It could be a valve lifter. It also could be a rod bearing. In either case, replacing the whole engine is more drastic than you actually need to go. Replacing bearings can be done...

Can lifters be replaced


Oh yea, lifters can be replaced , best if you replace cam an lifters together ! Loud knocking is not usually associated with lifters , they usually make a ticking noise ! Knocking noise is most usually in the bottom of the motor , main or rod bearings . most of the time rod bearings !

Bad oil pump knock


ionMr. Hugo. what to what you do have is the viscosity of your engine oil. Most probably is either long mileage used engine oil and due to that oil mud built up inside the engine, in the oil pan and most likely close to the oil pressure pump filter reducing the suction and that is why you do have cold lifter knocking,as the engine oil that time is thicker and when it gets hot become thinner and lifters stopped knocking. My persona advise do flush the old engine oil using ( RESTORE MOTOR CLEANER ) pour it into the engine old oil,start the engine in idle and few times reving it for 40 minutes. Then drain it and renew the engine oil with new and recommended engine oil for your engine,by renewing the oil filter as well. Also in the new engine oil put also (RESTORE FRICTION REDUCER ) additive and run the engine.For next oil change please do it every 5000 km ( 3000 miles)

Motor knock sounds like rocker arms or lifters?


If your engine is knocking the sound with be at the bottom of your oil pan but if you have lifter or rocker arm problems the sound will be at the top of your engine. One other thing you said your car has 315k it might be time to change your oil pump.

1996 chevy s10 4.3 vortex lifters knocking at start up but goes away after 10 minutes idling. changed oil and filter oil pump reads 58-60psi at idle and seems to be working.


High milage? Try engine cleaner, run for couple hundred miles and then use an additive like Restore. If it's just dirt this may help. Make sure you are using the correct viscosity oil for winter temps. If it's from wear only parts replacement will fix it.

MY 2000 Montero Sport has a loud knocking when i Start it UP ESPECIALLY WHEN ITS COLD IT GOES AWAY AFTER IT WARMS UP


Sounds like a hydralic lifter issue. These lifters operate the cylinder valves and run off oil pressure. When the engine is cold and the oil is thick worn lifters tend to rattle. When the engine warms up, everything expands and the lifters stop rattling. There is no easy cure for this except replacing the lifters. Sorry....

Trying to figure out where the knocking is coming from, on engine


It all depends how loud the knock is. A tapping valve can be caused by low oil level, or dirty oil. Topping up or changing oil will solve the problem. A really loud valve tapping is abnormal. Cars sometimes make what you call a spark knock when accelerating hard. Extremely loud knock coming from deep within the engine is a bad sign, which means the engine has failed. Further examination would reveal metallic residue on the dipstick.

Light knocking at the first start each morning


sounds like a high mileage motor. worn lifters that take a few minutes to pump up. Might add a quart of marvel mystery oil. To improve cold start upper cylinder lubrication.

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.

My car ticks sometimes. I have gotten a oil change and continue to check the oil and it still ticks. Pretty loud sometimes.


maybe a hydraulic lifter or a central bearing.... do you hav trouble accelarating at all? if its they hydraulic lifter, you will be fine for about 90k miles and even then nothing serious will happen, its just annoying. if its the central bearing on your motor, then you will have anywhere from 0-3000 miles left until your engine shuts down on you and your car stops moving. for me it's the hydraulic lifter witch triggered the knock sensor, which is there to detect knocks for oil related problems but unfortunaetly picked up my knocking too and thus went into its "energy saving" mode and slowed accelaration down ALOT in order to protect my motor. of course since it was a hydraulic lifter, this was pointless to me. if this is your case just take it to a mechanic and pay $40 to get the knock sensor unplugged. this won't solve the knocking itself but it will allow the car to accelarate at w/e speed you want. THIS IS NOT the solution to every knocking/ticking problem. there are MANY different ones out there so the best way is to get it checked out by a mechanic.
