Question about 1999 Daewoo Lanos

1 Answer

A freind of a freinds' Daewoo has a knocking sound (from the bottom of the engine I think) and a lot of clicking (from the valves or lifters on the top). While she was out of town her daughter used the vehicle when the harmonic balancer fell out of the car. After replacement, now she has all these noises. Could the noises be coming from the part installed incorrectly or did all this knocking wear out the harmonic balancer to fall off?

I have a 1989 dodge caravan 3.0 and it got low on oil and started knocking i took the valve cover off and it has hydraulic lifters and one of them is real soft would this mean a bad one and the cause of...


Most probably the lifter has gone bad, but if it is a LOUD knocking sound, it is possible one of the crankshaft / connecting rod bearings has been damaged. Usually a bad valve gives more of a "clicking" sound.
A bad camshaft lobe will also cause a "knocking" sound usually with an engine with high mileage.

350 Chevy knock might be a blown rod or a lifter stuck


Knocks in the engine can be defined by the frequency that it happens . If it is a cam follower it would be a constant knock and there would be more than one as if the cam follower or cam lobes are failing . A heavy knock can be a big end or a main bearing failing. Remove the plug wire and if it is a big end the sound will be a lot less as there is no combustion pressure pushing down on the crank pin. When you have got the rod you think it is then remove the plug as well and there will be virtually no noise when running. If the oil pressure is good at idle then the noise may be a broken ring or cracked piston. All produce a knock in an engine A stuck lifter should be holding open a valve so you will have a miss as well as the knock.

Having a "clicking" sound coming from engine, or dull "thumping"


could be anything from belt noise to lifter tick to rod knock..lifter tick is under the valve covers..rod knock sounds like hitting the block with a hammer..if its rod knock see what your oil pressure is.. should be around 30 to 45 psi cold..warm will be as low as 15..depending on oil type..most lifters can be adjusted by removing the cover and doing adjusting depending on the vehicle..good luck

How to set timing and distributor in 1987 4.3 mercruiser(chevy)


If the distributor is a 180 out,just start the plugs wire number 1 directly across from where it is now,and if it is 180 out,it should be back firing .Now on adjustment of the lifters,after it is running,loosen each one at a time until you hear it clicking,then turn it down until you do not hear the clicking any longer,and add one quarter turn.If this was at all helpful,please rate,thank you.

I have a 1998 GMC Sierra, when I start it in the morning it makes a knocking noise but once it warms up it goes away, what could be causing this?


We really need to know more about what kind of knocking you are hearing.

Pinging, clink clink, sounds like the time you got bad gas and put a strain on the engine causing it to knock. Airflow sensor telling the injectors how rich or lean to mix the fuel. Computer sets fuel air mix. timing , ect to match operating temp and if it is going bad throws the whole thing out of balance.

Ticking... click click click sound from the top of the engine that gradually fades,,( lifters on cam and valve chatter) sticking lifters can be treated with oil additive to clean them out if they aren't stopped up to bad. If that doesn't work or the noise keeps getting louder you need to have someone look at it or you can damage your cam or bend a valve and that can lead to a cascade failure of cam. lifters, valves and possible broken pistons.

Knocking. KNOCK KNOCK knock knock,from the bottom of the engine that fades ( rod bearing worn and slapping the crank til it gets enough oil to float it on the crankshaft or crank bearings worn and bearings trying to spin in the races)
If it is a hard knock could be a worn rod bearing or a partially stopped up oil port in the crankshaft that doesn't let the oil do its thing until it is warmed up. This problem can be slowed down with cleaning additives but the damage has already been done and will do nothing but get worse over time. If it is a bottom end bearing don't let it totally fail. If you have a mechanic you trust get him to listen to it and help you figure out what needs to be done. Once you have heard these noises and have someone point out the differences you don't forget them.
Remember. Sooner you get this figured out the less damage done and the cheaper the repair bill will be.

Ticking noise from engine


You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.
