NOT ALLOWING LIFTERS TO GET THE RIGHT AMOUNT OF OIL.OR OIL PRESSURE TO LOW DUE TO FAULTY OIL PUMP.OIL PRESSURE SHOULD BE 29 PSI @2000 RPM. TRYING ADDING SOME SEAFOAM CLEANER IN CRANK CASE IF OIL PASSAGES STOPPED UP IT WILL CLEAN OUT OIL SLUDGE.GO TO AUTO PARTS STORE TELL THEM YOU NEED SEAFOAM.AFTER 500 MILES YOU NEED TO CHANGE OIL AND FILTER AGAIN. SEE IF THIS HELP BEFORE SPENDING ALOT OF MONEY .

My Navigator makes a rattling noise at startup and then it continues to make rattling noise while idling. What could be? Possible lifters, rocker arms, and pitons rods possibly?


if rattling sounds like you have a bad pulley bearings on pulley going out pop hood and look at belt with running see if it is moving correctly not going in a back and forth motion like warped llook at pulleys see if they are displaced

Noisey drive belt, possibly alternator, belt


sounds like idler bearings but you have to release the tension to check,Also you can check the rest of the pulleys also at this time. I dont think you have to drop the engine.
