Lifters would tick or rattle. A knock is usually lower in the engine, a rod or piston in most cases. The lifters are under the valve covers.

    Well then you could pull the valve covers and check to see which ones are making noise. Not much to look at tho.

    Only you can decide that. If the cost of repairs is over 50% of the value of the car, probably not.

SOURCE: rod knocking

It is true, however you will not likely be happy with the performance or fuel mileage. The 4.3 is too small and will be working too hard. If you are going to replace the engine you would be wiser and happier with a 305 instead. You only lose about 20 horsepower but you will gain fuel mileage over the 350. With a little careful driving you can get the same mileage out of a 305 as a 4.3 in a mid size car. Hope this helps.

SOURCE: 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.

My Daihatsu v1160r has a slight knock in da engine .what's da problem


Several things can cause a knock. Depends on several things. Does it only knock when driving but not at an idle: then it is probably low octane fuel. If it knocks constant and sounds like you are taping on the bottom of a ceramic coffee cup with your knuckle, it is a piston wrist pin. Any other knock can be a rod bearing or lifter (tappet) as they also knock constantly as well.

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 !

My 1994 nissan sentra has a bad knocking in it. can it be a stuck lifter?


Knocking is most certainly not plugs and wires. A lifter could be it or you could have a broken piston rod/end. Not good and should be looked at by a mechanic.

2001 S Type V8- moderate to loud ticking sound in the engine (sounds like metal to metal contact). The ticking is constant, at idle or throttled. One mechanic thought it might be the #8 lifter spring?


Thanks for choosing FixYa and welcome. That is possible. More then likely, it is a associated with the valve lifter. If it was a rod, you would hear a knocking sound compared to the ticking sounds a bad lifter gives off. As far as which lifter it is, the only way to know for sure if by taking off the valve cover and examining the lifters. You are in the right area though. Check your lifters and you should fine what is causing the ticking. Put all your focus on that area. Your friend sounds like he knows what he is talking about so he may be able to help you work on it if you are not able.

I have a 2004 Ford Explorer with a knocking sound coming from the engine. Was told I could be the timing chain. But it's not. What else could be making a loud knocking sound? Thanks.


If your truck has the 4.6 or 5.4 V8 then you know it has two timing chains. The lifters could be causing the knocking noise. If it sounds like it's coming from the top then I would suspect lifters. If it sounds like it's coming from the bottom of the engine then I would suspect main or rod bearings.

It could very well be a valve or lifter. The low oil may also cause the lifters or rods to knock.
As long as you aren't loosing oil or coolant, jeep runs good, and the knocking is not extreme, than add oil and you should be ok.

Engine knock dont know i f it's a lifter or oil pump


The firing timing is too advance or too retarded. When you accelerate the engine, if it loses power and knock, the timing is retarded and if it accelerate quickly and knock then the timing is advace.
